In stock Ships by Tue, Nov 10 when paid today.
A 420mm copper radiator with integrated EZ fittings for simple tubing connections. Built for large cases and high-performance custom loops.
The core and fins are made entirely of copper for strong thermal conductivity. A steel frame adds structural rigidity. All visible surfaces, including the fin stack and cage, feature a black finish.
Integrated 16mm EZ fittings accept both hard and soft tubing without extra adapters. The unit mounts with standard M4 threads and fits three 140mm fans at 25mm or 30mm thickness.
The 420mm length provides a large cooling surface area with a fin density of 19 FPI. Two G1/4 ports handle inlet and outlet flow. No RGB lighting is included.
