Product details

The NexXxoS V.2 Radiator is the evolution of the already proven NexXxoS V.1 series and rightfully takes its place among Alphacool's high-end full copper radiators. The fresh design in modern, elegant white and the numerous technical details make the NexXxoS V.2 Radiator the perfect partner for your own water cooling system. Uncompromising in material choice, Alphacool exclusively uses copper for all water-carrying parts in the radiator. The chambers, cooling fins, and cooling channels are made of pure copper. Only the connection threads made of brass and the outer casing of the radiator made of steel sheet consist of different materials. To maximize the radiator's performance, Alphacool uses pure copper for the cooling fins, cooling channels, and chambers due to its high thermal conductivity of 400 W/mK (for comparison: aluminum 236 W/mK). The radiator features a special fin density.
