Alphacool NexXxoS XT45 Full Copper Dual 80mm Radiator 160mm 45mm

Alphacool NexXxoS XT45 Full Copper Radiator

The Alphacool NexXxoS XT45 is a full copper liquid cooling radiator designed for custom loop builders who want maximum thermal conductivity. Every main component, including the chambers, fins and channels, is manufactured from copper rather than brass. It uses a dual 80mm fan layout with a 160mm length and 45mm thickness. G1/4 threads provide standard fitting compatibility.

Upgrade from brass chamber radiators

This radiator replaces designs that only use copper for fins and channels while keeping brass end tanks. The full copper construction improves heat transfer across the entire coolant path. The jump is worth it when you are building a high heat load loop and want the material advantage across every internal surface. Separated chambers give the coolant a clear flow direction.

Suits custom loop enthusiasts seeking full copper

It suits builders who prioritise the thermal benefit of copper chambers and are planning a dual 80mm fan configuration. Buyers who need different fan sizes, larger core dimensions or integrated pump and reservoir units should look at other options. The package includes M3 mounting screws in 30mm and 35mm lengths for installation flexibility.
