Radiator Alphacool 14377 Brass Copper Steel Black 124mm Width

The Alphacool 14377 radiator is a full-copper style cooling radiator engineered for efficient heat dissipation in PC liquid-cooling loops. Constructed from high-conductivity metals and finished in black, this compact 124 mm wide radiator is compatible with systems that use 120 mm fans and provides a reliable thermal solution for CPUs and other high-heat components.

Advantages

The NexXxoS HPE design increases the number of water channels and copper fins compared with earlier NexXxoS models, improving heat transfer by bringing a larger volume of coolant into direct contact with the fins. The denser internal structure and increased fin rows make more effective use of the cooling surface, delivering measurable performance gains versus conventional designs. The radiator includes built-in protective plates under mounting holes to prevent damage to fins and water channels and uses recessed patented screw plugs for flush mounting.

Suitable for

• PC liquid-cooling loops for CPUs and GPUs
• Compact builds requiring a 124 mm width radiator with 120 mm fan support
• Systems needing improved heat dissipation in high-wattage setups

How to use

Install the radiator in your case using the supplied mounting screws and mount 120 mm fans to the radiator in the desired push or pull configuration. Connect the liquid-cooling loop using the G1/4" threaded IN/OUT ports and use the dedicated fill/drain port for filling or draining the loop. Ensure fittings are tightened to proper torque and that the radiator is mounted securely with the protective plates positioned over the mounting holes to avoid compressing the fins.

Recommendations

For best results, pair this radiator with fans that provide sufficient airflow at the intended fan speed and verify compatibility with your case layout. When replacing or upgrading radiators, compare performance under your typical ambient conditions; the HPE design provides larger performance gains at higher ambient temperatures and fan speeds.
