Overview

A slim 280mm copper radiator built for custom loops where space is tight. It delivers strong thermal performance at low fan speeds and integrates with EK-Matrix7 distro plates.

Design and Build

The radiator measures 325mm long, 145mm wide, and 30mm high, weighing 850g. Black stainless-steel side plates and matte black fins pair with silver extruded aluminum end caps for a rigid, premium structure.

Performance

Eighteen 2mm copper tubes and 20 FPI fin density deliver up to 20% better core performance than the previous CoolStream SE. Low flow restriction lets a single D5 or DDC pump drive multiple radiators.

Fan Compatibility

Supports two 140mm fans of standard 25mm thickness. EK recommends sealed-edge frames for optimal pull or push operation without hydraulic losses. Push-pull is not advised due to diminishing returns.

Connectivity and Extras

Two G1/4-inch ports accept standard fittings. The unit is pressure tested to 1 bar and fully EK-Matrix7 compatible, allowing direct swaps between S, P, and X series radiators. Eight M4x30mm screws are included.
