Computerkastventilator Lian Li Uni Fan 12RSLIN3W 120 mm Wit, 12 V, 0,2–2100 tpm, 2,66 mmH2O, FDB

Lian Li Uni Fan 12RSLIN3W is a 120 mm white computer case fan featuring an infinity mirror ARGB design and Fluid Dynamic Bearing (FDB). It operates at 12 V with a wide speed range from 0.2 to 2100 RPM and delivers improved airflow and static pressure for case and radiator cooling while keeping acoustic levels low.

Advantages

The fan combines a centered multi-layer infinity mirror with side-frame ARGB strips and an aluminum-trimmed geometric frame to produce layered lighting effects. Modular interlocking design and a removable keylock simplify installation and improve compatibility with radiator fittings. A reversible cable module and a single combined 7‑pin cable reduce cable clutter. Performance improvements provide higher airflow and static pressure at lower noise levels, and the unit uses a magnetic Fluid Dynamic Bearing for stability and longevity. L-Connect 3 software enables precise control of lighting and fan behavior, including a Start/Stop mode and motherboard speed sync.

Suitable for

• PC case cooling for gaming desktops and workstations
• Radiator fans in liquid cooling loops
• Compact or custom builds requiring low-noise operation
• RGB-focused builds that require synchronized ARGB effects

How to use

Install the fan into the case or radiator using the provided screws and, when applicable, connect multiple fans via the quick pin daisy-chain system. Attach the cable module to the fan cluster and plug the single 7‑pin cable into the included controller. Use the removable keylock and reversible cable module orientation to ensure clearance with radiator inlets and outlets. Configure fan speeds and lighting effects with L-Connect 3 or sync fan speed to the motherboard using PWM mode as required.

Recommendations

For radiator mounting, remove the interlocking key if it interferes with fittings and set the cable module orientation to minimize hose clearance issues. Use L-Connect 3 Start/Stop mode to stop fans automatically at low CPU/GPU temperatures (up to 50°C) for minimal acoustic operation, and consider grouping fans with the included controller to manage up to 16 fans per controller for consistent performance and lighting synchronization.
