EK-Quantum Surface S360 - Black Edition is a 360 mm water radiator from EKWB, aimed at mid-range and high-end custom water cooling. With a thin 30 mm profile and a length of 405 mm, it is convenient for most mid-tower and full-tower cases, without requiring acrobatics during installation. The black coating helps to visually tie in with a typical “stealth” build, and the standard G1/4" thread gives you freedom in choosing fittings and tubes. If you are looking for a clean look and an organized water system with a 360 mm radiator, this model fits exactly into that role.

What you get is a thin aluminum radiator with a length of 405 mm and a width of 130 mm, which comfortably fits three 120 mm fans. The 30 mm thickness reduces the risk of conflict with the motherboard, RAM, or top elements in the case, especially when mounted in the top position. The aluminum construction keeps the weight lower and facilitates installation, which is a plus for lighter or compact chassis. The standard G1/4" thread guarantees compatibility with a huge range of fittings and water cooling components, so you can easily integrate it into an existing loop. With a 24-month warranty, you have peace of mind that the radiator is covered in case of manufacturing defects.

Thickness 30 mm, convenient for builds with limited space to the top panel or front radiator section.

Standard thread G1/4" for high compatibility with fittings, tubes, and the rest of the parts of the custom loop.

24 months warranty, providing security against defects related to manufacturing or material.

Who it is suitable for – if you are assembling a custom water cooling and you need a 360 mm radiator that fits without drama in a mid-tower or full-tower case, this model is a logical choice. It is suitable for gaming and enthusiast builds where you want balanced cooling and a clean external look. It is not suitable if you are looking for extremely thick radiators or solutions outside the standard 360 mm format.

The most sensible thing here is the combination of a thin 30 mm profile, standard G1/4" thread, and a classic black finish – a flexible enough solution for many different water configurations, without complicating the build.
