    How do I change my CPU fan speed?

    Greetings,

    In Windows (which I can happily say that I no longer have) I had a program called SpeedFan, which monitored the temperatures of my hardware and also my fan speeds. In Ubuntu I monitor my temperatures and fan speed through and AWN applet called Hardware Sensors; however I cannot find a program to change the fan speed. I think that it is just running at full speed in Ubuntu, I'm sure it was slower in Windows.

    If anyone could help, that would be great.

    Thanks,
    Arachan.

    How To Control Fan Speeds in Ubuntu

    Check your BIOS as well.

    install ( htop ) run it and see if something is wrong first

    open a terminal type in, htop it tells you how to install it

    type htop see what is running to make the fan run fast

    i use a flash chat and it hits my cpu at 80to 100%

    depends on what browser i use i find the 1 that only goes to 16% and use it

    hope this helps

    Greetings,

    Thanks for the swift replies. I tried fancontrol but I got an error:

    Code:
    Loading configuration from /etc/fancontrol ...
    Error: Can't read configuration file
    I had a look and there was no file. How would I make/get one?

    I tried the tuxtweaks link and go up to the step:

    Code:
    sudo pwmconfig
    Where I got the error:

    Code:
    /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed
    Even though I added the one that:

    Code:
    sudo sensors-detect
    found. How do I get it to recognise my fan? It's just the basic HSF for an Intel E2180.

    I also tried htop, but I couldn't see anywhere in it to manually change fan speeds. Could you point me in the right direction for that?

    Thanks,
    Arachan.

    Re: How do I change my GPU fan speed?

    Greetings,

    On a semi-related note, I noticed that my HD2600 fan is running at 100% all the time. How would I slow that down?

    Thanks,
    Arachan.

    Greetings,

    I discovered the command

    Code:
    aticonfig --od-gettemperature | grep Sensor | awk '{print "GPU: " $5 "C"}'
    displays the GPU temperature. The command

    Code:
    sudo aticonfig --pplib-cmd "set fanspeed 0 20"
    sets the fan speed at 20% (what I run it at now).

    I use something called acpitool. I don't remember where I found it or why the others things I tried didn't work.
