Throw a cheap laptop cooler under it, if you can spare a USB port hookup.
Careful with doing that, I have had a cheap cooler kill my usb port on my laptop and it was the only one that it had so I was SOL. I was told once it was better to get a powered usb hub and plug the cooler in to that, that way it won't screw with your mb if it's not a proper usb connection.
