Lian Li UNI FAN SL-INF 120 ARGB Fan 120mm PWM White - UF-SLIN120-1W

This is a 120 mm ARGB fan Lian Li UNI FAN SL-INF 120 – white, one piece, aimed at mid-range to high-end cases, where you care about both aesthetics and airflow. It combines Addressable RGB lighting with control via 4 pin PWM, allowing you to adjust the RPM based on load. With up to 2100 rpm and an airflow of 61.3 CFM, you get serious cooling for dense mesh front panels or radiators. The white color makes it a logical choice for light builds, where every ARGB shines maximally clean.

What you get

UNI FAN SL-INF 120 is designed as a system and case fan, so you can comfortably use it for both intake and exhaust airflow. The range of 200 – 2100 rpm allows you to keep the fan almost silent at idle and ramp it up when the CPU or GPU heats up. The maximum static pressure of 2.66 mmH2O means it performs better with filters, denser front panels, or when mounted on a radiator, compared to a typical low-pressure case fan. With a noise level of up to 29 dBA, it remains relatively civilized even at high speeds, especially if you manage it properly through PWM profiles. The addressable 3 pin 5V ARGB lighting gives you full control over the effects via a compatible controller or motherboard, without being tied to fixed modes.

• Classic standard size 120 mm and dimensions 120 x 122.1 x 25 mm, making it compatible with most cases, radiators, and mounting positions.
• Addressable RGB lighting with 3 pin ADD-RGB 5V (V-D-NC-G) connector for full software control of colors and effects.
• 4 pin PWM fan connector, allowing precise control of RPM between 200 – 2100 rpm based on temperature and profiles in BIOS or software.
• Airflow up to 61.3 CFM, sufficient for good overall ventilation and for configurations with more serious thermal loads.
• Maximum static pressure 2.66 mmH2O, suitable for use behind dust filters or on radiators, where air resistance is higher.
• Noise level up to 29 dBA, which feels moderate even in quieter builds with the right PWM profile.
• Fluid Dynamic Bearing bearing for longer life and smoother rotation compared to basic sleeve bearings, especially at higher speeds.
• Operating at 12 V DC for the motor and 5 V DC for ARGB with a maximum current of up to 0.78 A, which is important when sizing hubs and controllers.
• White color that fits perfectly in light or “all-white” builds, where RGB effects stand out maximally.

Who it is suitable for

This fan is suitable if you are building a visually organized ARGB build and want a balanced ratio of airflow, static pressure, and noise. It is a good choice for case airflow, as well as for mounting AIO or custom water radiators, as long as the connectors and control fit. If you are looking for absolutely silent operation under full load or a budget solution without RGB, here you pay for aesthetics, not just functionality.

The combination of addressable RGB, PWM control, 61.3 CFM airflow, and 2.66 mmH2O pressure in a white case fan makes this Lian Li UNI FAN SL-INF 120 a very good foundation for a clean, efficient, and visually complete build.
