Lian Li UNI SL-INF 120 ARGB Reverse Blade PWM Fan 120mm White - UF-RSLIN120-1W

This is the Lian Li UNI SL-INF 120 ARGB Reverse Blade – a 120 mm white case fan with addressable RGB and reverse rotation direction. It is ideal if you want a clean front or side look for the case, but without sacrificing airflow. In combination with a Fluid Dynamic Bearing bearing, a wide range of 200 – 2200 RPM, and decent static pressure, you get a fan that serves both for airflow and for denser radiators or filters. The ARGB lighting is 5V, so you can connect it to most modern motherboards and controllers.

What you get is a fan that is not just for show, but actually pushes air: up to 69.7 CFM at max. 2.2 mmH2O static pressure, which is fully sufficient for front intake through filters, as well as for radiators in more compact cases. The range from 200 to 2200 RPM allows you to tune it from almost silent idle to aggressive cooling under load, according to the fan curve in BIOS or software. The Reverse blade design is key if you want the RGB side to face you, but the air to enter the case – ideal for showcase builds. Power and control are achieved through a standard 4 pin PWM connector, while ARGB effects are via 3 pin 5V ADD-RGB, so integration with the rest of the build is easy.

• Standard size 120 mm, which makes it compatible with almost all modern cases and PC cooling radiators.
• Reverse rotation direction to see the beautiful ARGB side without sacrificing the correct airflow in the case.
• Addressable RGB lighting with 3 pin ADD-RGB 5V (V-D-NC-G) connector for full synchronization with the motherboard and other ARGB components.
• RPM control via 4 pin PWM, providing precise control from 200 – 2200 RPM relative to the system temperature.
• Maximum airflow up to 69.7 CFM / 118.42 m3/h, suitable for both intake and exhaust, or operation through filters and denser mesh panels.
• Static pressure up to 2.2 mmH2O, helping when mounted on a radiator or in front of dense dust filters.
• Fluid Dynamic Bearing bearing for better durability and smoother operation compared to cheaper sleeve bearings.
• Noise level up to 32.2 dBA at maximum RPM, while you can keep it noticeably quieter through an appropriate PWM profile.
• Operation at 12 V DC for the motor and 5 V DC for ARGB, fully standard for modern systems.
• White color and dimensions 120 x 122.1 x 25 mm, ideal for clean, light builds with an accent on visual design.

Who it is suitable for: if you are building a white or showcase build with a window and want the fans to look good from the side where air enters, this reverse blade model is exactly for you. It is also suitable for gaming configurations and more compact cases where you need a combination of airflow and static pressure. It is not the most sensible choice if you are chasing only the lowest price and RGB or the visual appearance of the system does not interest you at all.

The strongest point of this fan is the combination of reverse design, good airflow, and ARGB control with PWM management – you get a component that simultaneously cools well and contributes visually to the entire build.
