NexXxoS ST30 Full Copper X-Flow 360mm Ψυγείο

Alphacool NexXxoS ST30 Full Copper X-Flow 360mm radiator designed for PC liquid cooling systems. The NexXxoS series uses full-copper construction for its main parts — fins, channels and chambers — to improve thermal performance. The ST30 model is available in the 120mm fan series form factor and offers multiple thickness options to suit different builds and airflow requirements.

Advantages

The full-copper construction improves heat transfer compared with radiators that use mixed materials. The X-Flow design ensures simultaneous flow through all available channels, which supports high flow rates and uniform coolant distribution. Mounting is versatile: the chamber provides multiple inlet/outlet positions (note: not all positions apply to the NexXxoS ST30), and M3 threaded holes allow standard fan and grill installation. An internal protective ledge prevents damage from over-inserted screws. The fin spacing and fin design make the radiator efficient even with slow to medium-speed fans, enabling lower noise operation and wider fan compatibility.

Suitable for

• Custom PC liquid cooling loops
• High-flow cooling systems requiring even coolant distribution
• Builds that prioritize low-noise operation with slow/medium-speed fans

How to use

Install the radiator in your PC chassis using compatible 120mm fan mounts and M3 screws. Connect inlet and outlet fittings according to your loop layout, keeping in mind the available chamber positions; fewer angled fittings improve flow. Use appropriate tubing and secure fittings to prevent leaks. When mounting fans, ensure screw length does not exceed the protective ledge depth to avoid contact with fins. Fill, bleed and test the loop following standard liquid-cooling procedures before powering the system.

Recommendations

For best results, pair the NexXxoS ST30 360mm radiator with low-to-medium speed fans to balance cooling performance and noise levels. Use quality fittings and maintain a clean loop to preserve thermal efficiency over time.
