For more than a decade, Alphacool has dominated the market with its Full Copper radiator series. Our extensive portfolio of radiator variants is unique worldwide, just like our manufacturing process, which enables us to craft all water-bearing parts and cooling fins from pure copper. Thanks to their exceptional performance, these radiators can effortlessly dissipate even extremely high waste heat, making them indispensable in many sectors of the cooling industry. The next step in evolution: HPE Full Copper Radiator! The Full Copper HPE Radiator uses the same materials as the previous NexXxoS models but takes a technical step forward. With a denser internal structure, the number of water channels and copper fins has been increased. This design ensures a larger water volume is in direct contact with the cooling fins, significantly enhancing heat transfer. The increased number of fin rows and their shortening also results in a much more efficient utilization of the cooling surface. Connection options & mounting The HPE radiator features two IN or OUT connections with G1/4" threads in the pre-chamber area. On the opposite side, there is a fill or drain port for filling and draining the water circuit. The radiator comes with all necessary screws for case and fan installation. Additional screws are typically not required.
