When I first heard about a fanless power supply, I had my doubts. When you get down to it, the hot air has to go somewhere and without any circulation how would it do this? Thermaltake got around this issue by thinking outside the box or rather putting the convection fins outside the box. The most notable feature you see right off is that on opposing sides of the unit are areas where copper convection fins extend out of the power supply housing (25mm on one side and 63mm on the other.)
