Hey All
I just got back from school and my mom's computer is making this loud, obnoxious noise. Its a 733Mhz Quicksilver G4, stock except for a BTO ZIP drive and an extra 512MB DIMM. Listening to the computer I decided that the noise was coming from the fan mounted next to the CPU heatsink. When we pulled the computer out of its shelf on her work desk, I found that the (intake?) holes were thoroughly clogged with dust. We vaccuumed that stuff out and started up the computer but its still making the noise.
My guess is that the fan is thoroughly shot. It turns itself on and and off intermittently. I touched the CPU heatsink to see if it was overheating. (The OS doesn't report temperature anywhere, does it??) It was hot to the touch, such that I could put my hand on it for a few seconds but I could tell that it was too hot to keep my hand on for much longer. Is this too hot?
I'm telling my mom to take it easy until we replace the fan. Does anybody know what part number it is? It looks difficult to get to because its mounting screws are behind the heatsink. Should we take this to a pro or can i DIY? I'm not faint-hearted with electronics and I'd prefer to save the money if possible. Apple support web site didn't offer much...If I don't get any ideas I'll probably just pull the fan out and go to the store and find the nearest spec'ed fan to it.
Thanks,
Mark
