Radiator Alphacool 14469 Brass Copper Steel Black 124mm 511.5mm 30mm

The Alphacool NexXxoS HPE Full Copper radiator continues Alphacool's long-standing NexXxoS line by using copper water channels and cooling fins to achieve very high thermal conductivity. This model increases the density of internal channels and fin rows so a larger volume of coolant contacts the fins directly, improving heat transfer compared with earlier NexXxoS radiators. The HPE design yielded measured improvements in temperature reduction in comparative testing against a conventional NexXxoS radiator when used with common PC cooling components.

Advantages

The condensed internal structure increases the number of water channels and fin rows, which enhances heat transfer and makes more efficient use of the available cooling surface. The radiator includes G1/4" threaded inlet/outlet connections, a dedicated fill/drain port, protective plates under mounting holes to prevent damage to fins and channels, and recessed patented screw plugs for flush installation. All required screws for case and fan mounting are supplied.

Suitable for

• Custom liquid cooling loops in desktop PCs
• High-performance CPU and GPU cooling setups
• Systems requiring compact, high-conductivity radiators

How to use

Mount the radiator in your PC case using the included screws and install compatible 120 mm fans on the radiator faces. Connect the cooling loop using standard G1/4" fittings to the inlet and outlet ports and use the fill/drain port for filling and bleeding the loop. Ensure connections are tightened to avoid leaks and that protective plates under mounting holes remain in place to prevent damage to fins. Follow the rest of your liquid-cooling component manufacturers' instructions for pump, reservoir and coolant selection.

Recommendations

Use high-quality G1/4" fittings and appropriate coolant; when testing the loop, perform a leak test outside powered components. The HPE radiator performs best with sufficient airflow from 120 mm fans and in systems that can benefit from increased fin density and direct coolant-to-fin contact.
