Overview

A 240mm multiport radiator built for custom water-cooling loops. Its 44mm copper core and low-restriction design suit builds that prioritize quiet operation and flexible tubing routes.

Core Design and Materials

The radiator uses sixteen 2mm copper tubes and high-grade non-louvered copper fins at 18 FPI density. This construction balances thermal transfer with minimal air resistance, allowing effective cooling at low fan speeds. The core is pressure tested to 1 bar.

Port Layout and Loop Integration

Four G1/4 ports sit on one end tank and a fifth on the opposite end for draining and bleeding. Modular plugs and adapters in the aluminum end caps can be rearranged to suit tube routing. Low flow restriction lets a single D5 or DDC pump drive multiple radiators.

Mounting and Compatibility

Black M4 Philips screws are included for six 120mm fans of standard 25mm thickness. EK recommends fans with sealed-edge frames for optimal performance in push or pull configurations. The unit measures 285mm long, 130mm wide, and 44mm high.

Modular Construction and Ecosystem

Stainless steel side plates with semi-gloss black paint and matte black fins attach to extruded aluminum end caps with a contrasting silver finish. The design allows easy disassembly for painting or modification. EK-Matrix7 standardization aligns port spacing with Reflection² distro plates for clean parallel tubing runs.
