Fan module EKWB — white 12 V fan module for PC cooling

The EKWB 3831109898055 fan module in white is a 12 V replacement or upgrade fan component designed for PC cooling systems. Intended for integration into modular liquid cooling loops, radiator assemblies or chassis ventilation, this fan module manages airflow to support CPU, GPU and system thermal control. Supplied in a box and finished in a milky white shade that matches common white PC cases, the module combines a full-frame, high-static-pressure design with addressable D-RGB lighting and modern connector standards for simplified installation and cable management.

Advantages

The fan module uses a Full Pressure Technology (FPT) full-frame design to minimize air escape and maximize static pressure across radiators and dense fin stacks. A Fluid Dynamic Bearing (FDB) motor reduces operational friction and long-term noise increase while allowing reliable horizontal or vertical mounting. Integrated D-RGB LEDs are positioned in the rotor for even light dispersion without shortening blade length, and the white impeller and frame are color-matched to common white cases. The OmniLink-compatible daisy-chain connector simplifies wiring by consolidating PWM and D-RGB signals into a single Micro-fit 8-pin connection, reducing cable clutter and easing routing.

Suitable for

• High-performance liquid cooling radiators (140 mm)
• Chassis ventilation where matched white aesthetics are required
• Modular cooling builds requiring daisy-chained fan control and D-RGB synchronization
• Upgrades or replacements of existing 140 mm fan assemblies in CPU/GPU loops

Key specifications

• Fan size: 140 mm nominal
• Rated voltage: 12 V
• Frame design: Full Pressure Technology (full-frame, sealed contact to radiator)
• Bearing type: Fluid Dynamic Bearing (FDB) for low friction and extended service life
• Impeller: 7-blade milky-white design optimized for light dispersion and static pressure
• Lighting: addressable D-RGB LEDs located in the rotor (3-pin 5 V compatible)
• Connector ecosystem: EK-OmniLink daisy-chain capable using Micro-fit 8-pin interconnect
• Orientation: suitable for horizontal and vertical mounting

How to use

Install the fan module into a compatible 140 mm mounting position on a radiator or chassis using standard fan screws. Connect power and PWM control through the EK-OmniLink or the supplied connector to the corresponding fan hub or controller; for D-RGB lighting, connect the 3-pin 5 V D-RGB connector to an addressable ARGB header or compatible controller, aligning the arrow on the connector with the +5 V marking on the header. When daisy-chaining multiple fans, link Micro-fit 8-pin connectors in sequence to consolidate signal and power wiring, then connect the final cable to the controller or hub.

Recommendations

For best cooling performance, mount the fan to make direct contact with the radiator frame where possible to take advantage of the FPT sealing design. Use the EK-OmniLink daisy-chain to reduce cable clutter, and ensure the 3-pin D-RGB connector polarity aligns with the motherboard or controller header to avoid LED issues. Regularly inspect and clean the fan blades and radiator fins to maintain airflow and static pressure over time.
