Is this normal..........................?

This is how my 40GB PS3's fan sounds like after 1 minute of turning it on:

Note: This video was recorded using a mobile phone just next to my PS3's rear vents.

sounds fine.

Well its not a normal fan sound, but until it gets loud, dont worry about it. Its probly just a dirty fan motor, or imbalanced fan blades. Call Sony if it bothers you, dont wait until the warranty is done.budboarder

Is that fan sound a big problem or just an easy fix?
