Constant, buzzing noice from mac, but fans' RPM normal?

[Mgreen]

Hey guys

My MBP Retina just recently developed a constant humming/buzzing noice just loud enough to drive me crazy in a quiet room. RPM of the fans are 2000, but it still sounds like it's coming from the left fan area (Perhaps some dirt or a small tear in one of the fans?)

Anyone got any suggestions to the diagnosis and solution of the problem ?

Thanks!

I would take it to Apple and have them open it up and clean it out. They will also be able to run the computer with the fans and see if the noise persists. They of course do that kind of thing free of charge, just make an appointment first and then take it in.
