Overview

A white 280mm radiator built for custom water-cooling loops. It fits six 140mm fans and offers five G1/4 ports for flexible routing.

Core Design and Materials

The radiator uses a copper fin and channel core measuring 44mm thick. Eighteen 2mm copper tubes run the full length for unrestricted coolant flow. Non-louvered fins at 18 FPI balance heat transfer with low air resistance. Stainless steel side plates carry a durable semi-matte white coating, while fins receive a black matte finish with high thermal conductivity.

Port Layout and Loop Integration

Five G1/4 threaded ports are provided: four on the primary end tank and one on the opposite end for draining and bleeding. Modular plugs in the aluminum end caps can be rearranged to suit tube routing. The low-restriction internal design adds minimal pressure drop, allowing multiple radiators on a single D5 or DDC pump.

Fan Compatibility and Mounting

Six 140mm fan positions use standard M4 threads. Included black M4 Philips screws secure 25mm thick fans; longer M4 screws can be sourced if needed without damaging the core. Push, pull, or push-pull setups are all supported. EK recommends fans with sealed-edge frames for best results.

Modular Construction and Matrix7

The Surface series uses a modular architecture that simplifies disassembly for painting or modification. EK-Matrix7 standardizes dimensions and port spacing, enabling direct swaps between S, P, and X series radiators and clean parallel tubing runs with Reflection² distro plates.
