The Lian Li UNI FAN SL Wireless LCD 3-Pack in Black consists of three 120 mm case fans for PC cooling systems. These fans feature a built-in 1.6-inch IPS LCD display in the center with a resolution of 400 x 400 pixels, a peak brightness of 500 nits, and 24-bit sRGB color reproduction to display system information, images, animations, or video clips. Each fan measures 120 x 124.5 x 28 mm and operates at a maximum speed of 1900 RPM, generating an airflow of 58.08 CFM at a static pressure of 2.4 mmH2O, making them suitable for case ventilation or radiator use. The PBT material construction with FDB bearings, rubber vibration-damping pads, and stabilized fan blades ensures noise levels of 29.5 dBA during operation. The fans integrate 40 LEDs with dual-zone RGB lighting for customizable effects. Connectivity is wireless via proprietary daisy-chain technology using pogo pin connectors, allowing up to four fans to be connected without cables, with a single cable providing power for each cluster. Control is wireless through a built-in 2.4 GHz receiver in the fan connector, compatible with the L-Wireless USB controller and the L-Connect 3 software for adjusting fan speeds, RGB lighting, and LCD content. The system supports multiple clusters, with the controller managing up to seven channels for simultaneous control of 28 fans. The rated voltage is 12 V with an operating range of 5 V to 13.2 V and an input power of 2.64 W per fan. This design minimizes cable clutter while providing efficient cooling and aesthetic customization options for PC builds.
