Cooler Stand Does The Cooler Stand Really Work?

Does the cooler stand really work? - cooler stand

Like many others I'm stupid and freeze ringing in my Wii. It all started when I played Harry Potter. Never happened, but I must admit that what he had seen running over a long period of time. I am convinced that this is due to overheating. A reasonable solution seems to be cooling my refrigerator at the foot. I've heard that a heat exchanger 360 is worse because of the heat exchanger generates more heat, which is scattered. If the foot cooler for the Wii comes with the same problem or is it really worth to buy?
