The Zalman Reserator 1 is designed with an optimal heat dissipation area based on ZalmanTech's HCET (High Capacity Extrusion Technique) and high efficiency cooling technology. As a result, this product achieves excellent cooling performance even with natural convection, making it the world's first fanless, noiseless water-cooling system. The reservoir, radiator, and the water pump are conveniently integrated into one assembly, and the heatsink is anodized to prevent corrosion and rust. In addition, the kit includes the high-performance ZM-WB2 Gold waterblock which is not susceptible to galvanic corrosion.
