Since new this MacAir has had a white noise like a tv not tuned in even when sound is off. Gets worse as it gets warmer. Seems to be getting worse then ever.(summer). Usually connected to a Thunderbolt Display and makes noise only when display is attached. Disconnect the display and the noise goes quite after a few minutes till display is again attached.

Mountain Lion OS X 10.8.2 (12C60)

I think it is the Cooling Fans making the noise and the Thunderbolt connector gets hot after a few minutes.
