Is there a way to turn DOWN the fans? I think it is the fans spinning, they are running at about 2K each.
The MBA has one fan and by default the minimum speed is set to 2500rpm. You can rev it up using SMC Fan Control, but I have yet to find software to turn fans down. It would be nice since the MBA takes a longer than usual time to spin fans down from a high rev even when the temp gets stable at 40C.
