## Summary description

The EK Water Blocks 3831109839751 radiator is designed for efficient cooling in computer systems. Made from brass, copper, and stainless steel, it features a sleek white finish. Dimensions are 130 mm width, 165 mm depth, and 30 mm height, making it a compact choice for various builds.

## Long description

The EK-Quantum Surface S radiator is a compact, high-performance liquid-cooling radiator with a thickness of 30 mm, engineered for space-constrained PC cases. Constructed from brass, copper and stainless steel with a white finish and reinforced extruded aluminum end caps, it features 16 copper tubes (2 mm wide) and high-grade non-louvered copper fins at 20 FPI for balanced thermal transfer and low air resistance. The radiator is compatible with standard 120 mm fans of 25 mm thickness and includes M4 mounting screws.
Advantages
Despite its reduced 30 mm thickness, the Surface S delivers strong thermal performance at low and medium fan speeds thanks to an optimized core and enhanced fin structure that provides up to 20% better core-to-core performance compared with its predecessor. The modular construction, rigid stamped side plates and durable semi-gloss black side coating combine with a matte black high-conductivity fin coating to provide a durable and serviceable product. Low internal flow restriction means this radiator places minimal stress on the loop and allows multiple radiators to be used with a single D5 or DDC pump.
Suitable for
 Compact PC builds with limited radiator clearance
 Custom water-cooling loops requiring low flow restriction
 Systems using standard 120 mm fans (25 mm thickness)
 Modding projects where easy disassembly and painting are desired

How to use
Mount the radiator in a compatible location within your case that supports a 30 mm thick radiator and standard 120 mm fans. Use the supplied M4x30 mm screws to attach 25 mm thick 120 mm fans to the radiator; use the M4x5 mm screws to secure the radiator to the case. Connect the radiator into your custom water loop using appropriate fittings and tubing; the internal low-restriction core is designed to work with typical single-pump setups such as D5 or DDC. Avoid using a push/pull fan configuration expecting proportional performance gains; instead consider adding additional radiators if more cooling capacity is required.
Usage recommendations
Use sealed-edge or similarly rigid 120 mm fans for optimal airflow; when performing modifications or using non-standard screw lengths, prefer the supplied screws to avoid damage and, if longer screws are necessary, note that they will contact the fins rather than critical structural components. For clean tubing runs and easy system upgrades, pair the radiator with EK-Matrix7-compatible components such as Reflection² distro plates.
