What are the maximum temperatures for my MacBook Pro?
I have a pre-2009 Unibody MacBook Pro. My Mac went over 105°C and still worked. 

Typing was about 200% slower—around one word per minute—but I was playing a Flash-based game and have noticed the game raises the temperature to around 90°C in about 5 minutes of playing. 

So I think the maximum temperature is around 110–120. Then it shuts off automatically.
