Alphacool NexXxos XT45 V.2 140mm Radiator

The Alphacool NexXxos XT45 V.2 is a 140mm liquid-cooling radiator built for custom-loop enthusiasts who want maximum thermal capacity in a single-fan footprint. Its solid-copper construction targets builders chasing the highest heat-dissipation potential from a compact 140mm form factor.

Five G1/4 ports and countersunk screw plugs

Five G1/4 threaded ports give flexible inlet, outlet and bleed-point placement so the radiator can be mounted in any orientation. Countersunk screw plugs sit flush with the end chambers, preventing tube interference and keeping cable routing clean in tight builds.

12 FPI fin density on a 45.5mm core

A 12 fins-per-inch density across the 45.5mm-thick copper core balances airflow resistance with surface area, allowing a single 140mm fan to move sufficient air at moderate speeds. The all-copper water channels and fins transfer heat efficiently without demanding extreme fan RPM, keeping loop noise low under typical loads.

Questions about this item

What thread standard do the five G1/4 ports use and what does it limit in practice?

All five ports use G1/4 BSPP threads, so every fitting, plug or adapter must match that thread; the standard caps the outer diameter of any connected tubing or block to the G1/4 bore size.

What are the exact external dimensions I need to clear for this 140 mm radiator?

The radiator measures 177 mm wide, 143 mm deep and 45.5 mm thick, so your case must provide at least that footprint plus clearance for the chosen fan.

How is the radiator mounted and which step is most often missed?

Use the countersunk screw plugs to secure the unit through the end chambers; the step people miss is installing the extra G1/4 bleed port on the opposite end chamber before locking the radiator in place.
