Overview

A 30mm slim 360mm copper radiator designed for space-constrained custom loops, offering strong thermal performance at low fan speeds and a white finish that matches popular cases.

Slim Design and Construction

The radiator measures 405mm long, 130mm wide, and only 30mm thick, weighing 0.95kg. Thick extruded aluminum end caps with a silver finish join white-coated stainless steel side plates. Copper fins carry a black matte coating for thermal conductivity, while the core uses 16 copper tubes across the full length.

Thermal Performance

Non-louvered copper fins at 20 FPI balance heat transfer and air resistance, delivering strong results at low and medium fan speeds. The multipass layout and low-restriction internals keep coolant flow restriction minimal, allowing multiple radiators on a single D5 or DDC pump.

Fan Compatibility and Mounting

Supports three 120mm fans with standard 25mm thickness using included black M4 Philips screws. EK recommends fans with sealed-edge frames for optimal pull or push performance without hydraulic losses. Push-pull configurations are not recommended for proportional gains.

Modularity and Ecosystem

EK-Matrix7 standardization aligns port positions and dimensions with Reflection² distro plates, enabling easy swaps between S, P, and X series radiators. The modular design simplifies disassembly for painting or modification, and M4 threads allow sourcing longer screws if needed.
