EK-Quantum Surface S360 - Black is a thin 360 mm radiator for water cooling, aimed at well-balanced custom loop systems where you seek serious cooling without losing space in the case. With a thickness of 30 mm and a length of 405 mm, it easily fits in most mid and full tower cases with support for 360 mm radiators. The combination of copper, aluminum, and brass in the construction provides good efficiency and durability. The black coating and clean design easily match most black-themed builds.

What you get is a 360 mm radiator with a focus on balance between airflow and surface area for heat dissipation. At FPI: 20 (fins per inch), the radiator is optimized for fans that can provide more meaningful static pressure – ideal if you already have quality 120 mm fans or plan to get some. The standard G1/4" thread gives you full freedom in choosing fittings and loop configuration. With a thickness of only 30 mm, the radiator is convenient for more compact cases or configurations with taller RAM/VRM coolers, where every millimeter of clearance matters.

Radiator with a length of 360 mm, suitable for three 120 mm fans and a good area for heat dissipation in gaming and workstation configurations.
Compact thickness of only 30 mm, which facilitates installation in tighter cases and reduces the risk of conflicts with motherboards and RAM.
Dimensions 405 x 130 x 30 mm, which give you a clear idea of whether it will fit for top or front mounting in your specific case.
Fine structure with FPI: 20, oriented towards fans with better static pressure for more effective cooling at higher RPMs.
Materials used copper, aluminum, and brass, ensuring good thermal conductivity and structural stability over time.
Standard threads G1/4", which guarantees compatibility with a wide range of fittings, quick connects, and other components in the loop.
Black color Black, which visually matches most builds and does not attract unnecessary attention if you are aiming for a cleaner look.
Warranty 24 months, for peace of mind during long-term operation of your custom water cooling.

This radiator is suitable if you want 360 mm cooling area in a custom loop system, but you do not have space or desire for thicker “brick” radiators. It is a good choice for gaming and creative configurations that aim for stable temperatures under load and relatively clean installation. If you plan extreme overclocking of multiple hot components and have a large chassis, you might want a thicker radiator or an additional radiator in the loop.

The most meaningful thing here is the combination of 360 mm format, 30 mm thickness, and 20 FPI – serious enough cooling in a compact format that you can actually fit into many different cases without drama.
