NexXxoS Full Copper

Alphacool says it has dominated the market with the NexXxoS Full Copper radiator series for more than a decade, and calls its extensive portfolio of radiator variants unique in the world. It says the same of what it describes as "our manufacturing process, which allows us to produce all water-carrying parts and the cooling fins out of pure copper". Just like every NexXxoS, the radiator offers, as a result, what Alphacool claims is the highest thermal conductivity of any radiator on the market. Thanks to what Alphacool calls exceptional performance, the radiators can easily dissipate even extremely high waste heat. By its account they have become essential in many areas of the cooling industry.

What the loop needs

Under "Connection options & mounting", Alphacool's text gives the radiator two IN or OUT connections with G1/4 threads in the pre-chamber area, while its table lists 4x G1/4 IN/OUT. A loop uses two of them, so the radiator takes two fittings. On the opposite side is a fill or drain port, which can be used for filling and draining the water circuit. The table names it the fill and drain port, and thread length in every port is 5 mm at most.

The radiator takes 140 mm fans on M3 threads, and the possible fan assignment is three on one side or six on both sides. All screws for mounting in the case and for mounting the fans are included with the radiator: twelve M3x5 case mounting screws and twelve M3x30 fan screws. Alphacool says additional screws are not usually required.
