Radiator Alphacool 14468 Brass Copper Steel Black 124mm 151.5mm 30mm

The Alphacool NexXxoS HPE Full Copper radiator builds on over a decade of NexXxoS experience, using pure copper for all water-carrying parts and cooling fins to maximize thermal conductivity. This compact radiator variant increases the number of water channels and fin rows to put more coolant in direct contact with cooling surfaces, improving heat transfer and overall performance. The model corresponds to the Alphacool 14468 dimensions and materials: brass and steel components with copper cooling elements, finished in black and sized to fit compact installations.

Advantages

The condensed internal structure increases the number of water channels and shortens fin rows, providing substantially improved heat transfer compared with conventional NexXxoS radiators. Tests indicate a possible thermal performance gain (lower coolant temperature) of around 4.5 K under the referenced test conditions and up to 6 K at higher ambient temperatures or fan speeds. Pre-installed protective plates under mounting holes prevent screw damage to fins and water channels. Patented recessed screw plugs enable flush mounting without protrusions, simplifying installation.

Suitable for

• Compact PC cooling loops where high thermal conductivity is required
• Custom water-cooling systems for CPUs and small form-factor GPUs
• Environments with elevated waste heat where efficient dissipation is needed

How to use

Install the radiator into the case using the supplied screws for either intake or exhaust fan mounting. Connect the cooling loop using the two G1/4" ports for inlet and outlet; use the fill/drain port for filling and bleeding the loop. Ensure fans are oriented for the desired airflow direction and that screw plugs are fully recessed for a flush fit. Follow standard water-cooling safety procedures: tighten fittings to the manufacturer’s torque recommendations and perform a leak test before powering system components.

Recommendations

The radiator performs best with adequate airflow from quality fans and a properly filled, bled cooling loop. For compact builds, check internal clearance against the stated dimensions (124 × 151.5 × 30 mm). Regularly inspect mounting points and fittings for tightness, and replace cooling fluid according to your coolant manufacturer’s guidance.
