Overview

A 120mm multiport radiator built for custom liquid cooling loops. It suits builders who want low restriction, flexible routing, and strong thermal performance at low fan speeds.

Core Design and Materials

The radiator uses sixteen 2mm copper tubes and high-grade non-louvered copper fins at 18 FPI. This construction balances thermal transfer and air resistance for strong performance even with low-speed fans. The core is pressure tested to 1 bar.

Port Layout and Routing

Five G1/4 ports are integrated into the aluminum end caps. Four ports sit on one end tank for inlet and outlet flexibility, while a fifth port on the opposite end serves draining and air bleeding. Modular plugs let you reconfigure port positions for cleaner tube runs.

Loop Compatibility and Mounting

Low flow and airflow restriction allow multiple units on a single D5 or DDC pump without added stress. The radiator accepts three 120mm fans via standard M4 threads and includes black Philips round-head screws. EK recommends fans with sealed-edge frames for best results.

Build Quality and Modularity

Extruded aluminum end caps with a silver finish join stainless-steel side plates coated in semi-gloss black paint. Fins carry a black matte coating with high thermal conductivity. The modular design simplifies disassembly for painting or custom modifications.
