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
(http://cl.ly/6FVD)
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 (http://cl.ly/6GFm) 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.

Your CPU won't be at 93% if you're doing "absolutely nothing". Use Activity Monitor to see what's consuming system resources.
...the fans suddenly kicks in and increase to a 'stunning' 3000RPM.
3000 isn't "stunning", as the fans can spin over 6000 rpm, when needed. There's nothing wrong with your MBA. You just need to determine what app/widget/process is placing demands on your CPU, which increases heat and causes the fans to spin up.
