Just got the silentmaxx 550 PSU and I gotta say this thing is DAMN quiet....I can't hear it at all, not even with my ear next to it...I was actualyl worried that the fans weren't working, but I could feel the hot air comming out....I just wanted to ask if its normal for a PSU to get really hot....when I shut down it gets so hot I can hardly touch it.....its just a little more touchable when its on....anyone had a similar experience with the silentmaxx PSUs?
