## Long description

The EK Water Blocks 3831109839225 Brass Copper Stainless Steel White is a 420×130×44 mm PC liquid-cooling radiator from the EK-Quantum Surface P Series X-Flow family. Constructed with brass, copper tubes and stainless-steel side plates, this radiator uses a 44 mm thick core with sixteen 2 mm copper tubes and high-grade non-louvered copper fins at 18 FPI to provide efficient heat transfer while maintaining low airflow resistance. The radiator includes eight G1/4" threaded ports (four on each end) for flexible crossflow tube routing and is finished with extruded aluminum end caps and a durable semi-matte white coating on the side plates for a consistent aesthetic in white builds.
Advantages
The X-Flow core design offers multiple connection options without compromising thermal performance, enabling up to sixteen different in/out routing configurations. The upgraded Surface P core yields improved thermal transfer and optimized fin structure that delivers up to 10% better performance compared to the previous generation. Low internal flow restriction minimizes pump load, while the 18 FPI fin density and 2 mm copper tubes balance cooling efficiency with low fan-speed operation. Supplied M4 screws and modular end-cap plugs simplify installation and future disassembly for modifications.
Suitable for
Custom PC liquid-cooling loops requiring a 420 mm radiator with 44 mm thickness
Builds that need multiple tube routing options or crossflow configurations
Silent or low-RPM fan setups that require low airflow resistance
White-themed PC builds seeking a color-matched radiator finish
DIY modding and case integrators who may disassemble or paint the radiator
Key specifications
Dimensions: 420 mm (length) × 130 mm (width) × 44 mm (thickness)
Core layout: X-Flow multiport with four G1/4" ports per end (eight usable ports)
Tubes: sixteen copper tubes, 2 mm width each
Fin density: 18 fins per inch (FPI), non-louvered copper fins with black matte coating
End caps: extruded aluminum with contrasting silver finish
Side plates: stainless steel with semi-matte white paint
Fan compatibility: 120 mm fans, 25 mm thickness (screws for mounting included)
Included fasteners: M4 Philips round-headed screws for fan and case mounting; supplied hex keys
How to use
Mount the radiator in a 120 mm fan-compatible position using the supplied M4 screws for either push, pull or push/pull configurations with standard 25 mm fans. Choose the desired inlet and outlet ports on the X-Flow ends, using the modular plugs and adapters to configure tubing routes for optimal loop layout. Tighten fittings to the G1/4" ports while taking care not to over-torque; the core is designed to prevent structural damage even if longer screws contact the fins. For low pump strain, pair the radiator with standard D5 or DDC pumps and ensure correct flow direction through the loop.
Usage recommendations
Use fans with sealed-edge frames and consider push/pull fan arrangements to maximize cooling potential. When assembling the loop, prefer the supplied M4 screws to avoid accidental damage; if longer screws are required for mounting, verify clearance to avoid contact with the fin stack. For multi-radiator loops, use low-restriction routing and a suitable single pump to maintain adequate flow. The radiator's white finish is intended to match common white PC cases—test paint or mods on a spare part if planning custom finishes.
