If you are pushing the envelope with performance computing such as gaming or rendering photos or animation, your machine can run hot. Way too hot. Don't trust air-cooling to protect you. Put your system on ice - with COOL by Corsair, 120mm advanced PC water-cooling system. This compact, powerful unit fits largely within your case for a sleeker look and more integrated performance. Unlike any other cooling unit, COOL is based entirely on 3/8" tubing with no converters to restrict flow. The tubing comes factory-clamped to the cooling block and stress tested to ensure leak-free performance.
