I've got a Power Mac G4 MDD that I've had for about 6 years now, and it's just as noisy as it's ever been. Interestingly enough, as of late, it seems to be faster on the Internet than it was before (with both Safari and TenFourFox for the PowerPC 7450) and I feel like I can put this machine to use, especially for a few older games that I've got. Problem is, this computer is noisy. I used to have no issue with it, but in recent times I've become less tolerant of the noise, now that I've had quiet main computers for a while now. I know Apple offered a 360 watt (or thereabouts) power supply that was quieter and more reliable than the original 400 watt PSU, but funny thing: I've already got that "quieter" 360 watt PSU (just makes me wonder how much noisier it was before). What can I do to make the machine quieter? Are there any programs that I can use to slow down the fans a little, or is there some kind of hardware trick that I can use?
