Overview

A black 420mm copper radiator built for custom water cooling loops. It fits high-end systems that need dense fin performance and multiple port options.

Construction and Materials

The core uses copper for heat transfer while the end tanks are brass with stainless steel reinforcement. Every visible surface including the fins, cage, and tanks receives a black coating.

Flow Design and Ports

A multipass internal structure directs coolant across the fin stack multiple times. Five G1/4 inch internal threads provide flexible inlet and outlet routing for complex loop layouts.

Fan Compatibility

The frame accepts up to six 140mm fans mounted with standard M3 threads. The 45mm thickness and 16 FPI density are suited for moderate to high static pressure fan configurations.

Testing and Dimensions

Each unit is pressure tested to 0.8 bar at the factory. Overall measurements are 455.5mm long, 144mm wide, and 45mm thick with a weight of 1533 grams.
