With their 360, try this. Reminder this ONLY for people who are not covered by MS warranty. Remove the casing. Stand the console so it is vertical. Take a small tower fan(about the same height of the console. Put the fan so it is where the bottom of the console is about an inch away. This will work. I played Mid Night Club LA for 4 hours and not one freeze. I also played Fallout 3 for 3 hours and not one freeze. Before I did this, it so hot it would burn you. Now the metal bottom part is merely warm to the touch. A little extreme perhaps, but it is better than the alternative.
