## Summary description

The Lian Li 12SL1W3B is a 12 cm fan featuring a rotational speed range of 400 to 2000 RPM. It utilizes Fluid Dynamic Bearing technology for quiet and efficient operation, making it suitable for various cooling applications in computer cases. The fan's maximum air pressure is 2.44 mmH2O, ensuring effective airflow.

## Long description

The Lian Li 12SL1W3B is a 120 mm UNI FAN SL Wireless model in black that combines wireless control, a compact L-Wireless receiver, and Fluid Dynamic Bearing for balanced cooling performance. The fan supports a rotational speed range from 400 to 2000 RPM and is designed for easier cable management and unified control across compatible LIAN LI wireless devices. The LCD version includes a 1.6" display for system monitoring and custom images, while the LED version provides the same wireless control without the screen.
Advantages
The UNI FAN SL Wireless reduces cable clutter by using a 2.4 GHz L-Wireless controller to transmit lighting and PWM speed signals to fans, simplifying installation and freeing USB ports on the motherboard. Models offer both LED and LCD variants, two blade orientations (standard and reverse), and two color options (black and white). The fan uses a Fluid Dynamic Bearing for lower noise during long-term operation and includes an enhanced lighting layout with 40 LEDs (duo-zone) for richer lighting effects. The LCD variant supports direct display of system data and custom media via L-Connect 3.
Suitable for
Compact and mid-tower PC builds requiring 120 mm case fans
Builds where reduced cable clutter and wireless lighting control are preferred
Systems that benefit from integrated LCD monitoring or custom visual content
Key specifications
Model: 12SL1W3B (black)
Fan diameter: 120 mm
Speed range: 400–2000 RPM
Bearing type: Fluid Dynamic Bearing (FDB)
Maximum air pressure: 2.44 mmH2O (manufacturer data)
Wireless control: 2.4 GHz L-Wireless receiver (PWM and lighting)
LEDs: 40 total, duo-zoned lighting
LCD screen (on LCD variants): 1.6" integrated display (requires USB 9-pin connection)
How to use
Install the fan into the case using standard 120 mm mounting points. Connect the fan group by linking the PWM cable from the L-Wireless receiver to a motherboard 4-pin PWM header; the LCD receiver also requires a USB 9-pin cable to the motherboard. If using multiple fans, group them according to the receiver limits (up to 4 SL Wireless fans per group in supported mixes) and manage power by shortening cables on the receiver organizer as needed. For clusters mixing LED and LCD fans, use the LCD receiver. If a motherboard PWM port supplies unstable power (under 1 A) and causes flickering white light at startup, move the PWM connection to another 4-pin header or use the included 12V-to-SATA power adapter.
Usage recommendations
Use L-Connect 3 to configure lighting, fan curves, group naming and to upload custom LCD media. For larger setups, add a powered USB splitter or SATA-powered hub to increase the number of supported LCD fans (up to 6 with a passive USB splitter, up to 9 with SATA-powered hub), and note a single motherboard can support up to 20 UNI FAN SL LCD wireless fans when properly powered.
