Overview

A 58mm thick 360mm copper radiator designed for custom water cooling loops. It suits builders who need high heat dissipation using medium or high-speed fans.

Design and Construction

The radiator features a copper core with sixteen 2mm tubes and high-grade non-louvered fins. Stainless steel side plates have a semi-gloss black coating, while the fins use a black matte finish. Extruded aluminum end caps with a silver accent cover the internals and create a rigid structure.

Performance and Use

The thick X Series core requires medium to high-speed fans or push-pull configurations for optimal heat removal. Low flow restriction allows multiple radiators on a single D5 or DDC pump. Low airflow restriction keeps case ventilation efficient for other components.

Features and Connectivity

Five G1/4 threaded ports provide flexible loop planning, with a dedicated end-tank port for draining and bleeding. Modular plugs in the end caps let users reconfigure port positions. The unit is EK-Matrix7 compatible for seamless integration with Reflection² distro plates and other Quantum components.

What Is Included

Black M4 Philips round-head screws are supplied for mounting three 120mm fans with standard 25mm thickness. EK recommends fans with sealed-edge frames for best results. The radiator is pressure tested up to 1 bar.
