Lian Li SL-INF LCD FLEX Fan 120mm Black, Reverse

This Lian Li SL-INF LCD FLEX Fan 120mm Black, Reverse is a 120 mm case fan aimed at more advanced builds where cooling and aesthetics go hand in hand. You get addressable RGB, reverse rotation direction, and USB integration for finer software control. The combination of up to 1950 RPM, airflow of 57.89 CFM, and static pressure of 2.28 mmH2O makes it a good choice for both intake and exhaust, as well as for denser front panels. The black color and LCD concept are geared towards builds where you want a clean, organized, and modern look.

What You Get

At speeds between 350 – 1950 RPM, you can tune the fan from nearly silent operation to serious airflow when the system is under load. The airflow of 57.89 CFM, combined with 2.28 mmH2O static pressure, is especially useful if you have dense filters, a front mesh, or a radiator through which you need to "push" air. The Fluid Dynamic Bearing bearing helps for smoother rotation and longer life, which is important if your machine runs all day. The reverse rotation direction (Reverse) is convenient if you are chasing a specific visual orientation of the RGB and blades in the case. Thanks to the 4 pin PWM connector and USB 2.0 connection, you have precise control over the speeds and lighting via compatible software.

• Size 120 mm – standard form factor for most cases and radiators, easy to combine in multi-fan configurations.
• Addressable RGB – individually controllable LEDs via 3 pin ADD-RGB 5V (V-D-NC-G) for synchronization with the rest of the system lighting.
• Reverse rotation direction – allows you to orient the fan so that the "beautiful" side faces inward, without sacrificing the correct airflow.
• Speeds 350 – 1950 RPM – wide range for quiet operation at idle and aggressive cooling during gaming or rendering.
• Airflow 57.89 CFM and 2.28 mmH2O pressure – sufficient for effective system cooling and operation behind filters or radiators.
• Fluid Dynamic Bearing – lower friction and better durability compared to basic sleeve bearings, especially for 24/7 use.
• Connectors Fan 4 pin PWM + Internal USB 2.0 (9-pin) – convenient connection to the motherboard and additional control via software and RGB ecosystem.
• Noise level up to 31 dBA – balanced between cooling capability and acoustic comfort for gaming or work.

Who is it suitable for

This fan is for people who are doing more refined gaming or showcase builds and want synchronized RGB, software control, and good performance in cooling the case or the system as a whole. It is particularly meaningful if you have a glass panel and want the fans to look good from the "correct" side thanks to the reverse design. If you are looking for just the most budget-friendly solution without lighting and the aesthetics do not interest you, this model is probably overkill.

The strongest point here is the combination of 120 mm form factor, high airflow, and addressable RGB with reverse orientation, plus a reliable FDB bearing and 36 months warranty – a good balance between visual control and stable cooling.
