Buzzing Noise on New Macbook Air Rev B

[terryrocks]

Hi everyone,
I purchased a Macbook Air from Amazon. The display is excellent but i've been having this constant buzzing noise going. It's very irritating and I'm not sure what is causing it. I definitely didnt hear this noise in my rev A Macbook Air or in Macbook air sin the Apple store. Does anyone know what could be causing the problem? Do you think I should make an exchange at Amazon?

Any advice is appreciated

Thanks!

What's the RPM when it's buzzing? If it's buzzing at 6500 RPM, then it is normal. If it buzzes at 2500 RPM, it means the fan bearing is loose. They will repair it for you for free if its under warranty.

Hi ooo,
Thanks so much for responding.
Do you know what software I can use to check what RPM is on when this is happening?

Thanks!

The iStats menu is quite nice as it lets you get a view of what's going on with your machine: both fan RPM and temperature as well as CPU, etc. All without having to pop to the dashboard.
