I've installed windows xp on my mbp to play some games and the only thing that really worries me is the temperature. When I play civilization IV the temperature gets up to 73C/78C degrees with my fan spinning at 4800rpm. Is the mbp made to sustain temperatures like this for a long period of time? I know the mbp is not a laptop designed for games but can it take the stress from games? Only thing I hate to accept is the fact that the more the heat, the less the life expectancy.
