## Summary description

The EK Water Blocks 3831109839225 radiator is designed for efficient cooling in computer systems. Made from brass, copper, and stainless steel, it ensures durability and optimal heat dissipation. With dimensions of 130mm width, 420mm depth, and 44mm height, it fits various setups, providing reliable performance for high-demand applications.

## Long description

The EK-Quantum Surface P Series X-Flow radiator is a 44 mm thick liquid-cooling radiator designed for PC custom loops. Constructed from brass, copper and stainless-steel side plates with extruded aluminum end caps, the radiator uses sixteen 2 mm copper tubes and non-louvered copper fins with an 18 FPI density to provide efficient heat transfer while keeping airflow resistance low. The unit features eight G1/4" threaded ports (four on each end) that enable multiple crossflow tube-routing configurations and compatibility with standard 120 mm fans (25 mm thick) using the supplied screws.
Advantages
This Surface P radiator offers improved core performance compared with its predecessor, delivering up to 10% better thermal transfer due to an optimized fin structure and enhanced core design. The extruded aluminum end caps and semi-matte white stainless-steel side plates create a rigid, premium-feeling assembly while the black matte coated fins maintain high thermal conductivity. The modular multiport design allows sixteen different inlet/outlet configurations for flexible loop planning, and the low internal flow restriction supports multi-radiator loops with a single pump. The product is EK-Matrix7 compatible for consistent port spacing and cleaner parallel tubing runs.
Suitable for
Custom PC liquid-cooling loops requiring a 420 mm radiator
High-demand cooling setups that need low flow restriction
DIY modding and case-integrated radiator configurations

Ports: eight G1/4" threaded connection ports (four per end) supporting crossflow routing
Fan compatibility: standard 120 mm fans, 25 mm thickness
Weight: approximately 1.64 kg
How to use
Install the radiator in a compatible case location that supports 420 mm radiators and attach standard 120 mm fans in a push, pull, or push/pull configuration depending on desired airflow and noise. Configure inlet and outlet tubing using the G1/4" ports and supplied modular plugs/adapters to achieve preferred crossflow routing. Use the included M4 screws for fan and case mounting; if longer M4 screws are required, use caution as longer screws will contact the fins but are not intended to reach internal components. Ensure proper sealing of all threaded fittings and test the loop for leaks before powering the system.
Usage recommendations
For optimal results, pair this radiator with a pump capable of supporting multiple radiators (for example, D5 or DDC class pumps) and use fans with sealed-edge frames. Maintaining moderate fan speeds takes advantage of the low airflow resistance and helps keep system noise and case ventilation balanced.
