    "Found unknown Chip", but in the documentation I can see, that the EMC2103-2 sensor is supported. Does somebody know how to force sensors, to use the EMC2103-2 Sensor? I'm 100% certain that it is the EMC2103-2 sensor, because I use it under windows as well.
    What version of lm-sensors do you have? I had trouble with it finding one of my sensors until I installed the latest. Sensor emc2103 needs kernel 2.6.32 or newer. What happens when you install the emc2103 module?

    Code:
    sudo modprobe emc2103

    Re: HOW TO: Install and configure lm-sensors

    I use 3.2.0-24-generic-phc. I can install/load the emc2103 -module @ startup or with modprobe. It even shows up with lsmod, but nothing happens. Or is there some way I can use it? Maybe its somehow possible to manually edit the cip IDs so that ID ID 0x4501 is recognized as emc2103?

    The problem is just that my notebook really heats up, so I want the fan to run faster. Even @ 80C it just runs with 50% speed.

    What's the output from the sensors command? Sorry, can't help with fan speed. Maybe someone else can.

    Did you look at the lm-sensors FAQ?

    Re: HOW TO: Install and configure lm-sensors

    @sebl Did you check your fan for dust? (In the category "Answers that are not related to lm-sensors".) With notebooks you often only need to lift the keyboard to reach/clean the fan. The heatsink can be dusty too, but it's more difficult to reach. Use a new/clean paintbrush, old toothbrush or compressed air (you can buy it in spraypaint-like cans).

    For the CPU temperature you can ignore the acpitz-virtual-0 temps, I've found them not to be accurate. It's the coretemp-isa-0000 temps you need to keep an eye on.

    My netbook went over 70C a few days ago. In the sun, air temps just under 30C And I didn't even make the machine work that hard.

    Exclamation Re: HOW TO: Install and configure lm-sensors

    I am a bit confused. I feel like I installed and setup lm-sensors on Ubuntu 12.04 and Arch Linux in exactly the same way, but running sensors gives me much more output on Arch than it does on Precise. It seems like something is not working on Precise or I have done something wrong.

    Also, when I try to start or restart service module-init-tools, it just immediately replies that it is in status "stop/waiting". My guess is that this is where my problem lies.

    Here is my output on Ubuntu 12.04:

    PS - Never mind. I need to go to post 1 and work my way through all that beginning info. But, I didn't need to do anything like all that on Arch. Sorry.

    Re: HOW TO: Install and configure lm-sensors

    See the preceding post. Now, I have followed post #1 instructions and I get the same results. It seems to find another sensor, but it does not include it in the stuff it says to add to /etc/modules. It only says to add coretemp, which is already there.

    Just press ENTER to continue:

    Driver `to-be-written':
    * ISA bus, address 0x290
    Chip `ITE IT8728F Super IO Sensors' (confidence: 9)

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

    Note: there is no driver for ITE IT8728F Super IO Sensors yet.
    Check http://www.lm-sensors.org/wiki/Devices for updates.

    To load everything that is needed, add this to /etc/modules:
    #----cut here----
    # Chip drivers
    coretemp
    #----cut here----
    If you have some drivers built into your kernel, the list above will
    contain too many modules. Skip the appropriate ones!
    So, it finds a "Chip `ITE IT8728F Super IO Sensors' (confidence: 9)", but then says there is no driver for it. Apparently, the driver is found and used in lm-sensors on Arch Linux. Is there a way to find and load this driver on Ubuntu?

    Also, there is a module it87.ko in my drivers folder, but if I try to modprobe it, it responds that it does not exist. ???

    Tim

    PS - Later [SOLVED]

    Downloaded newer driver from http://khali.linux-fr.org/devel/misc/it87/
    Ran make, make install, modprobe it87
    sensors now returns all the info expected

    Re: HOW TO: Install and configure lm-sensors

    Recently I got the feeling that lm-sensors (or coretemp) CPU temperature readings are way off.

    I'm currently running kernel 3.2.0-30-generic and 3.2.0-31-generic on two different machines. My older Core2 machine ran Linux Mint 9 before and temperatures were well below 40C when idle. Now they are in the 50s.

    On my new machine with an Intel 3930K CPU I also noticed higher temperature readings, but I can't remember exactly when it started (meaning which kernel update or lm-sensors update produced the problem).

    Anyone noticed something similar? I believe the CPU temperatures reported by lm-sensors are some 15-20C higher than the actual temperature, or at least how the BIOS reads the temperature.

    Re: HOW TO: Install and configure lm-sensors

    Hi guys. This is my konsole output

    Code:
    # sensors-detect revision 5984 (2011-07-10 21:22:53 +0200)
    # System: LENOVO 20091 (laptop)
    # Board: LENOVO Base Board Product Name
    
    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): y

    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): y

    Trying family `ITE'...                                      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): y
    Probing for `National Semiconductor LM78' 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.
