While the 360 can run hot if not properly ventalated, this plug in fan doesn't stop the 360 issues out there. You 360 and power supply needs to be in a position where air can flow thru easily. Try and avoid having your 360 and power supply on the carpet or areas where there is little airflow. That being said, I do believe this cooler helps to cool the 360 slightly. The intercooler has 3 fans running, and it plugs into the back of the 360. Then you plug the cord into it. I have a problem with the fact the intercooler uses the voltage from the 360, instead of its own powersource. The fact its taking amps away from the board is theorectically not a good thing. You don't need a cooler, UNLESS you can't put your 360 in an open area. If you have to get one of these, may i suggest the 360 Stand instead. Some of them have batteries or they plug into the wall. That way no power is lost from the 360. These things don't extend the life of your 360, and they will not stop the 360 crashes that have plagued the system since birth. I've have talked with techs at two major repair centers, and they all say this will not solve the 360 crash issues. If you have to have one, then get the stand that uses its own powersource. You have been warned!
