Full-Copper Radiator for Custom Loops

The Alphacool NexXxos XT45 is a 120mm radiator built for DIY water-cooling enthusiasts who want maximum thermal density in a single-fan slot. Its chambers, fins and channels are all copper, while steel side panels and brass threads add structural rigidity. This construction targets builders who need every millimetre of cooling surface without stepping up to a larger footprint.

Six G1/4 Ports and 45mm Depth

Six G1/4-inch ports give flexible inlet and outlet routing for complex loop layouts, and the black finish keeps the aesthetic consistent in dark-themed builds. At 45mm thick the unit fits standard 120mm fan mounts, yet the 46mm overall depth means clearance must be checked against motherboard heatsinks or RAM modules. The 784g weight reflects the dense copper core and requires secure mounting.

120mm Single-Fan Form Factor Decides Fit

The 120mm width and 157mm length define whether this radiator fits your case’s designated radiator bracket; no larger or smaller variant is described here. Buyers planning dual-fan push-pull or multi-radiator arrays should verify that their chassis accepts a 45mm-thick single-fan unit before committing.

Questions about this item

What thread standard do the six ports use?

All six ports use G1/4" threads, so any standard G1/4 fitting will connect directly.

What are the exact case clearances needed for this 120 mm radiator?

The unit measures 157 mm long, 124 mm wide and 46 mm thick, so allow at least that space plus room for fittings and a fan.

How do I avoid trapping air when installing the radiator?

Mount it with the ports facing upward or sideways, then fill the loop slowly while tilting the case to push bubbles toward the highest port.
