Hi,
Thank you for your help, here is the issue I encounter : I've installed Ubuntu 12.04 (clean install, 64 bit version) and my laptop's fan spins all the time. Even when the laptop is idle, or in a minimum usage. Here is my configuration : Dell Vostro 3450, CPU i7-2640M @ 2,8 Ghz, 6Ghz Ram, Video card AMD Radeon HD 6630M and Mobile Intel HD Graphics.
I have also installed proprietary AMD drivers, but not any change.
This is very annoying, since fans make a lot lot lot of noise.
Hope someone can help me
