Computer case fan Lian Li 12RCL1W3B 120 mm, 12 V, 2150 RPM, 2.52 mmH2O, Fluid Dynamic Bearing, black

Lian Li 12RCL1W3B is a 120 mm computer case fan designed for chassis cooling. It features independently controllable dual-zone RGB lighting on the fan blades and side strips, a central aluminum nameplate, and a tool-free interlocking system for quick chainable installation. The fan uses a fluid dynamic bearing (FDB) and is available with standard or reverse blade orientation, delivering balanced airflow and static pressure while operating quietly.

Advantages

The fan provides layered RGB lighting with separate control of blades and side strips for refined visual effects. An aluminum center plate improves perceived build quality. The updated push-to-connect interlock enables screwless, fast installation and tidy chaining. Fluid dynamic bearing ensures quieter operation and longer lifespan, while integrated PWM detection and a 2-pin tail power header deliver stable 12V power and tidy cable routing.

Suitable for

• Desktop PC chassis cooling and airflow improvement
• RGB-focused builds requiring synchronized multi-zone lighting
• Compact or high-density setups needing 28 mm thick high-pressure fans
• Systems where quiet operation and long service life are important

How to use

Install the fan into a compatible 120 mm mounting location in your PC case. Use the tool-free UNI FAN interlocking system to chain multiple fans together without screws, aligning and pushing connectors until they click. Connect the 4-pin main header to the motherboard or PWM hub for automatic fan speed control and use the 2-pin tail header if additional power is required. Organize and adjust cable length with the built-in cable organizer and, if desired, use cable combs for cleaner wiring. Configure lighting and fan curves using the L-Connect 3 software or control groups via the L-Wireless Sync controller and 2.4 GHz USB dongle for wireless synchronization.

Recommendations

For optimal cooling performance maintain unobstructed intake and exhaust paths, set PWM curves in the motherboard or L-Connect 3 to balance noise and airflow, and group UNI FANs using the L-Wireless controller to synchronize lighting and speed across multiple devices.
