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?
