if it was the fan it wouldn't be in short one second spurts separtated 
by two seconds of quiet right? a fan would be doing it for longer 
periods right?
it does seem to be connected to high heat...but i think getting very hot 
is typical for tibooks and the noise doesn't seem to be coming from the 
area where the fans are. as a matter of fact i am not sure i have ever 
heard the fans run...maybe they don't and that is the reason ??? i guess 
i could put some tisue paper in from of the holes and see if the air is 
stiring.
