not Snow Leopard, but Leopard. If you have iStat pro installed, what's the temperature usually at? I installed Snow Leopard way back and I'm really regretting it right now since my MacBook hovers between 65-70 degrees Celsius. I don't remember it being this hot in Leopard. Also, all I'm doing right now is web browsing and Adium and my fans are spinning and my MacBook is hot. Anyone have any insight here?
