So I got my 2.53 gHz (late 2008) MacBook Pro last week Monday and I love it, but I've been having some heat problems. It's mainly with the GPU, everything else seems to maintain decent temperatures. So this only really happens when running XP and playing Crysis. Yes, I know this why it runs hot. The game suggested running everything on high, but I turned the water, particle, volumetric, and shadow effects down to medium. It runs pretty well, around 15-35 FPS with the median around 25-30ish. Also, I'm running this through an external monitor (an older 24inch cinema display), not sure if that makes a difference (LCD was running too). I noticed a problem after playing for about 10-15 minutes, the LCD completely shut off and I was forced to cycle the power. This happened again so I felt the bottom of the computer. Burning hot, I couldn't keep my hand on it for more than 2 sec. I have one of those notebook fan bases so I put that under it and propped up the back a little extra. I left the computer to cool off for a bit and didn't touch it until (presumably) it was at room temperature. When I turned it back on it read 72c after 10 minutes of idle. After running Crysis for 5 minutes it read 85 with a high of 92. After playing for another 10 minutes it keep pretty steady around the low to mid 80s. Is this too hot for my GPU? I don't want to fry anything or work it too hard. Everything else seems to be fine, and it only really gets hot while running XP. While running Leopard it runs around 60c. I don't know, some advice would be appreciated.
