I bought a new MBA 11" i7, it's about two weeks old.
I've noticed that as soon as the fans come on, they Never turn off. If I watch a video, or do any slightly heavy lifting, the CPU hits 70C, the fans come on at +6000rpm and never turn off.
Even if the CPU load is less than 1% for an hour or more, the fans stay on full-blast and the CPU temp stays at ~67C and the case at ~35C. The room is normal temperature, it's sitting on a desk.
The only way I've found of making the fans turn off is to make the Mac sleep for a while.
Is this a known issue? Are other people having similar problems? What can I do to resolve this?
