Also, a little side note here..., Windows doesn’t have as good power management capabilities as Mac OS X, so..., you’re going to get worse conditions with Windows running the show with heat and battery life. The Mac OS X will give you better performance and results on the MacBook Pro.
It doesn't seem to be a problem with the Mac OS X and it's power management systems.
CPU will force shutdown when it hits about 110'C.
Average temperatures are anything from 48'C - 90'C. The fans in the new Unibody MacBook Pro's have more blades so create greater air flow - at 6000RPM with full CPU load, you probably won't peak over 80'C.
I did a Handbrake encode last night on the new MBP work gave me. It worked at 100% CPU for almost three hours. Temperature peaked at about 80˚C, fans were no more than 3000rpm. Under normal use, it's at about 40-45˚C
There's nothing special about these comments... just a couple of users talking, that's all...
I think one of the nice things about the MacBook Pro is that it can suck the heat out of the CPU so well, so as to not cause problems for it. At least it seems that way for me. If it's getting hot outside, it's working ... :-)
