Strange computer behavior - and.. boring game?

On my old iMac 2007 - core duo 2,4 ghz, this game works fine. But on my newer MBA 1,7 ghz intel core 7, the fan is constantly running. Weird… Also, after all the hype surrounding the game, I decided to give it a try to see by myself. I have to say I find this game pretty boring so far.
