The EK-Quantum Surface S radiator (MPN 3831109838952) is a compact, 30 mm thick liquid-cooling radiator designed for space-constrained PC cases. Constructed from brass, copper and stainless steel with a white semi-matte finish on the side plates and a black matte coating on the fins, it features 16 copper 2 mm-wide tubes and a high-grade non-louvered fin structure at 20 FPI to balance thermal transfer and air resistance. The radiator uses extruded aluminum end caps and is compatible with standard 120 mm, 25 mm-thick fans supplied with M4 Philips round-headed screws. It is EK-Matrix7 compatible for standardized port positioning and can be installed in multi-radiator loops with typical D5 or DDC pumps thanks to its low flow restriction.

Advantages

The Surface S radiator offers improved core performance — up to 20% better than the previous CoolStream SE core — through an optimized fin structure and radiator core. Its thin 30 mm profile provides strong cooling at low and medium fan speeds while remaining suitable for tight case layouts. The design minimizes coolant flow restriction, supports clean parallel tubing runs with Matrix7 compatibility, and uses durable materials and standardized M4 screws for straightforward installation and safe use even if longer screws are sourced. The modular construction enables easy disassembly for DIY modding or custom finishing.

Suitable for

• Compact and mid-tower PC builds where radiator thickness is limited
• Custom water-cooling loops using a single D5 or DDC pump
• Setups requiring low-to-medium fan speeds to reduce noise
• Systems aiming for clean, parallel tubing runs using EK-Matrix7 components
• DIY case modding and radiator customization

How to use

Mount the radiator in a location that supports a 30 mm-thick 120 mm radiator using the supplied M4 screws and standard 120 mm fans (25 mm thickness). Connect the radiator ports according to EK-Matrix7 alignment when integrating with other EK components for neat tubing runs. Use a single D5 or DDC pump for multi-radiator loops, as the radiator’s low flow restriction helps maintain adequate coolant circulation. Avoid push/pull fan configurations expecting proportional gains; instead, add another radiator if more cooling capacity is required.

Recommendations

Use sealed-edge-frame fans (such as EK fans or similar) for optimal airflow and minimal hydraulic losses. When replacing screws, prefer M4 screws; longer screws will contact fins but are allowed without compromising the core’s structural integrity. For best thermal results, pair the radiator with low-to-medium fan speeds and consider additional radiators rather than push/pull setups for higher cooling demands.
