I have the base 13" '11 as most of you know. Whenever I run a graphic-intensive program like Google Earth, either pan through cities or enter street view to the deliver the quasi-experience of driving, my MBP heats up to like 80s and it seems the sky is limit. I could push it over 90 C without much hassel. These problems have been well documented here. But, I've done this test on various computers at the Apple Stores. Both 13" models, and 15-inch models. And I have never been able to push them above 90 on Google Earth, perhaps I need to try harder. The 13-inch models hit the mid-80s easily, but after a while it seems like they would level off around 80 or below. Should I try to exchange mine?
