My MacBook Air makes a humming/buzzing sound ALL THE TIME

I've had my Air for two weeks now. At first, it didn't do this but now it gives off a distinct buzz constantly. And no, it isn't the ventilation. It does this even after having been switched off for hours. Any idea why this is and what I can do to stop it?

MacBook Air, Mac OS X (10.5.2)

um i don't really know what's going on in here though. i bought a penryn MBP a few months back after apple released a hardware revision. when i'm playing cpu-intensive games such as ut2004, fan rotates at high speed at around 5500 RPM and makes noise, but other times everything is fine and silent.

are you guys complaining that fans make annoying noise when you run processor-intensive applications?

In my case, the fan is touching something when spinning, and that's why it's buzzing, it won't spin faster then 2000 rpm, and the processor is overheating, one core is shutting down, etc.

I also have this issue. My MBA was 2 weeks old and running just fine and one day, the fan started rattling. I found that the fan would be ok but will start rattle after i pick up the MBA. This happens on both MacOS and XP. I then installed a program monitoring the fan speed and it will show a drastic fanspeed decrease (5500rpm down to 2500rpm) when the sound comes on. Anyway, I sent it in for repair and they swapped a new fan in and it's been running just fine for almost 1 week.
