## Summary description

## Long description

The Alphacool NexXxoS ST30 is a compact 120 mm-series radiator block designed for custom liquid cooling systems. With dimensions of 124 × 172 × 30 mm and a durable copper-and-steel construction, the ST30 provides reliable heat transfer in a space-saving form factor. The unit is finished in black and accepts standard 120 mm fans and mounting hardware.
Advantages
The NexXxoS ST30 uses a full-copper main structure where the fins, channels and internal chambers are made of copper, which improves thermal conduction compared with radiators that use mixed materials. The X-Flow internal layout equalizes flow through all channels for more efficient heat exchange. Multiple connection positions on the chambers (except on the ST30 where options are reduced) minimize the need for angled fittings and simplify installation. Sturdy M3 threaded mounting points support common fan and grill attachments, and an internal protective ledge prevents damage if a screw is over-inserted. The fin spacing and design deliver good performance even with slow to medium-speed fans, allowing quieter operation and a wider choice of compatible fans.
Suitable for
Custom PC water cooling loops using 120 mm fans
Compact builds that require a low-profile 30 mm radiator
Systems where easy mounting and reduced angled fittings are preferred

How to use
Install the radiator in your water cooling loop using the standard inlet and outlet ports; ensure fittings and tubing are compatible with the available chamber positions. Mount 120 mm fans to the radiator using the M3 threaded holes and appropriate screws, taking care not to over-tighten. Connect the radiator between the water block and pump/reservoir as part of a closed-loop system, then perform leak testing and bleed any trapped air before normal operation.
Usage recommendations
For best balance of noise and cooling, pair the ST30 with slow to medium-speed 120 mm fans and use straight fittings where possible to maximize flow. Always pressure-test your loop after installation and avoid over-tightening screws into the radiator to prevent unnecessary strain on mounting points.
