My xbox 360 just red ringed. I mean, I have heard it happening to other people, but never expected it to happen to me. This happened to me before, when I was using this cooler. So, from past experience, just unplugged the power cord, and plugged it back in. Guess what? It turned on. I didn't test it, removing the game, then turning if off. If this happens again, I am going to Best Buy for my warranty.
