## Long description

The Alphacool NexXxos XT45 heatsink is a liquid-cooling radiator designed to provide effective heat dissipation for high-performance computer systems. Constructed with copper main elements and a steel structure, the radiator comes in a black finish and features a compact footprint (223 mm width, 45 mm depth, 182 mm height) that balances cooling capacity with installation flexibility.
Advantages
The NexXxos series uses full-copper main elements including fins, channels and pre-chambers to improve thermal performance compared with radiators that only use copper in part. Separate pre-chambers and a design optimised for high flow reduce hydraulic resistance and increase system-wide cooling efficiency. Multiple inlet/outlet positions at the pre-chamber (three options at each side) and a shallow end chamber simplify mounting and reduce the need for angled fittings, enabling installation in tighter cases. M3 threads for fans and trims, an internal screw-stop to protect fins and an available 1/4" bleed port on select models add practical installation and maintenance benefits.
Suitable for
Custom liquid cooling loops in desktop PCs
High-performance gaming and workstation systems
Compact cases where space for internal radiators is limited

How to use
Install the NexXxos XT45 into your custom liquid cooling loop following standard radiator mounting procedures. Fasten fans and radiator trims using the M3 threads provided. Position inlet and outlet fittings using the available mounting options on the pre-chamber to minimise bends and maintain high flow. If present, use the 1/4" bleed port for filling and venting the loop. Ensure connections are tightened to the component specifications and test the loop for leaks before powering the system.
Usage recommendations
Use medium- to low-speed fans to achieve efficient cooling with reduced noise, as the fin spacing is optimised for good performance with slowly to moderately rotating fans. When installing in tight spaces, take advantage of the multiple inlet/outlet positions to minimise angled fittings and improve flow.
