## Summary description

The EK Water Blocks EK-Quantum Surface S360 is a high-performance heatsink/radiator designed for efficient cooling. With dimensions of 405mm width, 130mm depth, and 30mm height, it fits various computer cases. Its sleek black design complements modern builds while ensuring optimal thermal management for your components.

## Long description

The EK Water Blocks EK-Quantum Surface S360 Black 405mm is a high-performance, slim-profile heatsink/radiator engineered for liquid-cooled PC systems where space is limited. With overall dimensions of 405mm width, 130mm depth and a thickness of only 30mm, the S360 offers a compact footprint while maintaining effective thermal management. Its construction includes 16 copper 2mm tubes, high-grade non-louvered copper fins with 20 FPI density, extruded aluminum end caps and coated stainless-steel side plates for a durable black finish. The radiator is compatible with standard 120mm fans of 25mm thickness and is designed to minimise coolant flow restriction, allowing efficient operation with common D5 or DDC pumps and enabling multi-radiator loops without placing undue stress on the pump.
Advantages
The slim 30mm thickness makes the Surface S360 suitable for compact or space-constrained cases while delivering strong thermal performance at low and medium fan speeds. The updated core and enhanced fin structure improve heat transfer efficiency compared to previous generations, with up to 20% better core-to-core performance over the predecessor. Low internal flow restriction and 16 copper tubes ensure steady coolant circulation, and the semi-gloss black coating combined with matte-coated fins and silver-finish end caps provide a robust, premium appearance. Supplied M4 Philips round-headed screws simplify mounting and standardisation allows sourcing of alternative screws if longer fasteners are required.
Suitable for
Compact or mid-tower PC builds with limited radiator clearance
Custom liquid cooling loops requiring low flow restriction
Multi-radiator setups using a single D5 or DDC pump
Users who prefer low- to medium-speed fan operation for quieter cooling
Modders seeking easy disassembly and compatibility with standardized mounting systems
Key specifications
Overall dimensions: 405 mm (width) × 130 mm (depth) × 30 mm (thickness)
Tube material and count: copper, 16 tubes, 2 mm width each
Fin type and density: non-louvered copper fins, 20 FPI
End caps: extruded aluminum with contrasting silver finish
Side plates: stainless steel with semi-gloss black coating
Fan compatibility: fits standard 120 mm fans with 25 mm thickness
Airflow characteristics: low airflow restriction optimized for low/medium fan speeds
Flow restriction: low internal coolant flow resistance suitable for single-pump loops
How to use
Mount the EK-Quantum Surface S360 in the case position that provides adequate clearance for a 30 mm-thick radiator and 25 mm-thick fans. Use the supplied M4 Philips round-headed screws to attach 120 mm fans or to secure the radiator to the case. Connect the inlet and outlet ports to your loop using appropriate fittings and tubing, ensuring secure, leak-free connections. When integrating multiple radiators, plan loop routing and pump capacity (D5 or DDC recommended) to maintain proper flow. Avoid using a push/pull fan configuration expecting proportional gains; if additional cooling is required, add another radiator to the loop rather than relying on push/pull on this slim core.
Usage recommendations
For optimal quiet operation and long-term reliability, pair the Surface S360 with low- to medium-speed sealed-edge fans and a compatible D5 or DDC pump. Use the included M4 screws for mounting where possible, and follow EK’s Matrix7 spacing for neat tube runs and easy integration with other EK Quantum components.
