Hi,
I just received my MBA 11.5" 1.4Ghz and 4Gb or RAM yesterday morning, and after few hours of working with it, I also noticed the little buzzing noise coming from the fan, at the left of the keyboard.
I haven't installed any software yet, it's still with what it comes. I only installed iStat Pro's Widget to check how fast was the fan spinning, and indeed it's at a constant 2000rpm.
What's bothering me is that if the fan is at 2000 rpm, it should be almost noiseless, but if the room is quiet, I can clearly hear the buzzing little noise.
I can't compare it to any other laptop right now, but I can say that my last Macbook black was quieter when the fans were spinning at the same speed than the MBA.
Any suggestion how to check if the fan of my MBA is not right?
Thanks!
Cheers
