I have a 2010 MacBook Pro MC371 (Core i5, GeForce 320M, 4Gb RAM).
When I launch a game either new one (i.e. Starcraft 2) or rather old (Unreal Tournament 2004, bootcamped) my MacBook gets rather warm, even hot in the top left corner, around the place where magsafe charger is plugged in. The temperature is more than 40C. The fact that confuses me is that this warming occures even when I play old games.
Is that OK?
