Thanks for your reply, Jim. The fan turns on the moment I plug it into the wall, though. (It only started doing that about a month ago as far as I can tell.)
So it's definitely meant to do that before I even press the power button?

As iMac G4 cooling air enters from the bottom of the case and exits at the base of the chrome stalk, it acts as a vacuum cleaner. If you take it apart and get rid of all the dust bunnies and crud buildup on the fan blades and in the entrance and exit ports for air, you'll get a quieter iMac. On the other hand, perhaps the fan bearing, which is probably getting close to 15 years old, is wearing out and adding to the noise. If you do take the case apart, be sure to remove the old thermal pad material and replace it with thermal paste so that heat generated by the cpu and gpu can be piped up to the fan properly. Good luck!
