Absolutely! My fan runs continuously. Had the good old display failure (2002/800/Combo) accompanied by a cheerful AppleCare "logic board replacement". Fan runs all the time. iBook much cooler. Unfortunately, I had done lots of other stuff like wipe and clean install Panther before I noticed continuous fan. Never thought about the service proximity being coincidental with the fan running.... I also have a voltage leak which is easily felt by sensitive skin. And surprisingly, the battery life seems OK, but I'll bet it would be better without the fan and stray voltage. Kevin
