Yes they do over heat, and when it doesn't the system shuts down for about 30 minutes (or until it cools back down). It normaly over heats if u block the back of the system where the cords are. But mines doesn't even use my fan cooling system that much because I Install every game I have onto my hard drive because the system typically heats up because of disk readings.
I do agree with you all on this. People do complain a lot about how slow the shipments are. But they apparently still do get there games, they don't have patients at all. Any why would u complain in the Answers tab when u can file a shipping report about it? the longest it took me to get a game was 2 weeks I filed a report on the 7th business day like it said and I got it a day or 2 later.
