Hi all. I tried to search for this topic but I could not find it during my search of forums. I hope I posted this topic in the right place. I recently got an old MDD Dual 867mhz G4. The computer itself runs perfectly but the fan is really loud. I have read that this is was one of the bigger problems when these first came out a couple of years ago and that Apple did have an exchange program for these loud fans/power supplies. Now obviously they probably don't have this exhange program going on anymore. I'm not that versed as far as what kind of fan I would need. There are so many out there to choose from. Even something half as quite as the stock power supply/fan would do. Does anyone have any recomendations as to what power supply/fan I should get and where to buy it from? Thank you very much!!
