## Summary description

Alphacool NexXxoS XT45 radiator block made of copper with black finish. Dimensions 124 × 275 × 45.5 mm; designed for liquid cooling systems. Provides a metal copper cooling surface for heat dissipation in PC or custom liquid loops. Suited for integration into compact or mid-size cooling configurations where a 45.5 mm thickness is required.

## Long description

Alphacool NexXxoS XT45 radiator block in copper with a black finish is a compact liquid-cooling radiator designed for PC and custom loop applications. Measuring 124 × 275 × 45.5 mm, this unit provides a full copper cooling surface including end chambers, water channels and fins, enabling efficient heat transfer in confined or mid-size cooling layouts that require a 45.5 mm thickness.
Advantages
The radiator uses pure copper for all flow-relevant components, delivering higher thermal conductivity compared to aluminium and improving overall heat dissipation. Its 15 FPI fin density is chosen to balance airflow resistance and cooling performance, while small directional flaps on the fins create controlled turbulence to increase heat exchange without significant noise. Patented countersunk screw plugs allow flush mounting for a cleaner installation, and integrated protective plates under mounting holes prevent screws from damaging internal fins or channels. Multiple connection ports include dedicated inlet, outlet and a fill/vent port to simplify filling and draining the loop.
Suitable for
Compact or mid-size PC builds requiring a 45.5 mm thick radiator
Custom water-cooling loops for CPUs and GPUs
Systems where full-copper radiators are preferred for higher thermal conductivity
Environments needing a radiator that supports flush mounting and easy maintenance
Key specifications
Material: pure copper for end chambers, water channels and fins
Finish: black
Dimensions: 124 × 275 × 45.5 mm (width × length × thickness)
Fin density: 15 fins per inch (FPI)
Thickness class: XT45 (45 mm series)
Airflow features: directional fin flaps to improve heat exchange and reduce flow noise
Mounting protection: protective plates under mounting holes to prevent internal damage
Connection options: inlet, outlet and additional fill/vent port
How to use
Install the radiator in a compatible location inside the case or external mount using the standard fan and radiator mounting points. Ensure the radiator orientation allows access to the inlet, outlet and fill/vent port for easy loop filling and maintenance. Connect tubing to the inlet and outlet ports using appropriate fittings and secure them according to the fitting manufacturer’s instructions. When mounting fans, use the countersunk screw plugs to achieve a flush installation and tighten screws to the recommended torque to avoid compressing the protective plates.
Usage recommendations
For optimal cooling performance, pair the XT45 radiator with fans that provide moderate static pressure and sufficient airflow, and configure fan speeds to balance noise and temperature. Use corrosion-inhibiting coolant compatible with copper components and perform routine loop maintenance including periodic draining and visual inspection of fittings and mounting points.
