Imac Buzzing sound (any solution?)

[Crevice]

My brand new 24 inch iMac makes an annoying buzzing sound that is driving me nuts. When I tilt the screen up it goes away, and when I tilt it back down it comes back. I know people have had this issue, but has anyone actually had this fixed? I am guessing it is a fan inside making this sound. Just curious if anyone has any ideas what to do, and if they have had this problem.

Take it in to your nearest Apple Store or send it in to Apple for servicing.

Any luck with this Crevice, cos I think mine may be doing the same thing?

Have you taken it into a store?
