## Long description

The EK-Quantum Surface P Series X-Flow radiator (3831109838426) is a 420×130×44 mm high-performance PC liquid-cooling radiator constructed from brass, copper and stainless steel with a black finish. It features eight G1/4" threaded ports (four on each end) for flexible crossflow tube routing, sixteen 2 mm copper tubes and non-louvered copper fins at 18 FPI to balance thermal transfer and air resistance. The radiator’s extruded aluminum end caps, stainless-steel side plates and matte-coated fins form a rigid, premium enclosure compatible with standard 120 mm fans (25 mm thickness) using the supplied M4 screws.
Advantages
The Surface P core delivers up to 10% better thermal performance compared to the predecessor CoolStream PE due to an improved fin structure and optimized core design. Low flow restriction across the core minimizes pump load, enabling multiple radiators on a single D5 or DDC pump and allowing effective operation at lower fan speeds. Modular G1/4" ports and EK-Matrix7 compatibility simplify neat tube routing and integration with other EK Quantum components, while a modular assembly design makes disassembly, modding and replacement of covers straightforward.
Suitable for
Custom water-cooling loops requiring high thermal performance and low flow restriction
Systems using multiple radiators driven by a single pump (D5 or DDC)
PC builds needing flexible crossflow tube routing and clean parallel tube runs (EK-Matrix7 compatible)
Modding projects where easy disassembly and painting or cover replacement are desired

How to use
Install the radiator in your case using the supplied M4 screws, fitting 120 mm, 25 mm-thick fans in push, pull, or push/pull configurations as preferred. Configure tube routing using any combination of the four G1/4" ports on each end to achieve the desired crossflow layout. Connect the radiator into your loop keeping inlet and outlet orientation consistent with your pump and other radiators. When mounting fans, use the supplied M4×30 mm screws; longer M4 screws can be used if necessary but may contact the fins. Follow normal leak-testing procedures after assembly before powering the system.
Usage recommendations
Use sealed-edge framed 120 mm fans (EK or similar) for optimal airflow and minimal hydraulic losses; consider push/pull for maximum cooling. Prefer the supplied M4 screws for fan mounting and use low-restriction loop planning (EK-Matrix7 alignment) to maintain pump efficiency and tidy tubing runs.
