Alphacool NexXxoS XT45 420 mm Radiator

The Alphacool NexXxoS XT45 is a full-copper water-cooling radiator built for custom loops. Its chambers, fins and channels are all made from copper to improve thermal transfer. The X-Flow internal structure is designed for high flow rates. It fits three 140 mm fans in a 420 mm length.

Suits high-flow custom loops; not for tight spaces

This radiator suits builders who want a full-copper heat exchanger with an X-Flow layout for unrestricted coolant movement. It is not for cases that cannot accommodate a 420 mm radiator or three 140 mm fan slots. Buyers needing a smaller footprint should look at shorter models.

420 mm length with three 140 mm fan slots

The decisive specification is the 420 mm radiator size combined with three 140 mm fan slots. This dimension determines whether the unit fits your chassis and matches your planned fan configuration. Verify case clearance before purchase.

Questions sur cet article

What G1/4 thread standard do the X-Flow ports follow, and what flow rate does it cap in practice?

The X-Flow radiator uses standard G1/4 threads; the bevelled chamber design removes internal restrictions so flow is limited only by your pump and tubing, not by the radiator itself.

What case clearance and fan mounting pattern does the 420 mm XT45 require?

It needs 420 mm of straight rail space plus 45 mm thickness, and accepts three 140 mm fans on 140 mm centres with the included mounting hardware.

How do the two screw plugs supplied with the XT45 install, and which port do builders often leave open by mistake?

Fit one plug into each unused chamber port with a G1/4 wrench; the most common error is forgetting the second plug on the opposite end, leaving a leak path.
