Is this normal? I've never noticed before but doing anything CPU intensive results in an almost immediate CPU throttle. This is with a 2011 MBP 2.2Ghz quad core i7 running 10.8 with all updates. My temperatures appear normal and my fans are not running loudly so I don't understand why this would be happening My handbrake encode is estimating 3.5 hours for a single 1080P movie. This is another test using "yes" commands in terminal to max out the CPU. There are 6 instances running but the temperature only rises slightly.
