I'm playing Neverwinter Nights (the first one) on my 2.0 GHz Aluminum Unibody MacBook. I haven't done any upgrades on my RAM and HDD but I do believe that it's more than enough to run the game without heating up. Gameplay doesn't lag but, God, after a few minutes of playing the fans kick like I'm running Crysis or something. I'm wondering if there's an option to enable CPU throttling in NWN. A certain update in StarCraft made it possible to do that so my MB doesn't get too hyped up when I play StarCraft. Any suggestions? I tried setting the resolution and graphics to the lowest possible options but it still heats up.
