Radiator Alphacool 14439 Brass Copper Steel Black 124mm Width

The Alphacool 14439 radiator is a high-conductivity cooling component made from brass, copper and steel with a black finish. Part of Alphacool's NexXxoS Full Copper family lineage, this 124 mm wide radiator uses a dense internal structure and multiple water channels to improve contact between coolant and fins, increasing heat transfer efficiency while fitting typical 120 mm fan mounting arrangements. It is intended for installation in PC water-cooling loops where compact dimensions and reliable heat dissipation are required.

Advantages

This radiator combines copper-based water-carrying parts and fins with a compact, condensed fin arrangement to increase the number of fin rows and water channels in the same footprint. The design improves heat transfer compared with conventional NexXxoS models and supports higher thermal loads. Integrated G1/4" inlet/outlet threads, a dedicated fill/drain port and included mounting screws simplify installation. Protective plates under the mounting holes prevent damage to fins and channels, while recessed patented screw plugs allow the unit to sit flush during assembly.

Suitable for

• Custom PC water-cooling loops with 120 mm fan mounts
• Systems requiring improved heat dissipation in a compact radiator (124 mm width)
• High-power CPUs or components where stable coolant temperatures are needed

How to use

Mount the radiator in your case at a location compatible with 120 mm fans using the supplied screws. Connect the water-cooling loop to the G1/4" inlet and outlet threads; use the fill/drain port for filling and bleeding the circuit. Ensure fans are oriented for the desired airflow direction and that screws are tightened only until the protective plates engage to avoid damaging fins. Follow the coolant and loop component manufacturers' instructions when assembling and testing the loop.

Recommendations

Use corrosion-safe coolant compatible with copper and brass. During first startup, perform a leak test and run the loop outside the case or with minimal power to confirm there are no leaks. For sustained high heat loads, increase airflow through higher-performance fans and monitor coolant temperatures to ensure stable operation.
