Upgraded my 2011 MBP to 10.8.2 last night and as soon as it rebooted my fans have been going nuts constantly. I've tried rebooting, and running with no apps so just the plain desktop but my fans are running at what seems full speed all the time now. Have tried on integrated and discrete graphics but same problem. Anyone else having this problems? Guess I'm going to have to roll back to 10.8.1 now. Geez, this as my iPhone getting stuck in the Recovery Mode cycle for 6 reboots before taking iOS6, this update cycle isn't my good time.
