Before installing ML, I installed an SSD and moved my HDD to an Optibay-like holder. I'm finding that my MacBook's fans are spinning a lot more than they did in Lion. It seems that the fans cannot slow down when needed, they seem to spin up when required but then just stay at a high rpm, even when the MacBook is idle. If I put the Mac to sleep for a few seconds, and waken it as soon as the fans have stopped, they are back at 2000rpm, which proves that the cooling is not needed. Is this a ML problem or maybe a hardware problem? A few stats: Start from cold boot: HDD 25C CPU 65C Fans 2000rpm Using Safari, Pages and Numbers: HDD 35C CPU 75C Fans 3800rpm (can go up to 6000rpm) Help!
