Product information

Description

The Alphacool NexXxoS HPE Full Copper radiator continues Alphacool's long-standing NexXxoS tradition of using copper for all water-carrying parts and cooling fins to maximise thermal conductivity. This HPE (High Performance Edition) model increases the number of water channels and fin rows through a condensed internal structure, improving direct contact between coolant and fins and raising overall heat transfer. Compared with a conventional NexXxoS radiator, test results show a performance improvement of up to 4.5 K under the stated test conditions and up to 6 K at higher ambient temperatures and fan speeds.

Advantages

The NexXxoS HPE radiator is manufactured from copper for both the water channels and fins, giving it very high thermal conductivity. The denser internal layout increases coolant contact with fins and more efficiently uses the cooling surface via additional and shorter fin rows. Integrated G1/4" connections, a fill/drain port and recessed patented screw plugs simplify installation and mounting, while protective plates under mounting holes prevent damage to fins and water channels.

Suitable for

  • Custom liquid-cooled PC systems requiring high thermal conductivity
  • High-heat setups such as overclocked CPUs and powerful GPUs
  • Compact radiators installations where efficient heat dissipation in limited space is needed

Key specifications

  • Brand: Alphacool
  • Model / MPN: 14378
  • Materials: brass/copper/steel construction with copper water-carrying parts and fins (NexXxoS HPE full copper design)
  • Finish: black
  • Dimensions (L×W×H): 314.5 mm × 144 mm × 30 mm
  • Threaded connections: two G1/4" IN/OUT ports in pre-chamber area; separate fill/drain port

How to use

Install the radiator in your PC case using the included mounting screws and attach fans as required. Use the G1/4" threaded ports to connect the radiator into your water-cooling loop; the opposite-side fill/drain port can be used when filling or draining the circuit. Ensure fittings are tightened to avoid leaks and that the radiator is mounted with its protective plates aligned under the mounting screws to prevent over-tightening damage.

Usage recommendations

For best performance, use appropriate high-flow fittings and compatible fans. Verify compatibility with your case and component layout before installation. When operating at high ambient temperatures or elevated fan speeds, the HPE radiator delivers a progressively larger performance advantage over conventional NexXxoS radiators.
