Product information

Description

The Alphacool NexXxos ST30 radiator block is a compact liquid-cooling heat exchanger engineered for PC cooling loops. Constructed using copper, brass and steel with a black finish, the ST30 is designed for 140 mm fans and offers a 30 mm thickness that balances cooling capability and installation space. Its internal separated chambers and flat chamber design provide directed coolant flow and reduced overall length for flexible mounting in constrained enclosures.

Advantages

All main parts of the NexXxos ST30 are made from copper/brass materials where applicable, improving thermal conductivity compared with radiators that use mixed metals. The separated chambers promote high flow rates and consistent coolant distribution, while the flat chamber profile reduces installed depth. Multiple fitting positions on inlet and outlet ports increase mounting options and reduce the need for angled fittings. Standard M3 mounting threads, internal screw-protection ledge and fin spacing optimized for slow to medium fan speeds further simplify installation and allow quiet operation.

Suitable for

Custom PC water-cooling loops requiring a compact 140 mm radiator
Builds with limited internal depth where a 30 mm thickness is preferred
Systems where quiet operation with low-to-medium fan speeds is desired

How to use

Install the Alphacool NexXxos ST30 in your loop where a 140 mm radiator fits, securing it using the standard M3 threaded holes. Connect the inlet and outlet with appropriate G1/4" fittings or adapters; the design provides multiple fitting positions to reduce angled fittings and improve flow. When mounting vertically, use the 1/4" screw port (if present on your model) for de-aeration or filling in combination with compatible fill ports. Ensure fans are oriented to provide the desired airflow direction and that fan screws are not over-inserted thanks to the internal protective ledge.

Usage recommendations

For optimal performance and low noise, pair the ST30 with slow to medium-speed 140 mm fans and maintain adequate loop flow. When installing in tight enclosures, plan fitting orientation in advance to take advantage of the multiple inlet/outlet positions and the reduced overall depth.
