Mmmmm... certainly very interesting 8-) I just thought that the freq.
scaling was a "real" scaling XDDD Nevertheless, it is cool.

Yep, luckily, the fan is very quiet (for a laptop fan :) But
nevertheless, I wonder why it is running most of the time :-?
I think I will try MacOSX with some performance/usage monitor, and I
will watch the cpufreq as well, to see when the fan kicks in/out and try
to compare with Linux.
But that will be after exams 8-) Me, I am about to die in a few weeks!
:)
Thanks for the answer, Michael. I will check on this sometime soon and
perhaps, I will even come out with something! XXDD :)
