NexXxoS ST30 480mm Radiator

The Alphacool NexXxoS ST30 is a 480mm liquid-cooling radiator built entirely from copper, including its chambers, fins and channels. Its X-Flow internal structure is designed for high flow rates through the heat exchanger. The unit ships as a single radiator with two screw plugs and mounting hardware. It is intended for custom-loop builders who want a full-copper heat exchanger in a 480mm length.

For custom-loop builders needing full copper

This radiator suits enthusiasts assembling a custom water-cooling loop who prioritise a heat exchanger made completely from copper for thermal performance. It is not for buyers who need an all-in-one cooler with integrated pump and fans, nor for systems that cannot accommodate a 480mm long radiator. It also does not suit users looking for aluminium-core radiators or units with different internal flow architectures.

Full-copper construction with X-Flow

The defining specification is the full-copper build where chambers, fins and channels are all copper rather than only the water paths. This material choice raises thermal conductivity across the entire radiator body. Combined with the X-Flow layout optimised for high flow rates, it determines whether the radiator meets the thermal and hydraulic requirements of a specific custom loop.

Questions about this item

How can I confirm the Alphacool NexXxoS ST30 480mm radiator is performing correctly after installation?

Monitor coolant temperatures under load; the full-copper construction including chambers and X-Flow design should deliver low delta-T at high flow rates.

What comes in the box with the Alphacool NexXxoS ST30 480mm radiator and what must I purchase separately?

Included are the radiator, two screw plugs and mounting hardware; fans, fittings, coolant and tubing are not supplied.

Which version of the Alphacool NexXxoS ST30 480mm radiator should I choose for my loop?

The ST30 480mm X-Flow model (14231) is a single 30 mm thick full-copper radiator optimised for high flow rates; select it when space allows a 480 mm length.
