The NexXxoS Full Copper series

Alphacool says it has dominated the market with the NexXxoS Full Copper radiator series for more than a decade. In its words: "Our extensive portfolio of radiator variants is unique in the world." Just like its manufacturing process, it adds, "which allows us to produce" every water-carrying part and the fins out of copper. As a result, Alphacool claims, the series offers the highest thermal conductivity of any radiator on the market. Thanks to their exceptional performance, it says, the radiators can easily dissipate even extremely high waste heat and have become essential in many areas of the cooling industry.

What the loop needs

A loop runs in through one IN/OUT port and out through another, so the radiator takes two G1/4 fittings, with a thread length of 5 mm at most. It holds one 140 mm fan on one side or two with both sides fitted, on M3 threads. All screws for mounting in the case and for mounting the fans are included with the radiator: 4x M3x5 for the case and 4x M3x30 for the fans. Additional screws are not usually required.
