Lian Li UNI FAN SL120 (120mm/58.5 CFM/1.96 mmH2O Static Pressure/1900 RPM Max/24.8 dBA/Fluid Dynamic Bearing/ARGB/PWM) Review
Lian Li UNI FAN SL120 120mm case fan, 58.5 CFM airflow, 1.96 mmH2O static pressure, 1900 RPM max, 24.8 dBA, Fluid Dynamic bearing, ARGB, PWM control. A daisy-chainable ARGB fan that eliminates the usual RGB/PWM cable clutter of multi-fan setups.
The UNI FAN SL120 solves a real problem with multi-fan ARGB builds: instead of routing a separate ARGB cable and PWM cable per fan, adjacent UNI FAN units physically connect fan-to-fan with a single link cable, needing just one PWM and one ARGB run back to the controller for an entire stack. The lighting runs through a full-frame diffusion ring rather than a handful of hub LEDs, giving a smoother glow.
Daisy-Chain Design
Each fan clips directly to its neighbor via a proprietary connector on the frame, carrying both power/PWM and ARGB signal between units, so a 3-fan stack only needs one cable run to the controller instead of six. It meaningfully cleans up cable routing behind the motherboard tray.
Lighting Quality
The full-perimeter ARGB ring diffuses light more evenly than hub-mounted LED clusters common on cheaper fans, giving a smoother halo effect that reads well through a case window without visible hot spots.
Comparison to Alternatives
Against the Lian Li SL-Infinity Wireless already in this catalog, the standard SL120 is wired rather than wireless but costs meaningfully less while keeping the same daisy-chain cable-management benefit. Compared to the Corsair QL120 RGB, the SL120 has slightly better static pressure and simpler cabling for multi-fan runs, though the QL's LED density is higher.

Expert rating9 / 10
The cable-management-friendly ARGB fan of choice for anyone building a multi-fan front or top intake.
Best for
- Multi-fan ARGB front or top intake
- Builders who hate rat's-nest RGB cabling
- Case-window showcase builds
Not for
- Single-fan installs (daisy-chain benefit is wasted)
- High-static-pressure radiator duty
- Non-RGB builds
