Alphacool NexXxos XT45 480mm Radiator

The Alphacool NexXxos XT45 is a full copper radiator built for custom liquid cooling loops. It measures 522mm long, 124mm wide and 46mm thick, with a 45mm core depth and six G1/4 inch ports. The construction uses copper for the chambers, fins and channels, while the side panels are steel. It weighs 1897 grams and carries a black finish.

Builders planning high heat loads

This radiator suits enthusiasts assembling a custom loop who need maximum surface area from a quad 120mm fan layout. The full copper internals and separated chambers are designed for strong thermal transfer. Buyers who only have space for a thinner profile or a shorter radiator should look at something else, as the 46mm thickness and 522mm length demand generous case clearance.

45mm core depth with full copper chambers

The single specification that decides fit is the 45mm core depth combined with copper chambers, fins and channels throughout. This construction drives the thermal capacity of the 480mm length. Verify that your case can accommodate the 522 by 124 by 46mm envelope and that your loop uses G1/4 fittings before purchasing.

Questions about this item

What case clearance is needed for the 522 mm length and 46 mm thickness?

The radiator measures 522 mm long, 124 mm wide and 46 mm thick, so your chassis must provide at least that much internal space plus room for fans on either side.

How are the six G1/4 ports used during loop assembly?

Connect tubing or fittings to any two opposite ports for inlet and outlet; plug the remaining four ports with the supplied G1/4 stop plugs before filling the loop.

When should the coolant be replaced in this full-copper radiator?

Drain and refill the loop every 12 to 18 months, or sooner if the fluid becomes cloudy or shows particulate buildup inside the copper channels.
