280 mm Full-Copper Radiator

The Alphacool NexXxoS XT45 is a 280 mm water-cooling radiator built entirely from copper, including its chambers, fins and channels. It targets custom-loop builders who want maximum thermal conductivity from a single heat exchanger. The unit ships with five sealing plugs and two sets of M3 mounting screws.

Thermals Noise Power

Full-copper construction improves heat transfer compared with mixed-material designs, giving the coolant a directed path through separated chambers. Two 140 mm fan slots allow builders to choose airflow and static-pressure profiles that match their noise targets. No pump, fans or power-draw figures are supplied with the radiator itself.

Build Integration

The radiator occupies a 280 mm mounting space and accepts standard 140 mm fans using the included 30 mm or 35 mm M3 screws. It frees the builder from sourcing separate plugs and hardware for a clean installation. Loop designers must supply their own pump, reservoir, tubing and coolant to complete the system.

Questions sur cet article

How do I install the 280 mm radiator and which screws should I use for 140 mm fans?

Mount the radiator using the eight M3×30 mm screws for direct fan attachment or the eight M3×35 mm screws when placing a 140 mm fan with a rubber gasket between fan and radiator; the longer set prevents the screw bottoming out before the fan is secure.

What maintenance will the full-copper radiator need over time?

Flush the loop once a year with distilled water and a mild biocide to stop oxidation inside the copper chambers and channels; inspect the five brass plugs for weeping and re-tighten them if any coolant residue appears.

What thermal limit appears first when the 45 mm thick core runs continuously at high load?

The 45 mm core’s fin density saturates airflow from the two 140 mm fans, so coolant temperature stops dropping once fan speed reaches the point where pressure drop equals the fans’ maximum static pressure.
