wow. i'm very surprised that ya'll are folding on an air. it seems the fans come on my air when watching a youtube video.
Might as well right, the fan is pretty much on 24/7 at 6200RPM when I'm at home lol. The only time I see 2500/4000 RPM fans is when I'm at the library or in class. At home, I have music blazing in the background so a little fan noise don't matter.
