For over a decade, Alphacool has dominated the market with the NexXxoS Full Copper radiator series. The extensive portfolio of radiator variants is unique worldwide. Just like our manufacturing process, which allows us to produce all water-carrying parts and cooling fins from pure copper. This enables the NexXxoS series to achieve the highest thermal conductivity of any radiator on the market. With their unparalleled performance, these radiators can effortlessly dissipate extremely high waste heat and have become indispensable in many areas of the cooling industry. The next evolutionary step: NexXxoS HPE Full Copper Radiator! The NexXxoS Full Copper HPE radiator uses the same materials as the previous NexXxoS models but takes a technical step further. The compact internal structure has increased the number of water channels and copper fins. This results in a larger water volume in direct contact with the cooling fins and improved heat transfer.
