My laptop is excessively hot and is severely under-clocked. I have noticed that while running Ubuntu 11.10 my fan speed will never reach its max. When I restart my machine the fan speed will go MAX, until grub loads the kernel and then fan speed will be dangerously slow once again. If I follow these steps pwmconfig will complain: There are no pwm-capable sensor modules installed.

What do I do? How do I speed up my fan?

There is a thread on the ubuntu forums - it gesta a little off topic - ubuntuforums.org/showthread.php?p=11428638 See the last two posts. Update bios or see this link techytalk.info/… I do not have your hardware to test that on, perhaps someone else will have a better suggestion now we know your hardware. – bodhi.zazen Dec 10 '11 at 1:03
@bodhi.zazen my laptop is already extreemly under-clocked. I want to fix he root of the problem, the slow fan. – Hank Dec 10 '11 at 1:04
Check your bios when you boot to see if there is an option to increase the fan speed. Otherwise the thread on the forums I gave you seems to be your exact acer model and has several suggestions. Otherwise we will have to wait to see if someone with your hardware chimes in. Or you could file a bug report. Good luck. – bodhi.zazen Dec 10 '11 at 1:17
@bodhi.zazen See that is exactly the problem. The fan speed IS maxed when the bios is loaded, it drops after grub loads the kernel. Also i have reported this as a bug in Ubuntu, and it has been accepted but is currently low priority... – Hank Dec 10 '11 at 1:18
OUCH !!! Probably a kernel bug then, the second link I gave you is the best I could find on your acer. – bodhi.zazen Dec 10 '11 at 1:19
