Alphacool NexXxoS XT45 X-Flow 280mm Radiator

The Alphacool NexXxoS XT45 X-Flow is a full copper liquid cooling radiator measuring 280 mm in length with dual 140 mm fan slots. Its 45 mm thickness houses copper chambers, fins and channels designed for high flow rates. It suits enthusiasts building custom water cooling loops who want maximum thermal capacity from a single radiator.

Suits custom loops needing high flow

This radiator fits builds that can accommodate a 280 mm by 45 mm form factor and dual 140 mm fans. Builders with restricted mounting space or single-fan layouts will need a different radiator size. It includes two screw plugs and mounting hardware for standard G1/4 connections.

45 mm thick full copper core with X-Flow design

The defining specification is the 45 mm thick full copper core using an X-Flow internal structure built for high flow rates. This construction sets its thermal performance ceiling and determines whether it fits the available clearance in your chassis.

Questions sur cet article

How do I install the 280 mm radiator and which step often causes leaks?

Mount the radiator using the included hardware so the two G1/4 ports face the tubing run; the step most builders miss is tightening the two supplied screw plugs into the unused ports before pressure testing.

What maintenance will the full-copper 45 mm thick core need later?

Flush the loop and refresh coolant once a year; the all-copper construction resists corrosion, but the two G1/4 screw plugs and their O-rings should be inspected and re-seated during each service.

What limit appears first when the 140 mm fans run at sustained load?

The 45 mm fin density restricts airflow, so static pressure from the 140 mm fans becomes the bottleneck before the copper core reaches thermal saturation.
