Overview

This 360mm all-black radiator uses a 44mm thick copper core with 18 FPI fins and two G1/4 ports. It suits custom loop builders who want low noise and high thermal performance.

Core Design and Materials

The radiator measures 405mm wide, 130mm deep, and 44mm thick with a weight of 1.6kg. Sixteen 2mm copper tubes run the full length, paired with high-grade non-louvered copper fins at 18 FPI. Every visible component, including the frame, end caps, port adapters, fins, and supplied M4 screws, features a black finish.

Performance Characteristics

The updated core delivers up to 10 percent better thermal performance than the previous CoolStream PE generation. Low coolant flow restriction allows multiple radiators on a single D5 or DDC pump. Low airflow restriction enables effective cooling at reduced fan speeds and keeps case ventilation balanced.

Fan Compatibility and Mounting

The unit supports up to nine 120mm fans using standard M4 threads. Included black M4 Philips screws are sized for 25mm thick fans; longer M4 screws can be used safely as they contact only the fins. EK recommends fans with sealed-edge frames for optimal push or pull operation.

Modular Construction and Ecosystem

The modular design simplifies disassembly for painting or custom modification. EK-Matrix7 standardization aligns port positions and spacing across compatible components for cleaner parallel tubing runs. The radiator is pressure tested to 1 bar and uses a multipass flow design.
