Yes, I know for certain because as it came with windows xp installed, I could see that when I booted it up, the the laptop started with fan on, later after some type in windows, it turned off. If I did some work with disk or cpu load, it turned on again and later turned off. I know this only because the noise it did when it was turned on. :) Another think I noticed is that I could see in /proc/acpi/fan/ that I have three fans but only fan 1 is on the other two are off. Is it possible that acpi would never turned them on??

I'm worried because I thought that fc2 could be misusing the fans and this could burnout my laptop. Also, as the fan keeps on all the time, my battery time suffers a lot :( > Does the system slow down when on battery or after running a while? > This may indicate that the CPU is throttled for thermal control. > I didn't notice any slow down. I also could not get throttle info from /proc/acpi/processor... it says not supported. This may be caused because I'm using the 2.6.5 kernel? I'm downloading 2.6.7 to see if I get better support. > Are there other problems or glitches with the system? CPU's do crazy > things when they overheat.

I'm working on it right now, and I hope it doesn't have any problem. Can I do anything else to get more control over fans? Thanks Erik.
