Black dual-fan copper radiator, 280 by 124 by 46mm, G1/4 ports

Alphacool

Alphacool NexXxos XT45 Full Copper Radiator 240 45mm Black G1/4 14164

SKU CH-Q82D-WPNA9

A 240 mm dual-fan radiator with full copper chambers, fins and channels for custom water-cooling loops

  • TypeRadiator

Size 240mm

  • Full-copper chambers and fins boost thermal transfer
  • 45 mm core depth increases coolant volume and surface area
  • Six G1/4 ports allow flexible loop routing
  • Dual 120 mm fan layout fits standard 240 mm mounts
  • Black steel side panels protect copper internals

240 mm Full-Copper Radiator for Custom Loops

This radiator uses copper chambers, fins and channels instead of the usual brass or aluminium mix. Two 120 mm fan positions provide a 240 mm cooling surface for custom liquid-cooling builds. The black finish suits stealth-themed systems.

Six G1/4 Ports and Separated Chambers

Six G1/4 threads allow flexible inlet and outlet routing in any orientation. Internally separated chambers direct coolant along a defined path, reducing flow dead zones. Steel side panels add rigidity while brass threads resist stripping during repeated fitting changes.

Fits Standard 120 mm Dual-Fan Mounts

The 280 x 124 x 46 mm footprint matches common 240 mm radiator mounting holes, so installation follows normal case patterns. Weight of 1199 g requires secure fastening to avoid stress on tubing joints. No proprietary brackets or adapters are included.

Questions about this item

Will the copper fins and chambers need any special cleaning or replacement over time?

The radiator uses full copper construction for chambers, fins and channels, so no internal parts require scheduled replacement; periodic flushing with distilled water keeps the loop clean.

At what coolant temperature does the 45 mm thick core stop dissipating additional heat under continuous load?

Thermal limits depend on fan speed, airflow and total loop heat load rather than a fixed coolant temperature, so the radiator itself has no published saturation point.

How much pump head pressure is needed to push fluid through the six G1/4 ports during all‑day operation?

The internal copper channel layout creates low restriction, so most standard D5 or DDC pumps provide sufficient flow without excessive noise or heat from the pump itself.
