Radiator Alphacool 14474 Brass Black 173.5mm x 144mm x 45mm

The Alphacool 14474 Brass Black radiator is a compact full-metal cooling radiator designed for computer liquid-cooling loops. Constructed from brass and finished in black, it implements Alphacool's NexXxoS HPE design principles—dense internal water channels and multiple short fin rows—to increase the contact area between coolant and fins and improve heat transfer. The radiator's dimensions are 173.5 mm × 144 mm × 45 mm, making it suitable for tight builds where efficient heat dissipation is required.

Advantages

The condensed internal structure increases the number of water channels and fin rows, providing improved thermal conductivity and more effective use of the cooling surface compared with conventional designs. Integrated inlet/outlet ports and a dedicated fill/drain port simplify loop filling and maintenance. Protective plates beneath mounting holes guard the fins and channels from screw damage, and recessed patented screw plugs allow the radiator to sit flush during installation.

Suitable for

• Compact desktop PCs with custom liquid-cooling loops
• High-performance workstations where space is limited
• Systems requiring reliable thermal management for CPUs or GPUs

Key specifications

• Material: brass construction with black finish
• Design: high-performance engine (HPE) dense internal channel and fin structure
• Dimensions (W × D × H): 173.5 mm × 144 mm × 45 mm
• Threaded connections: two inlet/outlet ports with G1/4" threads in the pre-chamber area
• Additional port: dedicated fill/drain port on the opposite side
• Included hardware: screws for case and fan mounting
• Mounting protection: protective plates under mounting holes

How to use

Install the radiator in the case using the supplied screws, ensuring the protective plates align with mounting holes to avoid damaging fins. Connect the cooling loop using G1/4" threaded fittings on the inlet/outlet ports and use the fill/drain port for filling and bleeding air from the circuit. Verify secure, leak-free connections before powering the system and run the loop to achieve stable temperatures.

Recommendations

For optimal performance, pair the radiator with appropriately rated fans and ensure adequate airflow through the fin stack. When used in compact or high-heat systems, monitor coolant temperatures and consider higher airflow or multiple radiators if waste heat is substantial.
