Is the FAN running only under Ubuntu or with other OS too? Maybe the notebook need to be opened and cleaned...?!

Maybe its possilbe to set the temperature when the FAN should start to run to a higer value in the BIOS. This can be dangerus, when the FAN doesen't start early enough and the notebook gets too hot.
