In my case, rebooting also makes it stop for a while. I'm running 10.2.8 with the battery update. I'm not sure that it might be a static issue; one time (before I found our old humidifier) I got a static zap off the iBook & the fan came on immediately. Ironically, I suspect that Jack Rodgers & other folks in South Florida probably don't much of that -- there's plenty of humidity to keep the static down.

It sounds slightly like the CD drive spinning, but louder. When it comes on and stays on, you can feel it pushing air out the vent in the hinge. I can get the fan to come on momentarily by doing something silly like asking iMovie to render dozens of transitions at the same time. :-) -- Larry Kollar k o l l a r @ a l l t e l . n e t "The hardest part of all this is the part that requires thinking." -- Paul Tyson, on xml-doc
