The world-famous manufacturer Alphacool is currently the only manufacturer in the world who uses pure copper for all water-bearing parts. The antechambers, water channels and the fins are all made of pure copper. As a result, Alphacool radiators offer the highest thermal conductivity, which means that the performance limit is significantly higher than that of aluminum radiators. In short, the cooling capacity is simply higher if you want to dissipate a lot of heat. Copper has been the best choice of materials in the water cooling sector for years.
