Fan Lian Li SL-INF LCD FLEX Black Fan 120mm - 12SLIND1F1B

Lian Li SL-INF LCD FLEX Black 120mm is a premium 120mm case fan with an emphasis on visual effect and control. You get addressable RGB lighting, LCD functionality via an internal USB 2.0 connector, and serious airflow and static pressure parameters. With a speed range of 0, 350 ~ 2000 RPM, you can run it completely silently at idle or aggressively under load. The black color and modular approach make it particularly suitable for clean, organized builds.

What you get

This fan combines a stable airflow of 59.2 CFM and a maximum static pressure of 2.34 mmH2O, making it suitable for both intake/exhaust and radiators and denser mesh panels. Thanks to the Fluid Dynamic Bearing (FDB) bearing, you get better longevity and lower noise at the same speeds compared to basic sleeve bearings. Control is via a standard 4-pin PWM connector, so you can easily set fan curves from BIOS or software, and up to 29.5 dBA means that even at high speeds, the noise remains within reasonable limits. Addressable RGB plus a 3 PIN 5V ARGB connector give you full control over effects via the motherboard or controller, while the internal USB 2.0 9-pin is for the additional “smart” functionality. It operates on 12V DC for the motor and 5V DC for the lighting, so it is fully compatible with modern motherboards.

• 120 mm size – standard format that fits without issue in most modern cases for front, top, or rear positions.
• Speed 0, 350 ~ 2000 RPM – wide range for full control, from completely silent operation to aggressive cooling under load.
• Airflow 59.2 CFM – provides serious air circulation for powerful gaming or workstation systems.
• Static pressure 2.34 mmH2O – suitable for radiators and dense filters, where the fan needs to “push” air through resistance.
• Noise level up to 29.5 dBA – good balance between cooling and acoustics, suitable for a PC in a room where you work or sleep.
• Fluid Dynamic Bearing (FDB) – longer lifespan and lower vibrations compared to cheaper solutions with standard bearings.
• Addressable RGB + 3 PIN 5V ARGB and Internal USB 2.0 – full control of effects and LCD functionality via the motherboard and software.

Who it is suitable for

It is suitable for gaming and show builds where you want both good thermal performance and a serious visual accent with ARGB and LCD. It is a good choice for mid-range and high-end systems with a lot of heat, where you need both airflow and static pressure – for example, with dense front panels or water cooling. If you are looking for a very budget fan without lighting and extras, this is already above that class.

The combination of 120mm format, wide RPM range, FDB bearing, and addressable RGB with a rich set of connectors makes this Lian Li fan a very flexible choice for a modern, cleanly built, and well-cooled system.
