## Summary description

EK Water Blocks radiator model 3831109839737 is a computer cooling system component made of brass, copper and stainless steel with a white finish.

Designed for liquid cooling loops, it provides heat dissipation for CPUs/GPUs and is suitable for custom water-cooling builds and system upgrades.

## Long description

EK Water Blocks 3831109839737 is a 58 mm thick EK-Quantum Surface X series radiator with a white semi-matte finish on stainless-steel side plates, contrasting silver extruded aluminum end caps and black matte coated fins. Constructed from brass, copper and stainless steel, it measures 145×605×58 mm and is designed for custom liquid-cooling loops. The radiator features eighteen 2 mm copper tubes and 18 FPI non-louvered copper fins to balance thermal transfer and air resistance, plus a multiport layout with four G1/4" threaded connection ports and a fifth G1/4" port on the end-tank for draining and air bleeding.
Advantages
The thick 58 mm core provides improved heat dissipation when paired with medium to high-speed fans or a push/pull configuration, while low internal flow restriction reduces stress on pumps and enables multiple radiators to run from a single pump. The modular multiport design gives flexibility for loop planning and easier tube routing. Supplied M4 screws and compatibility with standard 140 mm, 25 mm-thickness fans simplify installation. Durable construction with extruded aluminum end caps and reinforced side plates enhances mechanical rigidity and allows for straightforward disassembly and DIY modification.
Suitable for
Custom PC liquid-cooling loops for CPUs and GPUs
High-performance systems requiring increased radiator surface and airflow
Multi-radiator loops where low pump load is important
Modding projects that require easy disassembly and painting

How to use
Mount the radiator in your case or external mounting location using the supplied M4 screws and ensure compatibility with 140 mm, 25 mm thickness fans. Configure the desired G1/4" port arrangement for inlet, outlet and drain ports to suit your loop routing; use the end-tank port for draining and air bleeding. Install medium to high-speed fans or a push/pull fan configuration to achieve optimal thermal performance with the 58 mm core. When integrating multiple radiators, verify pump capability (D5 or DDC recommended) and maintain proper tube routing to minimize unnecessary bends.
Usage recommendations
EK recommends using medium to high-speed or push/pull fan configurations with X Series radiators and avoiding slow-running fans, as adequate airflow is necessary to remove more heat than the thick core absorbs. Use only compatible M4 screws as supplied when possible, and take advantage of the modular design for easier maintenance, draining and custom modding.
