## Summary description

EKWB 3831109838693 radiator for PC liquid cooling loops, constructed from brass and copper with a black finish. Dimensions are 130 mm (width) × 285 mm (depth) × 58 mm (height) and weight 1.58 kg. Designed as a cooling system component for dissipating heat from coolant in custom water-cooling setups; suitable for CPU/GPU loop integration and compact builds.

## Long description

The EKWB 3831109838693 radiator is a 58 mm-thick EK-Quantum Surface X series component for custom PC liquid cooling loops. Constructed from brass and copper with a black finish, this compact 130 × 285 × 58 mm radiator weighs 1.58 kg and is designed to dissipate heat from coolant in CPU and GPU loops. Its rigid construction, extruded aluminum end caps and stainless-steel side plates ensure mechanical strength and a consistent appearance, while sixteen 2 mm copper tubes and high-grade non-louvered copper fins with an 18 FPI density optimise coolant flow and thermal transfer.
Advantages
The 58 mm core thickness increases thermal capacity compared with thinner radiators and benefits from medium to high-speed fans or push/pull configurations. Four standard G1/4" threaded ports on the main body plus a fifth G1/4" port on the end-tank provide versatile connection and make draining and air bleeding straightforward. Low internal flow restriction reduces pump load and allows multiple radiators on a single pump. Supplied M4 screws and standardized mounting minimise installation friction, while the matte black fin coating and semi-gloss painted side plates balance thermal conductivity with a clean visual finish.
Suitable for
Compact custom water-cooling loops where a 130 × 285 × 58 mm radiator fits
CPU and GPU cooling in single-loop or combined-loop configurations
Builds using medium or high-speed 120 mm fans and push/pull setups
DIY modding and cases that benefit from EK-Matrix7 dimensional compatibility

How to use
Mount the radiator in your case where a 120 mm fan pack can be installed; use the supplied M4x30 mm screws for 25 mm thick fans and M4x5 mm screws for case mounting. Configure fan orientation for push, pull or push/pull according to your airflow plan and install medium to high-speed fans for best results with the 58 mm core. Use the G1/4" ports to connect tubing and plan tubing runs to utilise the additional side ports and the end-tank bleed/drain port for filling and maintenance. Follow standard loop-building safety and leak-testing procedures before powering the system.
Usage recommendations
EK recommends pairing this 58 mm X series radiator with medium or high-speed 120 mm fans or a push/pull configuration; slow-running fans are not advised for optimal thermal performance. Use the supplied screws where possible and take advantage of the extra G1/4" port for easy draining and air bleeding during maintenance.
