Integrated Radiator. Joins Heat Source Block and Ambient Heat Exchanger to maximize heat transfer efficiently without evaporation. Simplifies installation. Heat is removed instantly thanks to the Liquid Loop made out of pure copper tubes. Copper Tubing minimizes liquid evaporation. Brazing Heat Source Block Silver, which has higher heat conductivity than copper is used to provide best heat transfer possible. Advanced Brazing Technology provides the industrial-grade water-tight seal, no leaking and more reliable. Versatility: Either 80mm or 90mm fan can be used on Ambient Heat Exchanger. Supports all Thermaltake's liquid cooling accessory such as pump, radiator, VGA water block…etc. Y-tube accelerates the transferring frequency of liquid flow. Fits on all AMD and Intel CPU's
