The Thermaltake TMG AT2 is a cooler for ATI's Radeon X1800, X1900 and X1950 Series. It uses a combination of copper and aluminum to optimize the cooling. We compared the cooler to the Arctic Cooling Accelero X2 and the Zalman FC-ZV9 Fatal1ty. The temperature results were among the best of the tested coolers. Not only performance is great, but the installation is also very easy to perform, in just a couple of minutes.
