Radiator Alphacool 14441 Brass Copper Steel Black 144mm 314.5mm 45mm

The Alphacool 14441 NexXxoS HPE Full Copper radiator continues Alphacool's long-standing NexXxoS series tradition of using copper for water-carrying parts and cooling fins to achieve high thermal conductivity. This 144mm radiator in a black finish is engineered to increase coolant contact with fins via a denser internal channel structure, improving heat transfer compared with conventional NexXxoS models. The HPE design can deliver several degrees better cooling under heavy loads, making it suitable for demanding PC liquid-cooling loops. The unit includes connection and mounting hardware and a dedicated fill/drain port for easier maintenance.

Advantages

The NexXxoS HPE Full Copper construction provides increased thermal conductivity thanks to copper water channels and fins. A condensed internal structure increases the number of water channels and fin rows, enlarging the coolant-to-fin contact area and improving heat transfer. Test comparisons against standard NexXxoS radiators show measurable temperature reductions under high waste-heat conditions. Integrated safety plates under mounting holes protect fins and channels from screw damage, and Alphacool's patented recessed screw plugs allow flush installation in cases.

Suitable for

• High-performance PC liquid-cooling loops requiring efficient heat dissipation
• Systems with high CPU or GPU waste heat where lower coolant temperatures are needed
• Custom builds where compact 144mm radiators are required

How to use

Install the radiator into a compatible case mounting location using the supplied screws for both radiator and fan attachment. Connect the cooling loop using G1/4" fittings on the provided IN/OUT ports and use the fill/drain port to fill the circuit or remove coolant during maintenance. Ensure screws are tightened to a safe depth; protective plates are provided under mounting holes to reduce the risk of damaging internal fins and channels. Use compatible fans and mounting orientation to optimize airflow through the fins.

Recommendations

For best results in high-waste-heat systems, pair the NexXxoS HPE radiator with high-static-pressure fans and follow a proper fill and bleed procedure. Check fittings for tightness after initial operation and perform routine inspections of the coolant level and connections.
