## Summary description

Radiator by EK Water Blocks (model 3831109839218) for computer liquid cooling systems. Constructed from brass, copper and stainless steel with a white finish.

Designed to dissipate heat from coolant loops in PCs and custom water-cooling setups; suitable for mounting in cases or external cooling mounts.

## Long description

The EK-Quantum Surface P-series radiator in white is a 405×130×44 mm cooling component for custom PC liquid cooling loops. Constructed from brass, copper and stainless steel, it features a 44 mm thick core with sixteen 2 mm copper tubes and high-grade non-louvered copper fins at 18 FPI. The radiator offers low flow restriction, five G1/4" threaded ports (four on the body and one on the end tank) for flexible loop routing and draining, and extruded aluminum end caps with stainless-steel side plates finished in semi-matte white. It is compatible with standard 120 mm, 25 mm-thickness fans in push, pull, or push/pull configurations and includes mounting screws and hex keys for installation.
Advantages
The radiator combines improved core design and optimized fin structure to deliver up to 10% better thermal performance compared to the previous generation, while maintaining low coolant flow restriction. Its 18 FPI fin density and non-louvered fins balance thermal transfer and air resistance, enabling effective cooling even at low fan speeds. The multiport layout and five G1/4" ports make loop planning and draining simpler, and its modular construction allows straightforward disassembly for maintenance or modification. Durable materials and a semi-matte white finish provide mechanical rigidity and a consistent aesthetic in white-themed builds.
Suitable for
Custom PC liquid cooling loops in mid-tower and full-tower cases
External or case-mounted radiators where a 405×130×44 mm form factor is required
Systems requiring low flow restriction to run multiple radiators on a single pump
Builds that use 120 mm fans in push, pull or push/pull configurations
Key specifications
External dimensions: 405 mm × 130 mm × 44 mm (length × width × thickness)
Construction materials: brass, copper (tubes and fins), stainless-steel side plates, extruded aluminum end caps
Core: sixteen 2 mm copper tubes across the radiator length
Fin density: 18 fins per inch (FPI), non-louvered copper fins with matte coating
Ports: five G1/4" threaded connection ports (four on the body, one on the end tank for draining/bleeding)
Fan compatibility: standard 120 mm fans, 25 mm thickness; supports push, pull and push/pull setups
Mounting hardware: supplied M4 Phillips screws for fan and case mounting; includes hex keys
How to use
Mount the radiator to your case or external bracket using the supplied M4 screws, matching the 120 mm fan hole pattern. Use appropriate-length M4 screws for fan thickness and case mounting; the supplied screws are recommended to avoid contact with the fins. Connect tubing to the G1/4" ports according to your loop design, using the extra side ports or the end-tank port to simplify routing and for draining or bleeding air. Install fans in push, pull or push/pull orientation depending on available space and desired performance, and ensure secure, leak-free fittings before filling the loop. After assembly, perform a leak test and bleed the system through the end-tank port to remove trapped air for optimal flow.
Usage recommendations
Use low-speed, sealed-frame 120 mm fans to maintain a balance between noise and thermal performance; consider push/pull on this 44 mm radiator for maximum cooling. To minimize flow restriction and maintain pump longevity, pair with a compatible D5 or DDC-class pump when running multiple radiators. When modding or painting, follow safe disassembly practices and protect the internal fins and tubes from damage.
