Hi MacRumors, just recently got my MacBook Air Ultimate 13" and so far I love it. It's small, mobile, awesome SSD and plays Starcraft II pretty good with its 320M. I do have a serious problem though, which I just got recently. Please bear in mind that I just received it. Sometimes when doing absolutely nothing (CPU idle at 93% and 55° celsius) the fans suddenly kicks in and increase to a 'stunning' 3000RPM. Then after a while, it slowly runs down to 2000RPM but after a few minutes, it goes up to 3000RPM again. As I write this, it's currently 2900RPM So I just sat it there, did not touch it at all. Saw how it went from 3000RPM to 2000RPM then back up to 3000RPM again. Here is a SS of my processors. Is there something I can try to do, any magical tricks - like PRAM or SMC resetting? I really don't want to send it back for a repair, as it's my primary school and work computer. It would be hard for me to even miss it for 14 days. I hope you have tried something similar and found a fix to this problem. Thanks in advance.
