Alphacool NexXxoS ST30 Full Copper 280mm jäähdytin V.2 14280

Full copper construction across fins, tubes, and pre-chambers delivers exceptional heat dissipation for high-performance custom loops, while the 30mm slim profile fits easily into space-constrained builds.

Overview

The Alphacool NexXxoS ST30 Full Copper 280mm Radiator V.2 is engineered for enthusiasts who demand maximum cooling efficiency without sacrificing compatibility. Supporting dual 140mm fans, this radiator offers a substantial surface area for heat exchange, making it ideal for overclocked CPUs and GPUs. The V.2 revision brings refinements to fin geometry, optimizing airflow for low-speed fans and reducing noise while maintaining excellent thermal performance.

What stands out

• Full copper core (fins, tubes, and pre-chambers) ensures superior thermal conductivity and long-term corrosion resistance.
• Slim 30mm thickness allows installation in tighter cases while still delivering high cooling capacity.
• Six G1/4" ports: four for loop integration and two dedicated fill/drain/sensor ports for convenient maintenance and monitoring.
• Integrated screw protection plates prevent accidental damage to the radiator core during fan installation.
• Pressure tested to 0.8 bar (11.6 PSI) for leak-free reliability.
• Matte black finish complements any build aesthetic.
