HOW TO: Install and configure lm-sensors

[Shekibobo]

The only thing my sensors detected was the intel-chipset cpus:

josh@ubuntu:~$ sensors
coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +52.0°C  (high = +85.0°C, crit = +85.0°C)  

coretemp-isa-0001
Adapter: ISA adapter
Core 1:      +54.0°C  (high = +85.0°C, crit = +85.0°C)

And it automatically added the lines of code required:

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

Driver `coretemp' (should be inserted):
  Detects correctly:
  * Chip `Intel Core family thermal sensor' (confidence: 9)

I will now generate the commands needed to load the required modules.
Just press ENTER to continue: 

To load everything that is needed, add this to /etc/modules:

#----cut here----
# Chip drivers
coretemp
#----cut here----

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

I apparently didn't need to do anything else because the sensors command seems to work just fine. I just don't get much info. Might be because I'm on a laptop, though.

Is anyone using lm-sensors with the Intel Core i7 965 Extreme? I'm seeing temps of about 65C at idle with lm-sensors. Is this accurate, can I trust what lm-sensors and coretemp are reporting?

[cyberkost]

I'm not using i7 965, but I read that:
1) many temp sensors return not the temp, but delta to critical temp. So, the reading is a function of how correctly the critical temp is set in the BIOS
2) lm-sensors do a bit of math that is sensor specific. The formulas may be wrong, chances of that are higher for newer/rarer hardware.
Can you check temp in a Windows environment?

[o0Chris0o]

ok I installed lm-sensors and everything. I don't think its listing right. Please have a look.

any ideas? I am trying to get the temperatures/fan speed for my Motherboard, Processor and 4 cores for conky. My computer information is in my sig.

[miegiel]

@o0Chris0o, the calculations of the sensor output are probably wrong. If you're worried that there might be something wrong with the PSU go to the BIOS and check the voltages there. In any case at 4V your CPU would have already died.

I have an Intel Core i7 on a Gigabyte GA-EX58-UD5 motherboard and am running Ubuntu 9.04. I've been trying like crazy to get lm-sensors to work but seem to be failing miserably. Could someone please tell me what I'm doing wrong? I first installed lm-sensors through the repository, ran sensors-detect.. had not luck, then I installed it from source, same thing happened again. Here's the output I get from running sensors-detect:

# sensors-detect revision 5666 (2009-02-26 17:15:04 +0100)
# System: Gigabyte Technology Co., Ltd. EX58-UD5

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): 
Silicon Integrated Systems SIS5595...                       No
VIA VT82C686 Integrated Sensors...                          No
VIA VT8231 Integrated Sensors...                            No
AMD K8 thermal sensors...                                   No
AMD K10 thermal sensors...                                  No
Intel Core family thermal sensor...                         Success!
    (driver `coretemp')
Intel AMB FB-DIMM thermal sensor...                         No
VIA C7 thermal and voltage sensors...                       No

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): 
Probing for Super-I/O at 0x2e/0x2f

Trying family `VIA/Winbond/Fintek'...                       No
Trying family `ITE'...                                      Yes
Found `ITE IT8720F Super IO Sensors'                        Success!
    (address 0x290, driver `it87')
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor'...                   No

Trying family `ITE'...                                      No

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We have to read from arbitrary I/O ports to probe for such interfaces.
This is normally safe. Do you want to scan for IPMI interfaces?
(YES/no): 
Probing for `IPMI BMC KCS' at 0xca0...                      No
Probing for `IPMI BMC SMIC' at 0xca8...                     No

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (yes/NO): yes
Probing for `National Semiconductor LM78' at 0x290...       No
Probing for `National Semiconductor LM79' at 0x290...       No
Probing for `Winbond W83781D' at 0x290...                   No
Probing for `Winbond W83782D' at 0x290...                   No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no):

Module i2c-i801 loaded successfully.

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

Driver `it87':
  * ISA bus, address 0x290
    Chip `ITE IT8720F Super IO Sensors' (confidence: 9)

Driver `adt7473':
  * Bus `NVIDIA i2c adapter '
    Busdriver `nvidia', I2C address 0x2e
    Chip `Analog Devices ADT7473' (confidence: 5)

Driver `coretemp':
  * Chip `Intel Core family thermal sensor' (confidence: 9)

Do you want to overwrite /etc/sysconfig/lm_sensors? (YES/no): 
Copy prog/init/lm_sensors.init to /etc/init.d/lm_sensors
for initialization at boot time.
You should now start the lm_sensors service to load the required
kernel modules.

Unloading i2c-dev... OK
Unloading i2c-i801... OK

In hardy I'd say add

# lm-sensors for Gigabyte GA-EX58-UD5
it87
coretemp

too the end of your /etc/modules file. But your sensors-detect out put is different from mine so possibly stuff has changed ? Do you have a /etc/modules file?

[Greenwidth]

Thanks for the HOW TO!
I seem to be getting conflicting results though from SMBus and ISA.. Not really important but how do I stop SMBus reporting? Remove it from etc/modules ?

Thanks for the HOW TO!
I seem to be getting conflicting results though from SMBus and ISA.. Not really important but how do I stop SMBus reporting? Remove it from etc/modules ?

In short yes, or put a # at the start of the line.

Running sensors-detect again and checking the "confidence" of the different sensors might be wise too.

Good plan - SMBus scores a 5 and ISA gets 9 so i'll go with that
