The Alphacool ES water cooler with backplate was specifically designed for the Alphacool Enterprise Series. The copper cooler meets the highest standards, making it reliable for use in servers and workstations. This cooler is not 1U compatible! More performance! Alphacool positions the cooler optimally on the components to be cooled. By minimizing the thickness of the copper block and optimizing the water flow within the cooler, all critical parts such as the GPU, voltage regulators, and VRAMs can be cooled much more efficiently and effectively. This results in a significant improvement in cooling performance. Chrome-plated copper The cooler is made entirely of chrome-plated copper. A chrome plating is much harder than a nickel plating and therefore less sensitive to acids, scratches and damage. It completely eliminates the risk of chipping nickel plating. Additionally, chrome plating looks much more homogeneous and provides a shine that cannot be achieved by nickel plating. Copper or aluminum? Alphacool uses only copper for all water-bearing parts. Copper has almost twice the thermal conductivity of aluminum and is therefore clearly the better choice of material for water cooling. The chrome-plated copper base is highly resistant to acid, which means that chipping of the chrome plating can be ruled out.
