Overview

A 360mm crossflow radiator built for custom liquid cooling loops. It offers eight G1/4 ports for flexible tubing routes and a low-restriction core.

Core Design and Materials

The radiator uses a copper core with sixteen 2mm tubes and high-grade non-louvered fins at 18 FPI. This structure balances thermal transfer and air resistance for strong performance at low fan speeds. End caps are thick extruded aluminum with a silver accent, while stainless steel side plates feature a semi-gloss black coating.

Crossflow Port Flexibility

Four G1/4 ports on each end provide sixteen possible inlet and outlet combinations. Modular plugs and adapters in the end caps let you configure tube routing without compromising flow. The low-restriction design adds minimal stress to the loop pump.

Fan and Mounting Support

Supports six 120mm fans in push, pull, or push-pull configurations. Standard M4 threads secure fans up to 25mm thick using the included black Philips screws. EK recommends fans with sealed-edge frames for best results.

Modular Construction and Integration

The modular design allows easy disassembly for painting or modification. EK-Matrix7 compatibility aligns port positions and dimensions with other Quantum components like Reflection² distro plates, enabling clean parallel tubing runs and simple upgrades between Surface series radiators.
