Sometime around kernel 2.6.18 I noticed the fan wasn't running anymore, at the time I found it a relief because previously it was running constantly and it was kinda noisy. So I didn't really think anything of it until a heavy load just sorta made my whole system stall and run at extremely slow speed. Top showed a 99% cpu useage by a program called kacpid. Googling gave me the following answer from linuxquestions.org:
http://www.linuxquestions.org/questions … p?t=213429
So I installed acpi and acpid but I still got the following:
$ modprobe fan
FATAL: Module fan not found.
$ modprobe thermal
FATAL: Module thermal not found.
I tried Lm sensors, I got the following detected:

and the fans still aren't working. I'm not sure what to try next, can anyone please tell me what to do to get my fans working again? I have a HP pavilion a305w desktop pc w/ a trigem motherboard if it helps the motherboard specs are here

only thin i can suggest is to add those modules to your mkinitcpio.conf if they aren't already ...
and or boot from the falback img adn try again

Well something is wrong, I'm using knoppix and the fan works fine here. so I run 'modprobe -l fan' and I get this output:
/lib/modules/2.6.19/kernel/drivers/acpi/fan.ko
but then I look in /dev/hda3/lib/modules/2.6.20-ARCH/kernel/drivers/acpi and I see no module called fan.ko is there another package I need to download for this module?

Well my first thought was to just copy the modules into /dev/hda3/lib/modules/2.6.20-ARCH/kernel/drivers/acpi but modprobe failed to load the modules anyhow, looks like they have to be compiled as modules from the kernel (and frankly I see no reason why they would be compiled otherwise) I'm starting to think this is a bug in the arch kernel configuration.

Thats exactly what it was, I recompiled the kernel with ACPI suport modules compiled as modules and got the fan working again. I believe I should inform whoever maintains the stock arch kernel of this as I believe it is compiled incorrectly.
