Lian Li UNI FAN SL-INF Wireless Fan 120mm Black - 12SLIN1W1B

This Lian Li UNI FAN SL-INF Wireless 120mm Black is a 120 mm case fan aimed at more meaningful and organized builds, where you want a good balance between airflow, pressure, and aesthetics with addressable RGB lighting. It operates in a wide range of 200 – 2300 RPM, giving you flexibility – from almost silent operation to aggressive cooling when needed. With an airflow of up to 67 CFM and static pressure of 3.4 mmH2O, it performs well both as intake/exhaust and behind denser filters or radiators. Add in PWM control plus software management via L-Connect 3, and you get a fan that you can precisely control according to load scenarios.

What you get

With a Fluid Dynamic Bearing bearing, the fan is designed for longer life and lower noise compared to cheap sleeve solutions, especially at higher speeds. The range of 200 to 2300 RPM allows you to set aggressive curves for gaming and rendering, and then drop to low speeds in idle for quiet operation. With 67 CFM airflow and 3.4 mmH2O pressure, you can comfortably use it on dense mesh panels or thicker filters without choking the airflow. The Addressable RGB lighting at 5V with a separate 3-pin ADD-RGB connector gives you synchronization with the motherboard/controller and fine control through L-Connect 3, without being limited to static modes. The 4-pin PWM fan connectors, 3-pin 5V ARGB, and SATA power provide stable power and standard compatibility with modern motherboards and controllers.

• The fan is sized at 120 mm, which is the most common standard for cases and radiators, making it easy to fit into almost any build.
• It uses a Fluid Dynamic Bearing for better durability and quieter operation during extended sessions compared to regular sleeve bearings.
• The operating range of 200 – 2300 RPM allows for a very quiet profile in idle and aggressive cooling under load.
• With airflow up to 67 CFM and static pressure of 3.4 mmH2O, the fan is suitable for both intake/exhaust and more confined areas behind filters or radiators.
• The noise level of up to 29.2 dBA is reasonable for a fan with such a range of speeds, especially when controlled with a well-tuned PWM profile.
• The addressable RGB (Addressable RGB) lighting at 5V allows for detailed control of effects and synchronization with other components.
• Support for PWM control + L-Connect 3 software, along with 4-pin PWM, 3-pin 5V ARGB, and SATA power connectors, provides flexible integration into various systems.

Who it is suitable for

It is suitable for gaming and enthusiast builds where you want control over both noise and temperature, plus a tidy ARGB appearance. It is a good choice if you are already using or planning to use other Lian Li fans and want to manage them through L-Connect 3. If you are chasing an absolutely minimal budget and do not care about RGB or PWM, you are likely paying for features that you will not use.

The most sensible aspect of this fan is the combination of a wide RPM range, decent airflow and pressure, along with addressable RGB lighting and software control, allowing you to set it up exactly according to your build and habits.
