Hladilnik Alphacool NexXxoS ST30

The Alphacool NexXxoS V.2 radiator is an evolution of the NexXxoS V.1 series and belongs to Alphacool's range of high-end full-copper radiators. Finished in a modern white design, the NexXxoS V.2 is built for integration into custom water cooling systems and combines an all-copper water path with technical refinements for reliable thermal performance.

Advantages

All water-bearing components of the radiator—the pre-chambers, cooling fins and cooling channels—are manufactured from pure copper, while threaded inserts are brass and the outer casing is sheet steel. Copper’s higher thermal conductivity is used throughout to improve heat transfer compared with aluminium designs. The radiator features a 15 FPI fin density with serrated fins to guide airflow, increase heat dissipation and reduce flow noise. Alphacool’s patented recessed screw plugs ensure flush mounting without protrusions that could prevent a clean installation. Multiple inlet/outlet positions and a dedicated fill/vent port provide flexible connection options. Protective plates under the fan and mounting screw holes prevent damage to fins and water channels during assembly.

Suitable for

• Custom PC water cooling loops
• High-performance CPU and GPU cooling setups
• Configurations requiring multiple inlet/outlet orientations

Key specifications

• Material (water-bearing parts): pure copper
• Outer casing: sheet steel; threaded inserts: brass
• Fin density: 15 FPI with serrated fins
• Patented recessed screw plugs for flush mounting
• Multiple IN/OUT options per side and a fill/vent port

How to use

Install the NexXxoS V.2 radiator in your case using the standard radiator mounting points. Choose the IN and OUT ports that match your loop routing; the radiator offers two port positions on each side. Use the fill/vent port for initial filling and for draining the loop if required. When mounting fans or securing the radiator to the case, align screws with the protective plates to avoid penetrating the fins or water channels. Follow the rest of your loop assembly and leak-testing procedures before powering the system.

Recommendations

Use copper-compatible coolant and corrosion inhibitors to maintain long-term performance. Ensure correct fan orientation and sufficient airflow through the 15 FPI fin array for optimal cooling results.
