## Long description

The EK-Quantum Surface S360 radiator is a 360mm liquid-cooling radiator designed for custom desktop PC loops and compact builds where space is limited. Constructed from a combination of aluminium, brass, copper and stainless steel with a full black finish, this 405×130×30 mm radiator supports standard 120 mm fan mounting and weighs approximately 0.95 kg. The Surface S series uses 16 copper tubes and non-louvered copper fins with 20 FPI density to balance thermal transfer and airflow resistance, delivering efficient cooling at low to medium fan speeds.
Advantages
The slim 30 mm thickness makes this radiator suitable for tight case layouts while maintaining strong thermal performance compared with previous generations. The improved fin structure and optimized core provide up to 20% better core-to-core performance versus its predecessor. The all-black finish covers frame, end caps, port adapters, fins and screws for a consistent stealth appearance. Low flow restriction in the core design minimizes pump load, enabling use of single-pump configurations and multiple radiators in the same loop.
Suitable for
Custom PC water-cooling loops in mid-tower and compact cases
Upgrading or replacing an existing 120 mm fan-based radiator
Systems requiring low-noise cooling at low to medium fan speeds
DIY modding and visual customization in black-themed builds
Key specifications

How to use
Mount the radiator to your case or radiator bracket using the supplied M4 screws and 120 mm fans of standard 30 mm thickness. Connect inlet and outlet ports to your loop using appropriate fittings and tubing, observing correct orientation for flow. Use the radiator in a push or pull fan arrangement as space and airflow allow; EK notes that push/pull configurations on this slim Surface radiator do not provide proportional gains, and adding an additional radiator is preferable if more cooling capacity is required. Ensure the loop is properly bled and leak-tested before powering the system.
Usage recommendations
For optimal balance of noise and cooling, use high-quality 120 mm fans with sealed-edge frames and operate them at low to medium speeds. Prefer EK-compatible fittings and follow Matrix7 spacing if integrating multiple EK components to achieve clean and parallel tubing runs. When installing fans, use the supplied screws; if longer screws are required, verify they will not damage structural elements beyond the fins. If additional cooling is needed, add another radiator rather than relying solely on push/pull on this slim model.
