Mine has overheating problems because of where it sits in my house (and it's not just the XBox... somethings the PS2 and Gamecube have the same problem). I know, I know, I need to get them relocated. However, that's not an option at the present time.
A coworker of mine indicated that the following device had solved the overheating problem with a friend of his. Anyone have any experience?
