DOCTOR METAL UF-SL120-3B 3×120mm ARGB case fan 800-1900 RPM 55-60 CFM 17-31 dB

Three-pack modular ARGB fans

The DOCTOR METAL UF-SL120-3B bundles three 120 mm fans that snap together using a proprietary interlocking frame. A single controller handles power and lighting for the entire chain, so only one cable runs to the motherboard or a supplied hub. The system is aimed at builders who want clean cable routing and synchronised lighting without managing individual fan headers.

Fluid bearing and daisy-chain mounting

Each fan uses a fluid circulative bearing rated for long service life at speeds between 800 and 1900 RPM. The modular frame lets adjacent units share screw holes, reducing the total fastener count when installing multiple fans side by side. ARGB illumination comes from 32 addressable LEDs per fan, including rear-facing emitters that keep light effects visible even when the fan is mounted in a push-pull configuration.

Quiet airflow with software control

At minimum speed the fans produce 17 dB while moving 55 CFM, rising to 31 dB and 60 CFM at the 1900 RPM ceiling. Static pressure peaks at 2.54 mm H₂O, suitable for radiator or restrictive mesh placements. Fan curves and lighting patterns are adjustable through L-Connect software or standard motherboard 5 V ARGB headers, with the controller supporting up to 16 fans across its ports.
