Recently, I did some home repairs to my Xbox 360 including disassembling the unit, removing and replacing the thermal compound, (though, I didn’t replace the xclamps) and reassembling it. This made my 360 work for awhile, but then it quit, so I tried the penny trick (replacing the 4 thermal pads under the motherboard with 2 pennies wrapped in electrical tape), and it worked! But whenever I put in a game to play, it runs for about 3 minutes and then shuts off with blinking red lights in the 1st and 3rd quadrant of the power lights (the sign of a general overheating problem). It will run for hours just sitting at the dashboard, but as soon as I start to try and play a game, including games I’ve downloaded like “Limbo,” it says it’s overheating after only a few minutes of play. It will play movies I put on my flash drive with no issues. I’ve checked the power brick, and that’s not overheating either. I also have an intercooler attached to the 360, and that isn’t helping the matter whatsoever. Are these all related to one specific part of the 360 that can be cooled? Is it possible it’s the disc drive overheating? Is there something I’m missing? I’ve had my 360 for about 7 or 8 years with no complications previous to this, so if there are no other suggestions, I suppose I am due for a replacement, but if I can fix this one, that would be ideal.
TL;DR: 360 still overheating after suggested repairs, don’t want to buy a new one. Ideas for alternative repairs?
