Xigmtek's cooler series has a lot of potential. They have some great numbers straight out of the box with near silent fans. The Xigmatek XP-S964 has a great new design that is sure to get the curiosity out of some builders. I still have a hard time believing that skewing the shape of the block will help the heat transfer. Essentially you are taking cooling ability from one corner and pushing it off the opposite. I really believe that if this cooler had a standard square block, the numbers may have improved.
