Hi there, Sometimes I have a problem with MBA 2011: it produces a lot of heat (CPU temp around 65-70C) but activity monitor shows 90-95% idle (same with top command). Checked and cleaned fan - it's works fine. Battery drains faster too when it happen. There is no disk or network activity. Tried to close almost every app - didn't helped but restart usually helps. Does anybody had same problem? Heat issue and fan noise are very annoying.
