I've got a PowerBook G4 15" laptop. I'm pretty sure internal fans used to be kinda loud when they kicked in. Except I haven't heard them in a while, which leads me to wonder if they've stopped working. Anyone know of any kind of software that would let me manually switch them on and off, or any other way to determine if they're definitely dead? Thanks for any help.
Got a tip for us?

Looks like the fans are currently not spinning. Any idea as to when they should start, if their not dead?
Thanks 
So, based on this I managed to get the internal temperature of my powerbook up to over 140 F. The left fan is spinning (currently 1848 rpm), but the right is not (0 rpm). I guess this means I need a new right fan? Or is it possible for one fan to kick in without the other turning on?

The laptop continues to work just fine with no fan noise.
