Lian Li UNI FAN SL-INF 120 ARGB PWM Fan 120mm Black - UF-SLIN120-1B

This is a 120 mm Lian Li UNI FAN SL-INF 120 ARGB PWM fan in black color – a solid choice for a case or radiator if you want a combination of style and control over cooling. It works with 4 pin PWM for precise speed control and features 5V addressable RGB for synchronization with the rest of the system lighting. At up to 2100 RPM, it delivers serious airflow, while its pressure makes it suitable even for dense radiators. Add to that a Fluid Dynamic Bearing bearing, and you get a fan oriented towards quieter and longer operation compared to basic solutions.

What you get

With a range of 0 – 2100 RPM, you can configure your profiles so the fan is practically silent at idle and aggressive under load, when the CPU or GPU actually needs more air. The airflow of 61.3 CFM, combined with maximum static pressure of 2.66 mmH2O, is fully sufficient for mounting on a radiator or behind dense mesh/filters panels without getting exhausted. The noise level up to 29 dBA is a reasonable compromise for this class – you will hear it at maximum speeds, but it won't drown out your game or music. The Fluid Dynamic Bearing bearing helps with smoother rotation and fewer vibrations compared to cheaper sleeve solutions, which is a plus for 24/7 operation or if your case sits on the desk. Powered by 12 V DC for the motor and 5 V for the ARGB lighting, it is fully compatible with modern motherboards featuring 4 pin PWM and 3 pin 5V ARGB connectors.

• 120 mm form factor – a widely used size that easily fits into most ATX and mATX cases and on standard 120 mm radiators.
• Addressable RGB (5V 3 pin) – individually controllable lighting that you can synchronize with other ARGB components for a clean, coordinated build.
• Speeds 0 – 2100 RPM – a wide range allowing quiet mode at low load and aggressive cooling during gaming or rendering.
• Airflow 61.3 CFM – enough air for effective case ventilation or heat exhaust through a radiator.
• Static pressure 2.66 mmH2O – better efficiency through dense radiator fins or dust filters without a significant drop in cooling performance.
• Noise level 29 dBA – a balanced profile between performance and acoustics at maximum speeds.
• Fluid Dynamic Bearing bearing – longer lifespan and lower vibrations compared to basic bearings, suitable for long-term operation.
• Connectors 4 pin PWM + 5V 3 pin ARGB – direct connection to the motherboard for synchronized control of speeds and lighting.

Who is it suitable for

This fan is suitable if you are building a mid-range or high-end system and want both good airflow and ARGB style with precise PWM control. It works well both as a case fan and on a 120 mm radiator for CPU or AIO, especially if you need decent static pressure. If you are looking for the cheapest possible solution without lighting and noise doesn't interest you, this is not the most budget-friendly option.

The combination of ARGB, 2100 RPM, 61.3 CFM and Fluid Dynamic Bearing makes the black Lian Li UNI FAN SL-INF 120 fan not just another "RGB fin," but a real working element of the cooling system that you can configure exactly as you need.
