EK-CoolStream SE 480 (Slim Quad) The smallest 120mm series of radiators available, with a width and height the same size as a standard 120mm fan this is the perfect radiator for small-form-factor (SFF) builds Recommended radiator guidelines: 120mm of surface area per component + an additional 120mm on top. For a system with one CPU and two GPUs we recommend 480mm of surface area, this can be accomplished with any combination of smaller radiators Supported Fans: 120mm (x4) Dimensions: 520 x 120 x 26mm Brass Chambers with Copper Fins
