## Long description

The EK-Quantum Surface X series radiator is a thick 58 mm PC liquid-cooling radiator designed for high cooling capacity in custom water-cooling loops. Constructed from brass, copper and stainless-steel components with a black finish and contrasting silver extruded aluminum end caps, this radiator measures 525×130×58 mm and features sixteen 2 mm copper tubes and non-louvered copper fins at 18 FPI for balanced thermal transfer and airflow. The unit includes five G1/4" threaded ports (four on the body and one on the end-tank) to simplify tube routing, draining and air bleeding, and is compatible with standard 120 mm, 25 mm-thick fans using the supplied M4 screws.
Advantages
The 58 mm thick X series provides increased cooling capacity compared with thinner radiators and benefits most from medium to high-speed fans or push/pull configurations. Low internal flow restriction protects pump performance and allows multiple radiators on a single pump. The radiator’s modular multiport design offers flexible tube routing, while durable materials and a rigid construction with stainless-steel side plates and coated fins ensure longevity and consistent thermal behaviour. Supplied M4 screws and Matrix7 compatibility simplify installation and integration with other EK Quantum components.
Suitable for
High-performance gaming PCs and overclocked systems requiring strong heat dissipation
Workstation rigs with heavy CPU/GPU thermal loads
Custom water-cooling builds using multiple radiators or single-pump setups (D5 or DDC)
DIY modding projects where easy disassembly and aesthetic continuity are required
Key specifications
Dimensions: 525 × 130 × 58 mm
Materials: brass, copper tubes, stainless-steel side plates, extruded aluminum end caps
Tubes: 16 copper tubes, 2 mm width
Fins: non-louvered copper fins, 18 FPI
Ports: five G1/4" threaded ports (four on body, one on end-tank)
Fan compatibility: 120 mm fans, 25 mm thickness (screws included)
Included fasteners: 16 × M4×30 mm screws for fans, 16 × M4×5 mm screws for case mounting, 6 mm and 9 mm steel Allen keys
How to use
Mount the radiator in your case using the supplied M4 screws and attach compatible 120 mm fans (25 mm thickness) in a push, pull, or push/pull configuration depending on noise and performance needs. Configure tube routing using the interchangeable G1/4" ports and use the dedicated end-tank port for draining and air bleeding. Ensure the loop is filled and bled according to standard custom-loop procedures and use an appropriate pump (for example D5 or DDC) to maintain sufficient coolant flow. Avoid slow-running low-airflow fans on this 58 mm core as they cannot provide adequate airflow for optimal heat removal.
Usage recommendations
Use medium to high-speed fans or a push/pull setup for best thermal performance, keep fan frames sealed-edge or similar to avoid hydraulic losses, and prefer EK or equivalent fans. Use only included M4 screws for typical installations; longer M4 screws may be used if needed but can contact the fins without damaging the radiator core. Follow Matrix7 alignment when integrating other EK Quantum components for consistent tube routing and aesthetics.
