480 mm Full-Copper Radiator for Custom Loops

The Alphacool NexXxos ST30 is a 480 mm radiator built for DIY liquid-cooling systems. Its chambers, channels and fins are all copper, while the side panels are steel and the threads are brass. Two G1/4 ports provide the inlet and outlet connections. The unit measures 552 by 124 by 30 mm and weighs 1226 g.

Quad 120 mm Fan Mounting Constraints

The radiator accepts four 120 mm fans in a push, pull or push-pull arrangement. Its 30 mm core thickness limits fin density, so airflow restriction remains low but total heat capacity depends on the fans you choose. The 552 mm overall length requires a case with a matching 480 mm mounting area; shorter chassis cannot accommodate it.

Straightforward Installation with Clearance Checks

Installation uses standard G1/4 fittings and the included mounting holes for four fans. The most common issue is discovering that the 552 mm length conflicts with motherboard heatsinks, drive cages or front-panel cables. Verify internal clearance before purchase, and allow space for tubing bends at the port ends.

Questions about this item

Should I choose the 480 mm version with four 120 mm fan slots or a smaller radiator for my loop?

The 480 mm length and four 120 mm fan positions give maximum surface area for heat dissipation, ideal for high‑heat loads or multiple components in one loop.

How does the full‑copper construction affect real‑world cooling performance?

Copper chambers, fins and channels transfer heat faster than mixed‑metal designs, so coolant temperatures drop more quickly under sustained load.

What does the G1/4 thread standard mean for fitting compatibility?

G1/4 is the universal water‑cooling thread; any standard G1/4 compression or barb fitting will seal directly without adapters.
