Limit CPU usage for an application/process
Authored by: BryanD on Feb 04, '11 03:01:37AM

'Though Fan Control can help keep a MacBook Pro cooler, ultimately things that hammer both CPUs can get things so hot that even the fans won't keep the temperature down — and high heat will shorten the lifetime.

There's another trick that I use — just pop out the battery and the CPUs will be limited to 1 GHz (at least this is the case with my MBP Dual 2.33 GHz machine). While you obviously need to keep the unit plugged in (and mine's normally also on a UPS circuit when I do this), it's about impossible to get the unit too hot when it's limited to 1 GHz. Great for those multi-hour processing jobs.
