    I discovered in Boot Camp mode that my unibody MBP runs a good 8˚C cooler when I have the lid open while playing intensive 3D games. In the nVidia control panel I can disable the built-in display and use my external monitor only. Is there a utility or command that would let me do this in OS X, or at least a way to disable the second screen's extra desktop space?

    Any particular reason you'd want to disable the second screen, instead of just letting it sit on the desktop? You can turn down the resolution if you just want to scrounge up more GPU power.

    Btw, thank you for validating my point the MBP's cooling system is severly compromised in clamshell mode. It's kind of obvious from looking at the hinge, but some people here don't realize that.

    Close the lid when it's asleep, plug in the display, then plug in the external mouse/keyboard. When the display awakens, open up the lid of the MacBook Pro. the display will remain off. Voila!!

    Would anybody know if the MB has the same temperature issue as the MBP clamshell mode?
