Overview

A 420mm full copper radiator built for custom water cooling loops. It fits large towers and handles high-end hardware loads.

Design and Materials

Every heat transfer surface uses copper, including fins, channels, and header tanks. The black finish covers the steel frame and copper surfaces for a uniform look. At 466mm long, 144mm wide, and 45mm thick, the unit requires a spacious case.

Cooling Performance

Fin density is set at 12 FPI to deliver strong heat dissipation even with low static pressure fans. The multipass flow path increases coolant contact time. Testing confirms the radiator holds pressure up to 0.8 bar.

Connectivity and Mounting

Six standard G1/4-inch threads accept common fittings for loop integration. A seventh G1/4 port is positioned for fill and drain convenience. Three 140mm fans mount directly to the radiator using M3 threads.

Usage Notes

Transparent coolants are recommended to prevent deposits that can clog the fine copper channels. Pastel or opaque fluids may cause buildup and reduce long-term performance.
