Product information

Description

The Alphacool NexXxos ST30 Black Brass Copper Steel radiator block (124×400×30 mm) is a slim, full-copper-design heat exchanger intended for PC watercooling. Constructed with copper channel heads, fins and channels, and combined with brass and steel elements, this 30 mm-thick radiator offers high flow rates and compact installation length while maintaining compatibility with standard M3 mounting.

Advantages

The NexXxos ST30 combines a full-copper coolant path with brass and steel structural parts to improve thermal conductivity and durability. Split channel heads make the coolant path visible and support high flow, and a flat end chamber shortens overall length for easier installation. M3 threaded mounting points and protective inner edges prevent damage from over-tightened screws. Fin spacing is optimized for good performance with low to medium-speed fans.

Suitable for

Compact and mid-size PC watercooling loops
Systems requiring a slim 30 mm radiator thickness
Installations where a short overall radiator length is needed

How to use

Mount the radiator using M3 screws through the standard threaded holes; align fan and case mounting as required. Connect inlet and outlet fittings to the channel heads using appropriate G1/4 or specified thread adapters. If filling or venting is needed, use the designated vent/fill port or service the loop through your system’s fill solution. Ensure hoses and fittings are secure and the loop is pressure-tested before powering the system.

Usage recommendations

Use fans with low to medium speeds to achieve a balance of low noise and effective cooling, and choose fittings that minimize sharp angles to preserve the high flow characteristics of the NexXxos channel design.
