## Summary description

The Alphacool NexXxoS XT45 Radiator block features a robust design with brass, copper, and steel materials. Measuring 124 mm in width, 293 mm in depth, and 45 mm in height, it is optimized for liquid cooling systems. This radiator block ensures efficient heat dissipation, making it ideal for high-performance setups.

## Long description

The Alphacool NexXxos XT45 radiator block is a full-copper construction designed for liquid cooling systems and optimized for 120 mm fans. With copper chambers, fins and channels, this radiator provides improved thermal transfer and is available in a 45 mm thickness that balances cooling performance and installation space. The unit measures approximately 124 mm × 293 mm × 45 mm and comes in a black finish compatible with standard M3 mounting hardware.
Advantages
The NexXxos XT45 uses all-copper major components, including beveled copper chambers, to ensure even flow distribution across all channels and better heat dissipation compared with radiators that use mixed materials. It supports versatile mounting thanks to multiple fitting positions on inlet and outlet chambers (except on the ST30 variant), standard M3 thread points for fan and grill attachment, and an internal protective ledge that prevents damage if a screw is inserted too far. The fin layout is optimized for effective cooling at low to medium fan speeds, allowing quieter operation and broader fan compatibility.
Suitable for
Custom PC liquid cooling loops using 120 mm fans
High-performance desktop systems requiring efficient heat dissipation
Builds where moderate radiator thickness (45 mm) and flexible mounting are needed

How to use
Install the radiator into the loop using compatible fittings for the inlet and outlet ports; the chamber provides several fitting positions to reduce the need for angled adapters. Mount 120 mm fans using the standard M3 threaded holes and secure with appropriate screws, taking care that the internal protective ledge reduces the risk of fin damage if a screw is over-inserted. Connect tubing securely, fill and bleed the loop according to your coolant and pump manufacturer instructions, then verify flow and check for leaks before full operation.
Usage recommendations
For quieter operation and good thermal performance, pair the NexXxos XT45 with medium-speed or low-RPM 120 mm fans and avoid overly restrictive fittings; ensure fittings are compatible with the radiator’s multiple inlet/outlet positions to maximize flow.
