I had a macbook air 13', 128G (mid 2011). I recently installed two updates (EFI and Thunderbolt). After that, every time I woke up the computer, CPU temperature starts to rise with even 0% CPU usage. It gets really hot (CPU temperature of 80 celcius) after 10 minutes and the fan drives me crazy. I have never had this problem before the updates. The solution is to restart the computer. Has anyone experienced the same problem?
