Some guy in Chicago is suing Microsoft because of overheating problems. Link here.
Whatever. Apparently this is all because the power supply gets hot.
1. Play with your Xbox outside in the snow. However, this works if you live in a cold climate near the arctic circle (and hence dark enough during the day to see your monitor). So scratch that idea unless you live north or south of a 60th parallel.
2. Simpler: Just raise the power supply off of the ground or whatever flat surface it’s lying on. The simple use of string works just fine.You don’t need to open up anything, just get the power supply in a position where the heat can dissipate in all directions.
