Hello Everyone - I've had my MBA for close to 6 weeks, it is a week 10 built Air. Everything is perfectly fine except for the little ticking noise that is coming from the fan @ 2500 RPM. It always occurs when I first turn the Air on. However, once the fans kick in @ 6200 RPM and shortly go back to 2500 RPM the noise is gone for approx 5-10 min. THEN, the tick goes back to it's loud state. It sounds like someone is sticking a playing card in the fan very gently. I've taken it to the Apple Genius bar and he was a complete waste of time. He worked the CPU by typing YES in the terminal and saying everything is fine and he can't replicate the noise.. My question is what can I do to resolve this problem? I don't want a refurb MBA as they MIGHT give me, all I want is this problem fixed.. I am going to try another Genius Bar in a different city. Any one else with this problem? Thanks in advance.
