Hi list,

since i dont't know where else to ask this question i figured i might as
well ask it here.
i'm running gentoo on my tibook 550 (powerbook3,3 that is in
kernelspeak) and noticed that with a 2.4 kernel as well as under macos
the fan hardly ever kicks in, even when the computer gets quite hot
while with the 2.6 kernel the fan wouldn't stop running.

while this aproach is probably bying me some more lifetime for my
computer, it is seriously annoying not to have at least an occasional
moment of silence when sitting in front of the box.

i already tried searching the kerneltree for suspicious expressions like
"fan.*control" and such but so far without success (meaning i found only
acpi-related stuff).

can someone please give me a hint where else to look or even where else
to ask this question? any help is appreciated!

thanks in advance and best regards,

alexander
