## Long description

The EKWB radiator 3831109839171 is a compact Surface P series radiator designed for custom PC liquid cooling loops. Constructed from brass, copper and stainless steel with a white semi-matte finish on the side plates and contrasting silver aluminum end caps, this 130 × 285 × 48 mm unit weighs approximately 1.21 kg. Its 48 mm thickness and 18 FPI high-grade non-louvered copper fins create an efficient balance of thermal transfer and low air resistance, while sixteen 2 mm copper tubes ensure unobstructed coolant flow across the full core length. The radiator features multiple G1/4" ports that increase routing flexibility and include a dedicated port for draining and air bleeding.
Advantages
The Surface P core offers improved thermal performance compared with its predecessor, delivering up to 10% better core-to-core cooling thanks to optimized fin geometry. Low flow restriction in the internal channeling reduces load on system pumps, allowing multiple radiators to be used on a single D5 or DDC pump. The radiator is compatible with standard 120 mm, 25 mm-thickness fans and supports push/pull configurations for higher cooling capacity. Durable construction with extruded aluminum end caps and coated stainless-steel side plates provides good mechanical rigidity and a finish tailored to popular white PC cases.
Suitable for
Custom PC water-cooling loops for CPU and GPU cooling
Compact or mid-tower builds requiring a 48 mm thick 120 mm-series radiator
Systems where low pump load and low-noise fan operation are priorities
DIY modding projects that need a paintable, modular radiator body
Key specifications
Dimensions: 130 × 285 × 48 mm
Weight: ~1.21 kg
Materials: brass, copper tubes, stainless-steel side plates, aluminum end caps
Core layout: sixteen 2 mm-wide copper tubes across the core
Fin density: 18 FPI (fins per inch), non-louvered copper fins with black matte coating
Porting: four side G1/4" threaded ports plus one G1/4" end-tank port for draining/air bleed
Fan compatibility: standard 120 mm fans with 25 mm thickness (supports push/pull)
Screw type supplied: M4 Philips round-headed screws
How to use
Install the radiator in your case at an appropriate mounting location for 120 mm fans using the supplied M4 screws. Configure G1/4" fittings and tubing according to your loop layout; the multiport design allows alternate inlet/outlet and drain/bleed positioning to simplify routing. Mount fans in either push, pull, or push/pull configuration depending on desired airflow and noise levels. When filling and commissioning the loop, use the dedicated end-tank G1/4" port to bleed air and drain the system as needed. Follow standard liquid-cooling procedures: leak testing, gradual power-up of pumps, and monitoring coolant flow and temperatures during first operation.
Usage recommendations
Use sealed-edge frame fans or EK-recommended fans at variable speeds to exploit the radiator's low airflow resistance; maintain proper loop flow by pairing with a D5 or DDC pump for multi-radiator setups. When modding or painting, disassemble following the modular design guidance and avoid overtightening screws—M4 screw compatibility provides margin for longer fasteners but sticking to the supplied screws is advised to prevent contact with fins.
