Hey guys, I have a G5 Powermac 2nd hand for 2 or 3 years now and i noticed its really noisy. the sounds coming from it i assume only the fans can make and its really annoying. it drives me crazy when nothing else is on it my room its like its taunting me or tryna tell me somethings wrong with it. Not only is it annoying but it also going to hinder my plans to start recording vocals for my music since i'm pretty sure the mic is gonna pick it up. the fans aren't even on full blast there just loud. What's goin on here, what should i do?
