After setting up the cooler in my room with the Xbox 360, I began to do some testing. I sat down and played an hour straight of Project Gotham Racing 3 and then felt the 360 power supply to determine how effective the cooler was. Surprisingly, it felt as if the unit had not even been on for days. Overall, I'd say the project was highly successful. I now have zero problems with the 360 freezing up. In the future I plan on fixing the design to make it more appealing to the eye and to get the temperature even lower. Right now, I'd say this is the best solution to keeping your 360 from freezing up and/or starting a fire.
