Alphacool NexXxoS ST30 140mm Radiator

The Alphacool NexXxoS ST30 is a full-copper radiator designed for custom water-cooling loops. Its chambers, fins and channels are all made from copper for improved thermal transfer. The unit targets enthusiasts building high-performance liquid cooling systems. It ships as a single radiator with mounting hardware included.

Check 140mm fan mounts and screw clearance

Verify that your case offers 140mm fan mounting positions with enough depth for a 30mm thick radiator plus fans. Ensure the supplied M3 screws in 30mm and 35mm lengths suit your chosen fan thickness and frame design. Confirm the loop uses G1/4 threads for the radiator ports before ordering.

Suits single-radiator custom loops needing full

Builders who want an all-copper heat exchanger in a 140mm form factor will benefit from the material consistency. Users requiring multiple radiators, larger surface areas or different port configurations should look at other sizes or multi-radiator kits.
