Overview

A slim 280mm copper radiator built for space-constrained custom loops. It delivers strong thermal performance at low fan speeds and fits standard 140mm fans.

Design and Build

The radiator measures 325mm long, 45mm wide, and 30mm thick, weighing 0.85kg. Thick extruded aluminum end caps with a silver finish join white semi-matte stainless steel side plates. Fins carry a black matte coating with high thermal conductivity. Included black M4 Philips screws mount standard 25mm thick 140mm fans.

Thermal Performance

Eighteen 2mm copper tubes and 20 FPI non-louvered fins balance heat transfer and air resistance. The core performs up to 20 percent better than the previous CoolStream SE generation. Low restriction allows multiple radiators on a single D5 or DDC pump without added stress.

Modular Construction

A modular design makes disassembly straightforward for painting or modification. Longer M4 screws can be sourced if needed; the core tolerates accidental over-insertion by contacting only the fins. EK recommends using only the supplied screws for standard installations.

EK-Matrix7 Integration

Matrix7 standardizes port positions and spacing across Quantum components. This radiator aligns with Reflection² distro plates and allows swapping between S, P, and X series Surface radiators in the same mount when case clearance permits.
