Product information

Description

The Alphacool NexXxoS XT45 Black Copper Steel 422x441x48mm radiator block is a liquid-cooling radiator designed for high-performance PC cooling systems. Constructed with copper and steel and finished in black, it combines a large cooling surface with a robust build to support demanding thermal loads. With dimensions of 422 mm × 441 mm × 48 mm and compatibility with 140 mm fan mounts, the unit is intended for integration into custom water-cooling loops where efficient heat rejection and material longevity are required.

Advantages

The copper and steel construction provides effective heat transfer and structural durability while the black finish offers a neutral appearance for varied system builds. The radiator's large physical size increases available cooling surface area, and its design supports standard 140 mm fan configurations for flexible airflow management. A relatively high mass supports thermal inertia useful in sustained loads, and threaded connections allow standard G1/4" fittings for loop integration.

Suitable for

  • Custom PC water-cooling loops for CPUs and GPUs
  • High-performance workstation and gaming builds requiring enhanced heat dissipation
  • Systems using 140 mm fan mounts for airflow-based cooling

Key specifications

  • Material: copper (heat-exchange elements) and steel (structural components)
  • External finish: black
  • Dimensions (W×D×H): 422 × 441 × 48 mm
  • Compatible fan diameter: 140 mm
  • Weight: 4.225 kg
  • Cooling channel and fin construction optimized for airflow with serrated fin edges
  • Threaded ports compatible with G1/4" fittings (IN/OUT and additional service port)

How to use

Install the radiator into the PC chassis or external mounting location with appropriate fan and bracket configuration for 140 mm fans. Connect the radiator to the water-cooling loop using G1/4"-compatible fittings and tubing, ensuring IN and OUT lines follow the recommended flow path in your loop design. Fill and bleed the loop according to the coolant and pump manufacturer's instructions, and verify there are no leaks at threaded connections before powering the system.

Usage recommendations

Use fans that match the radiator's 140 mm mounting and select airflow or static-pressure characteristics according to your case layout. Regularly inspect fittings and tubing for secure connections and perform scheduled maintenance on coolant condition and flow to preserve thermal performance and component longevity.
