Can anybody please suggest a quiet fan system to replace the very noisy fan in my new G4 800 mhz eMac? I upgraded from an iMac and was totally unprepared for the background noise in the new machine, which comes from the fan. Since I do a lot of audio recording, I need to fix this problem. Any help would be much appreciated.

unfortunately, as speeds increase... so does heat output usually so fans become noisier and such... not sure if you will find a quite fan that will cool sufficiently but... if you want quiet computer for recording... consider building some type of isolation box for computer for put up some type of temporary wall or distance recording area more from computer

Fan noise CAN be reduced. Methods include replacing the stock fans with low noise equivalents (need to be careful and make sure internal case temperature does not increase), isolating your computer in a (custom) isolation box (remember to ventilate it using low noise fans), putting the CPU in a separate room if you can, and finally....

Consider buying a special complete fan replacement kit, like the one made by verax (see veraxfans.com) I have not tried this last option, but the G4noise.com site has a lot of dicussions where people have had success, a few have not. This of course will void your warranty so be warned.

I have my G4 DP 867 in an isolation box with fans in my studio. I still want it quieter, but not sure if I will risk the Verax kit or not. These are all ideas, it's your risk, I am not responsible for the results.

Fusion Head,

Your comments are so out of line! Put the CPU in a separate room! Are you stupid! This is not logical, welcome to the real world.

Thank you Cheama for your respectful consideration of my suggestion :-)

Personally, I could not consider putting my CPU in a different room, that is why I built the sound isolation cabinet for my G4 (3/4" plywood, lined with thickest carpet underlay I could find, grid of 1" holes in bottom near front of cabinet for G4 to "suck" in air, then 2 low noise Papst fans mounted in the back panel to "suck out" the hot air).

My solution works pretty well, but I have indeed read of professional studios putting all their CPUs in different "server" rooms and using various methods of extending video and keyboard connections to their desks. That IS a practical real world solution, just one that may not be practical for home-based systems.
