HOWTO: Fancontrol

[remmelt]

Controlling the speed (and sound!) of your CPU fan is easy!
Disclaimer: this can ruin your hardware. A CPU fan is needed to cool your CPU and in this howto it will be turned off for a couple of seconds. If you are not comfortable with doing this, don't!

Update Nov 7, 2007: this still works in Gutsy Gibbon! Hurray!

Setup lm-sensors
First, you need to set up lm-sensors. This is explained here (http://ubuntuforums.org/showthread.php?t=2780). That's for Warty, but still works under Hoary.

Once you have lm-sensors installed, you should have a readout with 'sensors'

$ sensors

+3.3V: +3.42 V (min = +3.14 V, max = +3.47 V)

Notice that my CPU fan is running really slowly, only 1100 RPM. The CPU temp is a little high, so I need to do some tweaking of the config there. The fan can run so slowly and quietly, because it's a large 12 cm fan made by Zalman (it's the 7000B AlCu). If your output does not display an RPM for your CPU fan, and you are positive it is running, you need to increase the fan divisor. If your fan speed is shown and higher than 0, skip the next step.

Increasing fan_div
The first line of the sensors output is the chipset your motherboard uses to read the speeds/temps/voltages. Make a backup first:

$ sudo cp /etc/sensors.conf /etc/sensors.conf_original
Edit the /etc/sensors.conf file as root

$ sudo gedit /etc/sensors.conf
and look up your exact chipset. The names all look alike, so make sure the one you are editing is yours. Add the line fanX_div 4 near the start of your chipset config. Replace the X with the number of your CPU fan's, for me that was 2. You have to figure out for yourself which one it is, but it's probably 1, 2 or 3.

Save, and run

$ sudo sensors -s
which will reload the sensors.conf's set variables.
Run sensors again and check if there is an RPM readout. If not, increase the divisor to 8, 16 or 32. YMMV!

Here is a sample from my sensors.conf

chip "w83627thf-*" "w83637hf-*"

label in0 "VCore"
label in1 "+12V"
label in2 "+3.3V"
label in3 "+5V"
label in4 "-12V"
label in7 "V5SB"
label in8 "VBat"

compute in1 ((28/10)+1)*@, @/((28/10)+1)
compute in3 ((34/51)+1)*@, @/((34/51)+1)
compute in4 (5.14*@)-14.91, (@+14.91)/5.14
compute in7 ((6.8/10)+1)*@ , @/((6.8/10)+1)

set fan2_div 8

<snip>

You can safely ignore anything that's not fanX_div. I would advise you to leave the other default settings as they are.


Patching pwmconfig This is no longer needed if you run Dapper! Go to the next step unless you're running Hoary.
There is a bug in pwmconfig (https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=145294) that you need to fix.
This is true for the version currently in Hoary, version 2.8.8-7ubuntu2.

First, try running pwmconfig:

$ pwmconfig
if that gives you the following error:
/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed
than you need to apply this fix. If not, proceed to the next step.

Backup:

$ sudo cp /usr/sbin/pwmconfig /usr/sbin/pwmconfig_original
Open pwmconfig:

$ sudo gedit /usr/sbin/pwmconfig
and go to line 68. Delete these three lines:

MATCH='*/fan[1-9]_pwm'
else
MATCH='*/pwm[1-9]'
and replace with:

MATCH='*/pwm[1-9]'
else
MATCH='*/fan[1-9]_pwm'
You just turned the if/else around! Now pwmconfig should work.

Run pwmconfig

$ sudo pwmconfig
One by one, all fans will be tested for 'speedcontrol' (Pulse Width Modulation, actually). Follow the onscreen help. Pwmconfig will write a config file in /etc. I set the interval to 5 seconds, just to be safe, but 10 should be fine too. Let the script run until you see "Select fan output to configure, or other action:" (all default options are fine, you can basically enter you way through the script).

Now press 5 to look at the configuration file. Press 1 to edit settings. Select a temperature that matches your CPU temp (usually the same number as the fan number, but check and double check!). Go with the defaults until you see: "Enter the minimum PWM value (0-255)
at which the fan STARTS spinning (press t to test) (150):"
Here, press t.
Keep pressing enter until you hear (or better: see) the fan spinning up. Then, press y and enter.
Same for the next step, but the other way around. If you see the fan stops spinning, press y and enter.

Press 5 again to display the config file one more time, then press 4 to save and quit. Almost there!

My /etc/fancontrol config looks like this:

INTERVAL=5
FCTEMPS= 1-0290/pwm2=1-0290/temp2_input
FCFANS= 1-0290/pwm2=1-0290/fan2_input
MINTEMP= 1-0290/pwm2=43
MAXTEMP= 1-0290/pwm2=53
MINSTART= 1-0290/pwm2=120
MINSTOP= 1-0290/pwm2=105

this is an example!

Starting fancontrol
The last step is to start up fancontrol. Enter this:

$ sudo fancontrol &
Now you can see and hear that your CPU fan is running slower, unless your CPU heats up. Good stuff!

[B}Starting fancontrol automatically on boot[/B]
Create a file called "fancontrol" in /etc/init.d:

sudo gedit /etc/init.d/fancontrol

And paste this in there:

log_success_msg " stop - stops system-wide fancontrol service"
log_success_msg " restart, force-reload - starts a new system-wide fancontrol service"
exit 1
;;
esac

exit 0


Save and close, then run
sudo update-rc.d fancontrol defaults 99 01 and you should be set.

(Thanks, Mr Wonka and jotape99!)


I would advise you to have some sort of fan/temp monitoring software installed. There is a nice one in gkrellm, or you can use xsensors.

Most of this howto is from here:
http://www.fedoraforum.org/forum/showpost.php?p=161610&postcount=5
Check if your hardware is supported here:
http://www.almico.com/forumindex.php

[Mr Wonka]

And if you want to have it startup on boot.


#!/bin/sh
#
# Fancontrol start script.

Stick this in a file called 'fancontrol' in your init.d startup scripts. eg.


/etc/init.d/fancontrol

Add this to your startup scripts in the usual way.

[remmelt]

Don't forget to


$ sudo chmod 0755 /etc/init.d/fancontrol

and create a symlink to that script in rc3.d, for example.


$ sudo ln -s /etc/init.d/fancontrol /etc/rc3.d/S99fancontrol

(thanks for that, by the way!)

[picpak]

I fixed the code in pwmconfig, and it still doesn't work...any ideas?

*edit* Nevermind...I fixed it :)

[ubuntu dave]

Hi all, thanks for this great guide, worked perfectly for me so far (yet to reboot ;-) ).
One thing of note that occured for me using the script kindly provided above:


sudo /etc/init.d/fancontrol start
* Starting fancontrol daemon...
start-stop-daemon: Unable to open pidfile `/var/run/fancontrol/.fancontrol-pid' for writing: No such file or directory


# Defaults
DAEMON=/usr/sbin/fancontrol
PIDFILE=/var/run/fancontrol/.fancontrol-pid
PATH=/sbin:/bin:/usr/sbin:/usr/bin

I had to change the PIDFILE path to:


# Defaults
DAEMON=/usr/sbin/fancontrol
PIDFILE=/var/run/fancontrol-pid
PATH=/sbin:/bin:/usr/sbin:/usr/bin

I don't know if this was something specific to me....... But incase it helps others.

[bored2k]

I would seriously have a heart-attack just by trying this (I don't even need for it to _not_ work O.o). Just reading the red disclaimer sends shivers down my spine.

don't give them ideas :roll:

[remmelt]

I guess the point is that it makes my life (even more) liveable because it makes the noise from my computer less. The cpu fan doesn't need to run 100% all the time, and I have described a way to make it less noisy.

That said, you shouldn't be running stuff like this on a server. Servers need all the cooling they can get, plus they are usually stored in places where no-one can hear the noise they make. Moreover, Ubuntu is a desktop-linux, right?

[remmelt]

Geesh. What if a virus installed one of these things? My paranoid brain can see whole multimillion dollar server rooms catching on fire now.

You used to have Windows installed, right? ;)

Just kidding. It is a scary thought. This way, a virus could do actual physical damage to a computer. On the other hand, most companies value the data on the drives more than the hardware. Hardware is replacable, (unbackupped) data isn't. Virusses tend to steal or corrupt data more than mess up computers like they used to.

[|cassidy|]

I fixed the code in pwmconfig, and it still doesn't work...any ideas?

*edit* Nevermind...I fixed it :)


Hello, the pwmconfig patch isn't helping the situation in my system.
I still get the
"/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed" error.

:confused:

Any help is appreciated.

[remmelt]

Are you very sure you corrected the pwmconfig file right?

If so: it may be right, you may not have any pwm configurable fans in your computer. Most Dells don't, for instance, even the new ones.

Do you get any results in fancontrol under Windows?

[|cassidy|]

Yes, I've triple checked the procedure :)

I've got a desktop pc, via kt266 chipset and in windows I control the fans' speed using Speedfan.

I did a search on the forum and found this
http://www.ubuntuforums.org/showthread.php?t=28465&highlight=pwmconfig

I have the same motherboard chipset and the same kernel version.

I really gotta lower these fans, I've got low temperatures and a fan that sounds like a vacuum cleaner.

[remmelt]

Did you do all the things in here (http://ubuntuforums.org/showthread.php?t=2780)? If you go "sensors", what does it output?

[|cassidy|]

Yes that's the howto i followed to make lm-sensors working.
This is the output I get.

[qalimas]

don't give them ideas :roll:

A program that does this that runs on Windows would be the end of Microsoft as we know it, anyone know how to port it? ;) Viruses, moms, 3 year old kids changing fan speeds and heating up hardware, that'd be hilarous :D

Nice guide, I'll give it a try on an old test computer shortly ;)

[remmelt]

Yes, it's called speedfan and it's pretty good! Works very well under Windows.

[Evil Dax]

I've got the PWMconfig and LM-config working,
it's doing fine on both my fans (nforce2)
However, one of those fans is set to cool my HDDs.
I have read most of these forums, but can't seem to find my answers:
I've installed HDDtemp to monitor my discs (didn't find other tools for it)
But: is it possible to add these values to PWMconfig, so that fancontrol also regulates this fan ?

PS: I'm a linux-newbie, installed this last week....

[yesplease]

Just a warning, Speedfan was/is a good program for windows, but is not maintained or updated any more for some time now. Be carefull.

(I use the fancontroller made by MSI for my motherboard on windows, which works for me, but is considered malware by others :) )

[jotape99]

Thanks for this great how to.

My little contribution: to add the start/stop links, I rather prefer the command:

sudo update-rc.d fancontrol defaults 99 01
I changed the pid file in the script:

PIDFILE=/var/run/fancontrol.pid

[mozetti]

Nevermind, got it sorted.

[mistapotta]

I recently built a computer with an Intel D945Gcz motherboard and an Intel Pentium-D 3.0 processor, and the fan sounds like a vacuum cleaner. I'd like to find a way to regulate the fan speed, as other operating systems seem to be able to do it.

I installed lm-sensors as shown here (http://ubuntuforums.org/showthread.php?t=2780) and got an output from it:

as specified, I get

I understand there are situations where my fan would need to run near 5300 RPM, but the baby in the next room does need to sleep.

Anyone have any ideas?

~Tony David Potter

[remmelt]

For starters: do not try to patch the pwmconfig thing if you are running dapper. It's been fixed, you no longer need to patch the script.

mistapotta: It looks like your fan is being picked up correctly by lm_sensors. The speed is being reported, so you won't have to change the fan's divisor. You only need to do this if the fan is running so slowly that lm_sensors thinks it's turned off. Looks like this is not the case.
Also, fan1_div would point to a fan named fan1. Looking at your output, the CPU fan is actually called CPU_Fan (conveniently!) so it would be CPU_Fan_div, I guess.

You're now ready to run pwmconfig! Good luck!

If you want to silence your computer even more, I suggest getting a larger fan. I have a 12" one made by Zalman, and it's very quiet with the rotations turned down. With my CPU (amd athlon 64 3000+), it sometimes even turns off alltogether. I don't know how hot your Pentium runs though, could be a lot hotter. Anyway, try the pwmconfig and if it's still too loud after that you can always look at a larger fan.

[mistapotta]

The CPU_Fan is just a label set in my sensors.conf.


# Fan inputs
label fan1 "CPU_Fan"

and changing CPU_Fan_div still gives "unknown feature name" error

When I tried to run pwnconfig, this was the output:




~$ sudo pwmconfig
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.

Any idea how I can change the permission denied when accessing pwmX_enable (X=1,2,3)?

:( http://www.lm-sensors.org/ticket/2071

That's not your exact motherboard, but it looks like the same error...


Tried "chmod 644 /sys/bus/i2c/devices/0-002e/*enable*" and pwmconfig ran without complaint, but to no effect (fans did not appear to stop/start when tested). Fan speed is still constant.

According to http://lists.debian.org/debian-user/2005/10/msg03283.html the lm85 kernel module needs to be patched to correct an Intel BIOS misfeature. I haven't tried this.

I'm sorry I can't help you more than this..

[fakie_flip]

Hackers who know about changing fan speed could be a dangerous and expensive thing. Window's XP is easily hacked through trojans, and if the people who got into a Window's XP computer were able to change the fans' speeds, BYE BYE cpu. Those things would be smoking without a fan. They can get hot.

[fakie_flip]

why is my cpu fan speed not being shown? i followed the directions.

If it is built-in into your kernel, you can safely skip this.
i2c-dev is not loaded. As you are not root, we will just hope you edited
`/etc/modules.conf' for automatic loading of
this module. If not, you won't be able to open any /dev/i2c-* file.

We are now going to do the adapter probings. Some adapters may hang halfway
through; we can't really help that. Also, some chips will be double detected;
we choose the one with the highest confidence value in that case.
If you found that the adapter hung after probing a certain address, you can
specify that address to remain unprobed. That often
includes address 0x69 (clock chip).

Some chips are also accessible through the ISA bus. ISA probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.

As you are not root, we shall skip this step.

Some Super I/O chips may also contain sensors. Super I/O probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.

As you are not root, we shall skip this step.

Sorry, no chips were detected.
Either your sensors are not supported, or they are
connected to an I2C bus adapter that we do not support.

# sensors-detect revision 1.393 (2005/08/30 18:51:18)

This program will help you determine which I2C/SMBus modules you need to
load to use lm_sensors most effectively. You need to have i2c and
lm_sensors installed before running this program.
Also, you need to be `root', or at least have access to the /dev/i2c-*
files, for most things.
If you have patched your kernel and have some drivers built in, you can
safely answer NO if asked to load some modules. In this case, things may
seem a bit confusing, but they will still work.

It is generally safe and recommended to accept the default answers to all
questions, unless you know what you're doing.

We can start with probing for (PCI) I2C or SMBus adapters.
You do not need any special privileges for this.
Do you want to probe now? (YES/no):
Probing for PCI bus adapters...
Use driver `rivatv' for device 01:00.0: RIVA UVTNT2
Use driver `i2c-sis96x' for device 00:02.1: Silicon Integrated Systems SMBus Con troller
Probe succesfully concluded.

We will now try to load each adapter module in turn.
Load `rivatv' (say NO if built into your kernel)? (YES/no):
FATAL: Module rivatv not found.
Loading failed... skipping.
** Note: rivatv module is available at http://rivatv.sourceforge.net/
Module `i2c-sis96x' already loaded.
If you have undetectable or unsupported adapters, you can have them
scanned by manually loading the modules before running this script.

To continue, we need module `i2c-dev' to be loaded.
If it is built-in into your kernel, you can safely skip this.
i2c-dev is not loaded. Do you want to load it now? (YES/no):
Module loaded succesfully.

We are now going to do the adapter probings. Some adapters may hang halfway
through; we can't really help that. Also, some chips will be double detected;
we choose the one with the highest confidence value in that case.
If you found that the adapter hung after probing a certain address, you can
specify that address to remain unprobed. That often
includes address 0x69 (clock chip).

Next adapter: SiS96x SMBus adapter at 0x0c00
Do you want to scan it? (YES/no/selectively):

Now follows a summary of the probes I have just done.
Just press ENTER to continue:

Driver `eeprom' (should be inserted):
Detects correctly:

Busdriver `i2c-sis96x', I2C address 0x50
Chip `SPD EEPROM' (confidence: 8)
* Bus `SiS96x SMBus adapter at 0x0c00'
Busdriver `i2c-sis96x', I2C address 0x51
Chip `SPD EEPROM' (confidence: 8)

Driver `it87' (should be inserted):
Detects correctly:
* ISA bus address 0x0290 (Busdriver `i2c-isa')
Chip `ITE 8705F Super IO Sensors' (confidence: 9)


I will now generate the commands needed to load the I2C modules.
Sometimes, a chip is available both through the ISA bus and an I2C bus.
ISA bus access is faster, but you need to load an additional driver module
for it. If you have the choice, do you want to use the ISA bus or the
I2C/SMBus (ISA/smbus)?

To make the sensors modules behave correctly, add these lines to
/etc/modules:

#----cut here----
# I2C adapter drivers
i2c-sis96x
i2c-isa
# I2C chip drivers
eeprom
it87
#----cut here----

Do you want to add these lines to /etc/modules automatically? (yes/NO)yes

my read out on sensors = " no sensors found " how do i fix this?
Is there a nice gui type thing for fan control . Im very familiar wiht linux but, this lappy is my life and rather not kill it.

Any hint / tips / tricks?

[remmelt]

If you can't be sure if what you are hearing is hd or fan hum, you have to ask yourself if you really need to lower the fan speed at all. Also, as stated, if you aren't a 110% sure of what you are doing, don't try this. It can kill your CPU if you aren't careful.

Having said that, it sounds like you haven't installed lm-sensors yet. Please check out the first post and tell me where you get stuck.

Also is there a "gui" type thing someoen has made?
To switch fan though modes?

Make fan speed faster would be nice.

If you haven't changed your fan speed, it's set to maximum. You can only lower the fan speed with this program. If you don't want to lower your speed, don't use it!

running fiesty (dist-upgraded, not a clean install) on a Shutlte with a nForce2 chipset

for whatever reason, my pwm1_enable file already had the value "1" in it and the permissions were -r--r--r-- so there was a permission denied error. chmod'ing that caused an I/O error.

I edited /usr/sbin/fancontrol and commented out the calls to pwmdisable and pwmenable and it works now.

[starfry]

Hello,
I can't get pwmconfig to work. It is responding with the following error mentioned earlier in this thread:


/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed


Now, I have tried to change the code as mentioned earlier, but I guess I have a later version because the code around line 68 does not look like that mentioned earlier:



MATCH='*/pwm[1-9]'
PWM=`echo $MATCH`
if [ "$SYSFS" = "1" -a "$MATCH" = "$PWM" ]
then
# Deprecated naming scheme (used in kernels 2.6.5 to 2.6.9)
MATCH='*/fan[1-9]_pwm'
PWM=`echo $MATCH`
fi
if [ "$MATCH" = "$PWM" ]
then
echo $0: 'There are no pwm-capable sensor modules installed'
exit 1
fi


I looked for files similar to "pwm[1-9]" or "fan[1-9]" and could only find these:

Please if anyone can offer any pointers? The only solution at the moment is almost unthinkable: returning to Windows where my fans are very quiet.

[chrwei]

starfry: that means you don't have any PWM enabled hardware, or the hardware you have has no linux driver. you simply can't use fancontrol because your hardware does not have fan speed control support.

[starfry]

But my hardware must have fan control because it is controlled when in Windows.

My motherboard is an ASUS CUV4X-D (Coppermind PIII dual).

How do I find out if I need a Linux driver, and what might that driver be? If I know what module I need then I can try loading it.

Thanks for helping...

[chrwei]

there are other ways besides PWM to control the fan speed, and fancontrol doesn't support those ways.

see http://vip.asus.com/forum/view.aspx?id=20060730030619838&board_id=1&model=P5WD2+Premium&page=1&SLanguage=en-us

3 pin fan uses DC voltage control, 4 pin fans use PWM. I'm not aware of any P3 fans with 4 pins.

I can't get the startup script to work. When i reboot my computer and run >ps -e fancontrol isn't listed and the fans spin att full speed. I does however set a .pid-file in /var/run/ since it complains about it when i try to start manually. I'm using this fancontrol script: http://volker.dnsalias.net/linux/tech/lm_sensors/fancontrol Could it be messing something up?

Running Ubuntu Feisty.

[bomanizer]

Hi,

I'm wondering.. does the script start every time the system boots up? How about surviving a hibernation? I think these are general init-script issues... or?

cheers

[gheywood]

I have got as far as running "sudo pwmconfig" and it successfully stops my fan so I can listen to it. However, when doing the config, it is never able to start or stop the fan with the "t" function.

I run an ASUS M2M-MX motherboard.

Is there some reason why it can stop the fan when pwmconfig is run, but cannot start/stop it when using the "t" option?

I am a little concerned about using it otherwise, but it would be really nice to get it to work...

This is the output of the first run:

Hi y'all,

Wondering if anybody could help me out. Have followed howto for lm-sensors and fancontrol, seems to work okay until pwmconfig and then the fans don't stop when it says they should.

Set up lm-sensors and get output from sensors:

Did you see/hear a fan stopping during the above test (n)? n

Testing is complete.
Please verify that all fans have returned to their normal speed.

The fancontrol script can automatically respond to temperature changes
of your system by changing fanspeeds.
Do you want to set up its configuration file now (y)? n

I can't seem to get the startup script to work either, any idea?

Hi all,

I have a M2N-E MOBO with Athlon 3800 x2 processor. I got my fancontrol working with my MOBO.

I have written down what i did in my blog for my references in future. Anyone interested can refer to it. Hope this helps. :)

[NeillHog]

Thank you for the great how to.

I now have everything running and there is a direct correlation between CPU temperature and CPU fan speed as shown by KSensors (Kubuntu) so I assume that everything is running as it should. Automatic starting is also OK.

I just have one problem -

During the close down process for Kubuntu my CPU fan switches off completely. I assume that this is caused once it unloads fancontrol.

Is there a command to unload fancontrol?
Can I do this automatically as a part of closing down Kubuntu? I suppose what I asking is "is there a way to automatically close fancontrol before continuing with the shut down process.

Thanks again for a great how to!

Neill

[NeillHog]

The problem is solved :-)

It only happens if I start fancontrol from hand in the console.
Doing it as in the how to and everything works. During shut down the fan speeds up!

Thank you!

[libos]

Was going to reply you. :)

Yes, the fan speeds up. I guess once the script is unload, no software is taking control over the fan so all fans will go full speed.

I get stuck at "Increasing fan_div" - here is my sensors output:

Notice that my fan1 is nearly 3000 rpm. In my case my cpi heatsink is facing sideways, and the fan blows air from the front, across the heatsink, and out the back. There is a 12cm fan on the back that runs much faster than my CPU fan - probably because it just sucks and the cpu fan doesn't have to work much. In my BIOS the case fan is always about 4-6x faster than the cpu fan. So I am not seeing my CPU fan speed. Following the instructions in the post to


look up your exact chipset. The names all look alike, so make sure the one you are editing is yours. Add the line fanX_div 4 near the start of your chipset config. Replace the X with the number of your CPU fan's, for me that was 2. You have to figure out for yourself which one it is, but it's probably 1, 2 or 3.

does NOT work, because I can't find a chip in the entire sensors.conf file that is named it8718. I found it871, it8712, and it8716, but NO it8718. I wonder if I need to create one myself, however I don't think that would be a good idea given my level of knowledge and the danger of permanently frying my computer.

If any of you have any advice please give it!

[libos]

Not sure this can help you. I found the section to configure your chipset (it8718). I got the clue from

http://www.lm-sensors.org/wiki/Devices

Search for "it8718". It's using the it87 driver. In the sensors.conf file, i found the section at line 1537.

Good luck. :)

[JohnLai]

I manage to configure the fancontrol properly, but now I want to disable the fancontrol completely. What step should I take? Delete the fancontrol script at /etc/init.d/fancontrol only?

[Evil Dax]

since Gutsy I'm unable to get it running at startup, while Feisty and Edgy worked smoothly... Any ideas?

[tweedledee]

JohnLai: In the event you haven't worked it out yet, you should delete /etc/init.d/fancontrol at a minimum, then execute

sudo update-rc.d fancontrol remove to remove the links. You can also delete the /etc/fancontrol file if you don't intend to return to using fancontrol.

Evil Dax: delete your /etc/fancontrol and start over. When I upgraded to Gutsy, the names of the devices changed, so the old fancontrol settings did not work. Actually, you probably want to note your exisiting configuration, so you can set it up the same way again using the original process.

I had this problem on one of my desktops (which has the 83637hf chip and uses the 83627hf driver), and just found the solution today. My BIOS was controlling the fan (but naturally did not have any configuration available). To override the BIOS control, load your chip module (w83627thf in your case) with the paramter "reset=1". To test this, first run

sudo modprobe -r w83627thf to unload the module if you have already done a modprobe and/or put the module in your /etc/modules. Then run

sudo modprobe w83627thf reset=1 and try pwmconfig again. With luck, your fans will now be controllable. If that does not work, you can also try "reset=0" and "init=0" instead of "reset=1" (based on Google searches, sometimes those work for other people). Always unload the module between new modprobes, though, or it will just disregard the new load. You'll have to add whichever command worked after the chip name in /etc/modules to ensure proper loading during boot.

Just for completeness, I should note that on my computer, the issue was that the BIOS was turning the fans so far down the computer was in serious danger of overheating when the processor was working hard - so when I used the "reset=1" command, my fans jumped up to full speed. Since yours are already full speed, you may not notice any immediate change.

[LordKelvan]

tweedledee: THANKS!!! Finally, it works (I tried it using "reset=1"). Now, I noticed a couple of things when trying this:


Even though the chip name is w83627thf, it actually uses the module w83627hf (it seems that module is used for both chips). For example, I had to do 'sudo modprobe -r w83627hf' to unload the module.
After I unloaded and reloaded the module, I noticed that when I ran 'sudo sensors' I had lost the CPU fan reading (it now reported 0 rpm with div=2), and that under beep_enable it said 'Sound alarm disabled' (it used to say 'Sound alarm enabled'). These changes persisted regardless of whether I reloaded the module without any extra parameters (i.e., 'sudo modprobe w83627hf') or with extra parameters (e.g., 'sudo modprobe w83627hf reset=1' or 'sudo modprobe w83627hf reset=0'). Hopefully the 'sound alarm' thing will be fixed with a restart, while I fixed the CPU fan reading thing using the method detailed below.
In order to get back the CPU fan reading (i.e., the reading I mentioned losing above), I had to follow the guide (on pg. 1) on how to change the fan_div to get readings on fans which are running, but reported as 0 rpm. For reference, I had to add the line 'set fan2_div 8' (it is fan2_div because my CPU fan is fan 2) to my /etc/sensors.conf file, under the section for w83627thf. Please note that the sections are according to chip name and NOT module name (I would imagine chip name and module name are usually the same, but they were a little different on my machine as I mentioned earlier in point #1). This is why I placed it under the section for w83627thf, and NOT w83627hf.


Once again, things are finally working, so thank-you very very much to tweedledee, and of course, to remmelt for creating this guide in the first place.

Oh, one more thing - I think the guide forgets to mention that you should make the fancontrol file in /etc/init.d (NOT the one in /etc) executable. I did so with the command:


sudo chmod +x fancontrol

Maybe remmelt could add this to his/her excellent guide.

I neglected to mention I had a similar experience, using the w83627hf module but w83637hf chip (and did it take me a while to notice that 2->3 change), and also had to change the fan_div value for one of my fans. I don't recall if I had any alarm status changes. I'm not actually sure what the reset command does, other than allowing me to regulate the fan, but it is odd that it influences the display like that. I'm not noted any other side effects so far, though, so I'll take it.

[greys]

Thanks for a great guide!

[eje_s]

I'm using a Asus A8N-SLI deluxe Nforce4 motherboard and had great problems getting fanspeed working. Speedfan under windows works, so I know that fan speed control is possible.

After many hours of googling I found out about kernel modules parameters and that solved my problem.

The chip found by sensors-detect is: it87 (it8712)
I don't use cool n' quiet, so by default the pwm controls is disabled, I'm not even sure that they will be enabled if so.
Newer kernels use /sys/class/hwmon/hwmon0/device/ as the base folder for these controls by the way. The goal is to have pwm[1-3] in that folder.

After the standard installation of lm-sensors I used these commands to solve my problem:

sudo modprobe -r it87
sudo modprobe it87 fix_pwm_polarity=1
ls /sys/class/hwmon/hwmon0/device/pwm*


The result should be that pwm1 to pwm3 now is listed.

Pwmconfig should now work as expected. However for me only pwm1 and 2 is usable and this is normal for my motherboard.

Now is the time to set up your fan control settings and enable fancontrol following any other guide. The later part of http://ubuntuforums.org/showthread.php?t=42737 for example.

I wish you a happy silent system!

Any ideas?

[libos]

Hi sha_man,

You might want to check out your mobo manual does your mobo comes with the pwm outputs. What is your mobo anyway?

[sha_man]

hey,
i have an Asrock 939Dual-SATA2 motherboard. Apparently, after some googling, i found out that other people with the same motherboard had similar problems with SpeedFan for windows (or whatever it's called). I think this motherboard does not allow any fan controlling.
What I will do, if nobody has any solution is to buy a hardware based controller.
Thanks anyway

[PheonixKotori]

sha_man: You've likely moved on since your last post, but I wanted to add this item for posterity.

One thing I haven't seen mentioned in fancontrol threads is the fact that some fans do not have speed sensors built-in. All my chassis fans are like that; you can tell because they only have 2 wires. fancontrol can adjust the pwm to their socket, but it has no idea how fast the fans are spinning. As such, pwmconfig always sees "no correlation," but I can physically inspect them to see that they have changed speeds.

This may not apply to your or anyone else's problem, but there you go.

[dd976]

Thanks remmelt for the guide! I have a question though. I've tried sensors-detect, and nothing is found on my c600 laptop (which smells like it's melting btw). I just have no fan activity whatsoever, and the fan was working in xp when it was installed on this computer. I've tried looking at the bios screen, and can't find anything there. Does anyone have any suggestions? Or can you point me to the appropriate thread/post please? Thanks! I need to turn this comp off for a while now, before it starts to smoke.:(

[cheetah1]

Well all that probably works well if you have a temp source.
Problem is that I don't quiet trust mine, as it is stuck on a constant 127°C.
The fan, however, is detected properly:


w83627hf-isa-0290
Adapter: ISA adapter
[...]
fan3: 2636 RPM (min = -1 RPM, div = 16) ALARM
[...]

It also stopped during the pwmconfig test (although it is a 3-pin fan..), so it is controlable. Question is: is there something i can write in the fancontrol config file to set it to a constant RPM or voltage, or do I need some other app to do that?
My server really isn't working hard, running a wordpress blog with 5 visitors a day on an Athlon XP 1700+ with 512 MB of ram, so it's not like it's going to run hot if I set it at say 1800 RPM... Right now though, it sounds like a hurricane in my folks livingroom...

[chrwei]

fancontrol just cats stuff to the sys files for PWM, you could do that manually.

however, Athlon XP's tend to run on the hot side, especially the older ones, so lowering the fan speed may make it too hot. does the temp in BIOS read a reasonable value? adjust the fan speed and reboot check it after a while. If the BIOS has a temp alarm set it to its loweest and see if you can trigger to, to make sure it works, then set it to 70C or 75C as a safety backup and let people know to unplug it if it squeals.

if you can spare the $20, just get a quieter fan, much safer thing to do since the older XP cpu's don't have thermal throttling, if it does overheat, it just catches fire where newer sysems will slow down and/or shut off via a BIOS function.

As I said, the CPU temp sits constantly on 127,5°C, both in bios and when running sensors. The fan is pretty new, and way quieter, and it's supposed to be able to handle 3000+ CPUs. It appears to be out of stock, but it's similar to this one (http://www.datorbutiken.com/se/default.aspx?Product=XILCPUK8), only the attatchment is different. Sorry about the Swedish, but I belive it can be understood anyway.

If you touch it when it's running, it's never particularly warm, usually just a couple of degrees warmer than room temperature.

An option, of course, would be to buy a harware fan controller with a proper temp sensor. I don't know. What do you think?

[chrwei]

I think its possible for a cpu core to get to 127C and have a cool to the touch HS when it is not installed properly. I wouldn't expect it to run for very long that way, few weeks maybe.

if the BIOS says 127C, then it either really is at 127C or your mainboard and/or cpu are failing

Oh but please...
This machine has run for about 5 or 6 years, the last 6 months constantly and it has ALWAYS said 127,5.That is called a faulty thermistor wich is very common on older systems.

Also, the heatsink is new, perfectly well installed, with a good thermal compund. It is, with an another attatchment on it, able to cool a 3600+ Athlon 64 CPU. With my Athlon XP 1700+ almost constantly running at idle I would guess it's at about 30-35°C.

I am aware that these processors tend to run hot. That is why it's on that temperature with a coolingfan. A more modern, or better built processor wouldn't need a fan to stay on that temperature.

Please tell me how to lower the RPM instead of trying to tell me that something is or will become broken. I know my hardware, but I'm not that good with Ubuntu.

[libos]

You could just tweak the config file to set MINSTART and MINSTOP to the same PWM value depends on your comfortable noise level. This should get your fan speed constant for all temp values.

Hope this helps.

[cheetah1]

Okey, great, now it works.
Until I close down putty, then the fan STOPS! So, ehm.. What do I do to keep it spinning? Without having to have putty running?
I could, of course, use a monitor and set it up directly, but should that really be necessary?

Hi guys !

I have this when I execute 'sensors':

coretemp-isa-0000
Adapter: ISA adapter
Core 0: +35.0°C (crit = +100.0°C)

coretemp-isa-0001
Adapter: ISA adapter
Core 1: +36.0°C (crit = +100.0°C)

And for pwmconfig I get:

/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed


My fans are always at their maximum speed and it's very loud (I had the same problem under XP). My notebook is an MSI GX700-046 (Performance Edition).

Don't hesitate if you have any idea to slow them a bit...

[iconoclast36]

Peace:

I'm having trouble running fancontrol adequately and need help restoring my system to it's defaults.

If anyone out there can help me control the fans on my computer, step-by-step, I'd appreciate it. I've installed lm-sensors and run pwmconfig, but am having difficulty with some of the configuration settings.

I'm working off a Sony Vaio PCV-RX463DS on Xubuntu Hardy. With 'sensors' I get the following readout:

My aim is to regulate the fans akin to how they ran in Windows -- i.e., system boots up, fans quiet down and start up again when system heats up. Presently the fans are fluctuating in speed -- and 'fan1' showing 0 RPMs worries me.

Thanks, everyone ;-)

I can't control them. They're making so much noise I can't work on Ubuntu any more. Temperature also seems odd (minus 54?) but on 8.04 was the same (however bios shows diffrently) and fan control was ok. most of the time about 1000 rpm. I've tried to change pwmconfig and made mkdev.sh as was before but with no efect.


P.S. Sorry for my English, I'm from Poland. ):P

[borgibo]

This is from a super newbie, to show my appreciation for the Fancontrol howto by remmelt.

I followed the instructions and succeeded in my 64Studio distro to render the fan speed rolling happily at around 350rpm ! with a cpu temp of around 36C ! My fan is a 12cm 'Coolermaster RR-CCH-PBU1-GP GEMINII S' with 1900 rpm max. ( Mobo Gigabyte GA-M61PME-S2, ram 2GB, cpu AMD64 x2 3800+ ).

I just now was able to activate pwm on reboot too, automatically, after I followed remmelt's next day's instructions ( June 20th, 2005 ) !

The only 2 things extra that I had to do, possibly due to not understanding the instructions properly, was that I had to configur both pwm1 and pwm3 ( pwm2 did not seem to have any effect ),to attain low speed, and I had to disable the 'smart' fan control from the mobo, otherwise it took over and raised the speed to around 1200 rpm.

[thierrybo]

Just one question. Do we need fancontrol any more with PWM fans?

As I understand, a PWM fan with a PWM enabled bios does more or less what fancontrol do, and automatically handled by bios?

[Hoyland84]

Thanks for this great HOWTO! I now have full control over the CPU fan and noise level has been reduced considerably. However the two chassis fans still make quite a lot of noise. They seem to be running at a constant full speed. I have one fan sucking in and one blowing out. They are not equipped with any RPM sensors and are parallel coupled from the same source. It doesn't seem to be a way to tweak them in the BIOS setup either.

Is there a way to reduce the voltage going out to these fans and by that way reduce their speed? I know this is possible by installing hardware and tune the voltage manually but I wondered if there is a way to do this with fancontrol or any other software.

You could buy some 4-pin-to-3-pin connectors and plug them directly into your motherboard if it has the jacks. Places like xoxide, newegg, zipzoomfly, frozencpu, etc. all sell those types of parts. Take a look and see what you can find; they're really, really cheap if you shop around, usually.

Hey OP & contributors, thanks a lot for the howto. Worked great on this socket 939 mobo! (DFI Lanparty Ultra-D)

Cheers!
-Downhill

PS: Wish they'd make the process easier, though. If it's gonna probe for when the fan stops anyway, why not use the numbers it collects automatically? *sigh* Well, at least it works well enough to get the job done.

I have been running the init.d script for a long time using 8.04 flawlessly. I recently upgraded to 9.04 and even though /usr/sbin/fancontrol still works as usual the init script does not.

Has something changed in way Ubuntu interprets the script? Furthermore I tried to find the log file where errors would be located but none of the log files in /var/log contains any information on fancontrol.

Hi guys, great thread - I've got this so close to working on Jaunty.

The /etc/init.d/fancontrol script won't work unless I sudo it, which means it won't run on startup. Any ideas why it's working for all of you lot but not me? I've only been using Linux for a few weeks so apologies if I'm being stupid!

In case it's useful here's what happens when I run it (I've edited the script to remove the --background suffix from the start-stop-daemon command so you can see what's going on):

[djurny]

attached is a gzip'ed tar file containing a modified /etc/fancontrol configuration file and a diff to generate a modified /usr/[local/]sbin/fancontrol..
some things i added are:
- multiple sensors per output
now you can have a fan controlled by lets say, 4 averaged or maximized coretemp readings instead of 1 cpu case temp sensor..
- "peak/hold" like operation
instead of fancontrol maxing out and idling fans on intermittent loads, the last highest pwm value is held on to for a specified amount of seconds..

maybe an idea to add these to the howto as a nice add-on?

anyway, let me know how you like it (or not) :)

[Nerevar144]

I've been trying to lower my power fan speed for a few hours now and I can't seem to crack it. I followed the guide and I get hung up on the pwmconfig command which gives me the "There are no pwm-capable sensor modules installed" message. I have a fintek super I/O chip. I was stumbling around and found this on the lm-sensors web site. Here's the url: http://www.lm-sensors.org/ticket/2332

That seems to be what i need, however it refers to a .patch file. How does it work. It appears to have html code in it. I'm CONFUSED... Hardware sensors are loaded and working as the hardware sensors applet is running and gives me cpu, gpu, hdd temps and cpu, and system fan speeds. I just can't seem to adjust them. (I bought an aftermarket CPU fan that is rated at just over 1 AMP and it's running at 3350 RPM which is kinda loud. I'd like to run it at half that :).

[zulek87]

Hi!

I did not want to set up new topic.

My mb has option that can automatically control fan speed, but rpm's are too high, so I want to decrease them. I also can use lm-sensors to do that, but if I start fancontrol and stop it, my fan is on max speed, I saw in script (/usr/sbin/fancontrol) part of code responsible for it:



function restorefans()
{
local status=$1
echo 'Aborting, restoring fans...'
let fcvcount=0
while (( $fcvcount < ${#AFCPWM[@]} )) # go through all pwm outputs
do
pwmo=${AFCPWM[$fcvcount]}
pwmdisable $pwmo
let fcvcount=$fcvcount+1
done
echo 'Verify fans have returned to full speed'
rm -f "$PIDFILE"
exit $status
}As we can see fans are restored to the max rpms. How to give back control to the BIOS when I stop fancontrol?

P.S.
I know, that fancontrol is for ppl who do not have this option in BIOS, so it's normal, that fans are restored to their max, but maybe there is a way to manage this?

Thanks for help!

[chrwei]

if the BIOS fan control isn't slowing down the fan enough, you have a cooling issue, or just a noisy fan. forcing it to run slower is likely to cause too much heat and then CPU damage. Keep in mind that lm-sensors isn't always exactly calibrated and so the temps you see can be quite wrong.

[iminhell]

I can't figure this thing out for the life of me. I went by a different install how-to because with it I gained control of my fan, though I use 'control' loosely. Right now my fan pulses and I have very little control over it. I can change the speed it spins to but not the speed it spins down to. ~4100 and 1900 respectively. It does not start on startup/reboot, I have to run:

sudo /usr/sbin/fancontrol
via terminal. I'm fine with that because at least I can turn it on at my discretion.


Take the modprobe lines it recommends and paste them into the appropriate /etc/rc.d/xxxx file to be executed at startup.
http://www.lm-sensors.org/wiki/FAQ/Chapter2

That is confusing to me. I took a chance and edited what:

sudo sensors-detect
output:

# Chip drivers
w83627hf

Then found "w83627hf" in "/etc/sensors.conf" and edit "set temp1_over 38" (line 512) and "set temp1_hyst 30" (line 513). Values prior where 50 and 37. I thought this would turn the fan on to a higher speed at a lower temp, seems not though.

Maybe the fan is supposed to pulse, kinda doubt it though. Being I haven't seen it work in person . . .


So what do you guys need so you can help me get this thing working properly?



(Wish it where nice and simple like Speedfan for Windows, set a speed and let it go, adjust on the fly as desired)

[mhousel]

I can't figure this thing out for the life of me.

Same boat here...

Can't figure out fancontrl, nothing works like the examples.
Can't figure out pwmconfig either, nothing works like the examples.

From another thread I tried:

Re: HOW TO: Install and configure lm-sensors
I've tried all of this and still nothing will allow me to kep the fans running on my Toshiba satellite laptop.

The lm-sensors and sensor-detect do not work as shown here on this particular laptop it seems.
I can't get the sensor-applet to run either. (It is installed but not in /usr/bin as is the sensors executable)

The real problem is that the temperature limits seem to be set incorrectly and I have yet to find a way (that works on my laptop) to lower them.

No problems until I try to play any streaming video full screen then the CPU overheats because the fan doesn't speed up enough until right about the time it shuts off due to over temp.

Nothing related to monitoring or controlling the fan speeds works on this computer it seems.

From the files related to ACPI--
cat /proc/acpi/thermal_zone/THRM/cooling_mode
<setting not supported>

cat /proc/acpi/thermal_zone/THRM/polling_frequency
<polling disabled>

cat /proc/acpi/thermal_zone/THRM/state
state: ok

NOTE: This matches the sensors output and the output shown on the toolbar by kSensors.

cat /proc/acpi/thermal_zone/THRM/temperature

cat /proc/acpi/thermal_zone/THRM/trip_points

And I've tried the things I can find related to changing the argument in grub:

# /boot/grub/grub.cfg.

Oh, and also the things related to HOWTO Fix A Buggy DSDT File
If I decompile and recompile my DSDT file the only errors are related to some sort of warnings about line terminators, nothing in the code itself.

What I changed is the code below, instead of having...


start-stop-daemon --start -o -q -m -b -p $PIDFILE -x $DAEMON
start-stop-daemon --stop -o -q -p $PIDFILE

I made it have...


start-stop-daemon --start -o -q -m -b --pidfile $PIDFILE -x $DAEMON
start-stop-daemon --stop -o -q --pidfile $PIDFILE

This allowed me to start/stop the daemon properly! :)

Aloha Everyone,

I just finally got this working somewhat better.....the noise in the room is finally at a calmer state.

I did want to just show you my data and hoped that someone could take a look at especially the fancontrol file and tell me if you see any red flags.

I did do it on my own.....worked on it for a few days, did a lot of reading through posts and all that, and would hate to see all that time go down the drain.

I have an odd problem with lm-sensors. I add the module and so on, no problems there. Then I run pwmconfig (as sudo, otherwise is doesn't work), it tests two fans which I physically see stopping. Then when I setup the temperature configuration, and I get to the part when I have to setup the PWM values for minimum and maximum, I choose test (t).
But nothing happens, it sets the fan to 10 PWM, but it doesn't stop or slow down. So I tried setting all the values to 10 in the configuration and started the daemon, and it doesn't slow down the fans either.

[psyopper]

I don't know what I did wrong along the way but I had problems getting fancontrol to start at boot time correctly.

1. I had to go into my BIOS and disable the CPU Fan Control system. pwmconfig would detect and operate the fans and set up a fancontrol profile, but the profile was doing nothing because the BIOS was overriding the input.

2. I had to do the same renaming of the fancontrol.pid as described very early in the thread.

3. I had to use sudo update-rc.d -f fancontrol remove
followed by sudo update-rc.d fancontrol defaults to get it to start correctly at boot time.

[Anbech]

NEVERMIND! got to work! :D

it was kind of a hassle and had to change some things inside "/usr/sbin/fancontrol", "/etc/fanctrol", and some other stuff... :)

ive packed down the files if anyone else should encounter the same, with the files as they should be to work with CPU and GPU (nVidia) fans. my gpu fan is connected to the motherboard, but it might work if its connected to the gpu too..

i can NOT guarantee that itll work for others, but it _should_ just by editing the "/etc/fancontrol" file, to your needs.

btw, remember to sudo chmod 755 the files after they are extracted to their right place.

oh, and for starting the process i have to use "sudo fancontrol &" and for stopping it "sudo /etc/init.d/fancontrol stop" .. kinda weird i know, but it works :)
still havent figured out how to make it start upon ubuntu startup (yet a thing to be made) :)

the package can be downloaded here (permanent link) :
fancontrol.zip (http://djanbech.com/ubuntu/fancontrol.zip)

hope some of you can use it too auto adjusting both cpu and gpu (nVidia) fans.
cheers

That doesn't show any fan sensors, which most likely means that there are none. Many laptops don't have them, or at least, nothing is detected by lm-sensors. I'd suggest searching for your specific brand and model, hopefully someone else had the same problem and got it fixed.

I've looked and I can't seem to find any way to fix the problem. The laptop I have is an HP Pavilion dv6.

Right, I am going to post some suggestions in the other thread.

Got the fancontrol working really nicely. This old Asus A7V880 MB gives the CPU fan only some minimum or then maximum and nothing between those. This is my /etc/fancontrol setup for Athlon XP 2800+ based machine running Ubuntu 10.04 32bit:

# Configuration file generated by pwmconfig, changes will be lost

MINSTART= hwmon0/device/pwm1=101
MINSTOP= hwmon0/device/pwm1=100
MINPWM=hwmon0/device/pwm1=90

CPU temp keeps at 54C at idle and the fan is at 1380RPM. Under load the CPU temp rises up to 57C and then the fan is at 1750RPM. That's the highest temp which I got currently. With the ASUS Q-Fan control the CPU fan is at 1200RPM until some configured limit has been reached. Then it pumps the fan to maximum speed up to something like 2600RPM and that I can also hear :P

[geronimo66]

Hello,
does anybody knows, how to enable fancontrol, if pwm says "no, there are no sensors"?
I think, most users without working fancontrol suffer at this point.

I got this issue with a Toshiba Satellite. sensors just detects the thermal sensors, managed by coretemp, but no fan.
thanx for replying

[Shaktijar]

Hi,

I'm wondering.. does the script start every time the system boots up? How about surviving a hibernation? I think these are general init-script issues... or?

cheers
Actually, my fancontrol, for instance, doesn't survive a hibernation or suspend.


Have fan.

[Wizzard]

Hi. Is it possible to preserve the fan speed after stopping fancontrol service? I would like to let the fan speed constant after rebooting the computer.

Now when I reboot the computer, after shutdown of all services, the fan start to spin very fast, like without fancontrol. In Windows, I use speedfan and it preserves the fan speed after its shutdown.

Hello All,

I just upgraded to Ubuntu 13.04 64bit from Ubuntu 12.10 64bit. Fan control was working perfectly in Ubuntu 12.10 but now when I do sudo pwmconfig it says "hwmon2/device/pwm1_enable stuck to 2, Manual control mode not supported, skipping hwmon2/device/pwm1.
There are no usable PWM outputs." Like I said it was working like a dream but after the upgrade not working? It would be nice to get this working, I use max fan on my T61 when editing music or other cpu intensive stuf and it really keeps the lappy cool. Anyone have any ideas how to get this working??

Cheers,

Singtoh

[guilhermemtr]

don't give them ideas :roll:

Nowadays most of the SO's just shutdown if the critical temperatures are reached :)

It has already happened to me, but with my laptop, not because of the fans, but because of some accumulated "thrash" inside of it.
(sorry for my english)

[Singtoh]

Hello All,

Well I got it going after looking at the How to fancontrol page. I was using this:"For example, in Ubuntu 8.04 (Hardy Heron), add the following to /etc/modprobe.d/options: options thinkpad_acpi fan_control=1" from that page. Now I am using this:"For Debian Squeeze (testing) create /etc/modprobe.d/thinkpad_acpi.conf with: options thinkpad_acpi fan_control=1 and install the package thinkfan" from the same page and it works just fine. I am using Ubuntu 13.04-64. I still have fancontrol installed along with thinkfan but I think this file is what fixed it for me:/etc/modprobe.d/thinkpad_acpi.conf and inserting this:
options thinkpad_acpi fan_control=1 into that file.

Cheers,

Singtoh

If you are not getting all your sensors identified, you may have a newer motherboard chipset with the repo version of lm-sensors cannot see.

To get the latest version of lm-sensors go to lm-sensors.org and click on the Devices Support Status link

In the blurb at the top of this page you will find a link to download the latest version of sensors-detect. It is a standalone script so no compiling needed.

Once downloaded, make it executable and run it e.g.


sudo ~/Downloads/sensors-detect

With any luck you will then find your sensors and be able to run pwmconfig.

With the correct chipset sensor module defined I had to go back to the Devices Support Status page and grab the source code for the module, a quick and easy make & sudo make install & sudo modprobe nct6775 got me up and running. (It was nct6775 in my case, may be different for you)

This worked for me with an Asus Z87M-PLUS mobo with i5 core 4670K processor
