## Long description

The Alphacool NexXxoS ST25 Copper Steel 120mm is a compact, high-performance radiator block for liquid cooling systems. Constructed with copper end chambers, copper water channels and copper cooling fins combined with a steel structure, this radiator provides an efficient heat-dissipation foundation for PC cooling loops while maintaining a slim profile suitable for small form factor builds.
Advantages
All major hydraulic and thermal components of the NexXxoS ST25 are made from copper, which has higher thermal conductivity than aluminium and improves heat transfer. The radiator uses a carefully chosen fin density of 15 FPI and fins with small serrations to guide airflow and increase effective surface area, delivering strong cooling capacity while keeping airflow resistance and noise low. Its low height supports installation in Mini-PC and small form factor cases where space is limited.
Suitable for
120 mm fan-based liquid cooling loops
Mini-ITX and small form factor (SFF) PC builds
Systems requiring a low-profile radiator for space-constrained cases

How to use
Install the NexXxoS ST25 into a 120 mm fan mount position in your case or radiator bracket, ensuring fans are oriented for desired airflow direction through the fins. Connect the radiator to your loop with compatible fittings and tubing, fill the loop with coolant and purge air according to standard liquid-cooling procedures. Verify there are no leaks and confirm fan profiles and pump speed provide the intended balance between cooling performance and noise.
Usage recommendations
For optimal results, use 120 mm high-performance fans with moderate static pressure to take advantage of the 15 FPI fin density and serrated fins. Regularly inspect and maintain the cooling loop, and prefer corrosion-inhibited coolant compatible with copper and steel to protect materials over time.
