Radiator Aquatuning GmbH 1025507 Copper Black White 124mm 30mm

The Alphacool HPE Full Copper radiator continues Alphacool's long-standing Full Copper series and is built entirely from copper for both water-bearing parts and cooling fins. This compact model (124 mm × 30 mm) offers increased internal density compared with previous NexXxoS radiators: more water channels and additional, shortened fin rows place a larger water volume in direct contact with the cooling surface, improving heat transfer and enabling up to 4.5 K better cooling in standard tests and up to around 6 K under higher ambient temperatures and fan speeds. The radiator includes two G1/4" threaded IN/OUT connections in the pre-chamber area, a dedicated fill/drain port on the opposite side, and all necessary screws for fan and case mounting. Patented recessed screw plugs and protective plates under mounting holes reduce risk of damage during installation.

Advantages

The full-copper construction ensures high thermal conductivity and long-term durability while the denser internal structure and increased fin density improve heat-transfer efficiency compared with conventional NexXxoS designs. Recessed patented screw plugs allow flush installation, and protective plates beneath mounting holes prevent screws from penetrating and damaging fins or water channels. The included mounting screws simplify installation in typical PC cases.

Suitable for

• Compact PC water-cooling loops where efficient heat dissipation is required
• High-temperature or high-fan-speed cooling setups that benefit from improved thermal performance
• Systems needing reliable, durable radiator components made from copper

How to use

Install the radiator into the case using the supplied screws, mounting it where clearance for a 124 mm × 30 mm unit is available. Connect the cooling loop to the two G1/4" IN/OUT ports and use the fill/drain port for filling or draining the loop. Ensure fittings are tightened to specification and that the recessed screw plugs remain flush with the radiator surface. During initial fill, run the pump at low speed and check for leaks before normal operation.

Recommendations

For best results, use matched copper or nickel-plated copper fittings and clean coolant compatible with copper components. Monitor temperatures during the first hours of operation to verify expected performance gains; higher ambient temperatures and increased fan speeds typically maximize the HPE radiator's advantage over conventional NexXxoS models.
