Radiator EKWB model — brass/copper/stainless steel white 130×285×58 mm

EKWB radiator model 3831109839492 is a 58 mm–thick EK-Quantum Surface X series radiator finished in white. Constructed from brass, copper and stainless steel, this compact radiator measures 130×285×58 mm and weighs 1.58 kg. It is intended as a replacement or upgrade component for custom PC liquid-cooling loops and provides a metal-core heat-exchange surface suitable for CPU and GPU water-cooling setups in desktop systems. The X series core uses sixteen 2 mm copper tubes and high-grade non-louvered copper fins with an 18 FPI density to balance thermal transfer and air resistance.

Advantages

The 58 mm thickness increases heat capacity compared with thinner radiators and is designed to benefit from medium and high-speed fans or push/pull configurations. Four G1/4" threaded connection ports on the body plus a fifth G1/4" port on the end tank enable flexible loop routing and straightforward draining or air bleeding. The radiator is engineered for low coolant-flow restriction to reduce pump load and allow multiple radiators on a single pump. Durable materials and a semi-matte white coating on the stainless-steel side plates combine with extruded aluminum end caps for mechanical rigidity and a premium fit and finish.

Suitable for

• Custom desktop water-cooling loops for CPU cooling
• GPU water blocks in combined CPU/GPU loops
• High-performance or overclocked systems requiring increased radiator volume
• Cases that can accommodate 58 mm thick radiators and 120 mm fan mounting

How to use

Install the radiator into your case using the supplied M4 screws for fan mounting and case attachment; use the eight M4x30 mm screws for 25 mm thick 120 mm fans and the M4x5 mm screws for securing the radiator to the chassis. Configure tubing using the G1/4" ports to suit your loop layout, reserving the end-tank G1/4" port for draining and air bleeding. Follow standard loop-filling procedures, purge air thoroughly and confirm pump flow before normal operation. When using thicker radiators like this X series model, choose fans with sufficient airflow to move heat through the 58 mm core—medium to high-speed fans or push/pull setups are appropriate.

Recommendations

Use fans rated for medium to high airflow and consider push/pull configurations to maximize thermal performance. Prefer sealed-edge frame fans for consistent airflow across the square fan casing. Use the included M4 screws to avoid damaging the radiator; if longer screws are needed, ensure they do not reach internal areas beyond the fins. For loop planning, leverage the multiple G1/4" ports to create clean tube runs and use the dedicated end-port for draining and bleeding air.
