[Bug 22336] Re: laptop overheats when performing CPU intensive tasks.

[Chris Moore]

I run ubuntu and debian on the same laptop.  ubuntu crashes if I use the
CPU for more than a few minutes at a time, debian doesn't.  I can tell
when ubuntu is about to power down because the fan in the laptop starts
running at full speed continuously, making quite a loud noise, whereas
in debian the fan alternates between full speed and something slower.
It's as if debian is noticing that the fan isn't able to cool the CPU
enough and does something to make the CPU generate less heat, whereas
ubuntu doesn't.

What are the significant differences between ubuntu and debian with
regards to the CPU speed management?  Hopefully I can find a way of
either reproducing the problem in debian, or making it disappear in
ubuntu - but what should I tinker with?
