Before I installed SL my computer was dead silent. After I installed it The fans got really loud. It sounded like a cd in the cd drive.(There wasn't as cd in the drive) I just reinstalled Leopard and the fans are still making noise. Its more like a low hum but in a quiet room it is really annoying. Is there anything I can do? Have other people had this problem? Also after installing SL my computer temperature is around 60c just surfing the internet when before it was 35c. The internet also turns itself off? Should I call Applecare and tell them what is going on?
