I'm used to the loud fan noise and heat after a year, but now my MBP seems to be going to sleep due to heat. I've seen this happen three times so far in the last week, in Legend of Grimrock and Skyrim (both on Windows of course). I'm not certain it's a heat issue but I can't think of anything else that would cause the computer to randomly go to sleep during a video game. Anyone had a similar experience? I'm probably going to take it to an Apple store before the warranty goes out. Thanks.
