fans?

[Mike S <michael_six@users.sourceforge.net>]

I have been reading posts back and forth on fan control in the ppc64 
kernels.  I am in no way on that architecture (you lucky ducks) but this 
has intrigued me, is it a bad thing that my 2 fans are always going in 
this G4?

As I am learning this (linux) how would I test the internal temperature, 
rather than physically sticking a thermometer in there for a few hours 
of use?  My girlfriend is often complaining that the fans are too loud 
when I am in linux, I don't notice much difference, but if this is 
something that can/should be tweaked, can someone point me to a url 
somewhere or explain to me how this should be done?

I am working on a self compiled 2.6.11 upstream kernel, but when I just 
read the post about from Shyamal I think saying that his fans were going 
full blast, and if mine are I wouldn't know the difference, so I just 
thought I would ask.
