## Long description

The Alphacool NexXxoS XT45 Full Copper X-Flow heatsink is a full-copper radiator designed for water-cooling systems, combining a robust build and a layout optimised for high flow rates. All main components — fins, channels and chambers — are made of copper to improve thermal performance. The radiator is available in the popular 120 mm series width with a thickness of 45 mm, and its dimensions and materials make it suitable for demanding cooling tasks in custom liquid-cooling loops.
Advantages
The X-Flow design uses bevelled copper chambers and parallel channels to distribute water evenly across all fins, improving heat transfer compared with conventional radiators. Full-copper construction of fins, channels and chambers increases thermal conductivity. Multiple inlet/outlet positions on the chamber (except on the NexXos ST30) reduce the need for angled fittings and simplify installation. Standard M3 threaded mounting points allow flexible fan and grill attachment. An internal protective ledge prevents accidental screw damage to the fins. Fin spacing is optimised to perform well with low and medium-speed fans, enabling quieter operation and a wider choice of compatible fans.
Suitable for
Custom water-cooling loops for high-performance PCs
Radiator replacement or upgrades in 120 mm series builds
Systems requiring high flow rates and efficient heat dissipation

How to use
Mount the NexXxoS XT45 in your loop using the standard M3 threaded holes to attach fans or grills. Choose inlet and outlet positions on the chamber to minimise angled fittings and maintain high flow. Connect tubing to the selected ports and secure fittings according to the fitting manufacturer's instructions. Fill and bleed the loop following your normal water-cooling procedure, then test for leaks and proper flow before regular operation.
Usage recommendations
Use medium to low-speed fans for a balance of airflow and low noise; check compatibility with your pump and loop layout to ensure adequate flow. Avoid overtightening screws to maintain the protective ledge’s effectiveness.
