    I just tested a few games running on my MBP 15' 2010 Base:
    I have OCed the nVidia 330M from 500/790/1100 to 575/790/1265

    Everything tested on Windows 7 64bit with MBP placed on a book in my bed :D

    Shift 2: (One race)

    OCed - Starting temp: 62° goes upto 87° then the fans kick in to keep it on average 77°

    Not OCed - surprisingly exactly the same temperatures, but the 87° held there for a shorter period of time, about 20 seconds less before the fan kicked in

    Crysis 2: (Beginning of a mission)

    OCed - Starting temp: 56° goes upto 90° then the fans keep it on 79° on average

    Not OCed - The top temperature is 90° as well, but holds there about ten seconds less then when oced before the fans kick in

    Modern Warfare 2: (Longer session - about two hours playing online)

    OCed - Before the fans kick in, it goes upto 86°, the average for a whole match is 77° in lobby goes to 66° and this repeats every match

    The temperature of the room is 75-76°F

    Logs done with nVidia System Monitor, Driver 275.33 original, OCed with nVidia Performance.

    My question is, if this is ok ?:confused: the 90° by Crysis 2 scared me a bit.

    What do you think ?

    it's fine. You only have to worry when your computer shuts off. And that happens at around 100C. The highest mine has gotten was 94C

    Yeah, 90° would be as high as I go, but even that shouldn't do much harm. The only thing I would worry about is the components around it (capacitors and such) getting too hot, but I don't know much about that, so I don't know if it is something to be worried about.

    I know Intel CPUs you can't really fry because they lower their frequency based on the temperature, but I don't know if nVidia GPUs do the same.

    Found another thread here. GGJstudios made a good point, your MacBook Pro should shut itself off if it gets too hot.

    Thanks guys, maybe the 90° was achieved because the MBP was not sitting above the ground on its stands, I ll test it further.

    Although its weird, that with the base clock the temp went upto 90°...:rolleyes:
