Fans Lian Li SL-INF FLEX LCD Fan Pack 3-in-1 Black, Reverse - G9F.12RSLIND1F3B.00

The Lian Li SL-INF FLEX LCD Fan Pack 3-in-1 Black is a set of three 120 mm fans with reverse rotation and addressable RGB, aimed at more serious enthusiasts who care about both looks and functionality. The reverse design is especially convenient when you want a clean look on the RGB side, without looking at the frame and the back of the blades. The combination of a Fluid Dynamic Bearing (FDB) bearing and up to 1950 RPM gives you stable cooling without sacrificing longevity. The built-in 4 Pin, 5V ARGB, and internal USB 2.0 (9-pin) connectors provide you with flexible control and synchronization with the rest of the system.

What you get

You get three 120 mm fans that can be used for cooling a computer case as well as on a radiator with 120 mm mounting positions, so you cover both air and AIO configurations. The range of 0–1950 RPM means that you can run them completely stopped during a light idle profile or ramp them up significantly under load when the GPU and CPU heat up. With an airflow of up to 56.89 CFM and a maximum pressure of 2.28 mmH2O, the fans are strong enough for radiators and denser mesh panels. The noise level of up to 31 dBA is a reasonable compromise at maximum RPM, and the FDB bearing helps for smoother operation and less parasitic noise in the long run. Through the Internal USB 2.0 9-pin and 5V ARGB connector, you can integrate control and lighting via compatible software and synchronize the RGB effects with the other components.

• A pack of 3 x 120 mm fans, which is enough for a full front intake or a 360 mm radiator with 120 mm mounting positions.
• Reverse rotation, ideal when you want the RGB side to face outward but maintain the correct airflow in the case.
• Addressable RGB lighting, which allows individual control of light effects via 5V ARGB and software.
• Speed 0–1950 RPM, giving you a wide range from completely silent operation to aggressive cooling under load.
• Maximum airflow 56.89 CFM and pressure 2.28 mmH2O for effective operation both on a radiator and behind filters and dense panels.
• Noise level up to 31 dBA, which places the fans in a decent balance between performance and acoustic comfort.
• Fluid Dynamic Bearing (FDB) bearing for a longer lifespan and smoother rotation compared to more basic bearing types.
• Combination of 4 Pin, 5V ARGB, and USB 2.0 (9-pin) connectors for precise control of speed and lighting via the bottom and an internal USB header.
• 36-month warranty from Lian Li, which is a good duration for a component that operates constantly.

Who it is suitable for

This pack is suitable if you are building a more visually oriented build with a transparent panel and want the RGB fans to look equally clean as both intake and exhaust. It becomes meaningless if you need a completely budget solution without the need for addressable RGB and USB integration – in such a case, there are simpler fans. But if you need a combination of aesthetics, control, and decent airflow for a case or a 120 mm radiator, you hit the target exactly.

The most meaningful thing here is how Lian Li combines reverse design, ARGB, and a wide RPM range in a 3-in-1 pack that can cover both the cooling and the look of your entire build.
