i installed windows xp on my macbook, and i started to play this game called KnightOnline. the macbook is good enough to meet all the requirements for the game:

Hardware/Software Minimum Requirement Recommended
Operating System Windows 98/2000/XP/ME Windows 98/2000/XP/ME
CPU Celeron 300 or above Pentium II 400 or above
Memory 128 MB or above 256 MB or above
Hard Disk Space 400MB or above 600MB or above
Video Card 16MB or above 3D Display Cards with DirectX support 32MB or above 3D Display Cards with DirectX support
Additional Software DirectX 8.1 or Above

but my problem is when i log in to the game, i can start to hear the fans going crazy, and right above the "vent" under the screen, it gets pretty hot.

i also run a "SpeedFan" to monitor the temperature of the macbook and it doesn't get any hotter when i run the game.... any ideas on how to fix this?
