Thread: How do I control CPU fan?

  1. #1

    Default How do I control CPU fan?

    I've done quite a bit of searching on this. My CPU fan is running at full speed all the time. This is an HTPC, so sound is a major concern. I see lots of people with specific questions about making fancontrol do what they want it to do, but I don't find any how-to to get it running from zero on OpenSUSE.

    My motherboard is an old Asus A8N-SLI Deluxe (nForce4 chipset)
    I've installed the sensors package and run sensors-detect.
    At the least, I'd like help on what to do from here. At best, It would be great if somebody could give full instructions on how to get fan control on OpenSUSE.

    Hi
    So what about the setting of the cpu frequency;
    Code:
    cpufreq-info

    Hi
    So what CPU on the system? If AMD, is the powernow-k8 module loaded?

    I don't even think it's installed. I searched the software management thing for K8 and it found nothing.

    thing for K8 and it found nothing.
    Hi
    It's a kernel module;
    Code:
    su -
    modprobe powernow-k8
    exit
    cpupower frequency-info
    What CPU are you running?

    Hi
    OK, then the module should work to set the frequency and should spin down the fan some.
