Fan be quiet! LIGHT WINGS 140mm PWM Fan 140mm Reverse White

be quiet! LIGHT WINGS 140mm PWM Reverse White is a 140 mm fan for cases and radiators, aimed at cleaner and quieter configurations where aesthetics are as important as airflow. It operates in a range of 200–1300 RPM, giving you fine control from almost silent operation to serious cooling under load. With Addressable RGB lighting and a white housing, the fan is clearly oriented towards showcase builds. The reverse rotation direction is key if you want to see the RGB from the right side without sacrificing optimal airflow direction.

What you get is a combination of quiet cooling, decent airflow, and flexible control. With a maximum 51.4 CFM and static pressure of 1.1 mmH2O, the fan is suitable for both intake/exhaust in the case and for mounting on a radiator, where a bit more pressure is still required through the blades. The noise level of up to 25.5 dBA makes it suitable for quiet systems – at low RPM it practically gets lost in the remaining noise of the configuration. The Rifle Bearing bearing provides longer life and less vibration compared to basic sleeve solutions, which is important for 24/7 operation. Through the 4 PIN PWM connector, you control the RPM via the motherboard, while the 3 PIN 5V ARGB allows you to synchronize the lighting with other components or a controller. The fan operates at standard 12 V, with a consumption of up to 3.8 W and a current of 0.08 A, which is completely safe even at more loaded fan headers.

• Size 140 x 140 x 25 mm – larger blade for more air at lower speeds compared to 120 mm fans.
• Range 200–1300 RPM – from almost completely silent operation to sufficient cooling under higher load.
• Airflow 51.4 CFM – stable flow for effective intake or exhaust in medium and larger cases.
• Static pressure 1.1 mmH2O – allows use on radiators or dense filters without collapsing cooling.
• Noise level 25.5 dBA – focus on quiet operation, suitable for gaming and work systems where you don't want the fans to dominate the sound.
• Rifle Bearing bearing – better durability and lower vibrations for long-term 24/7 use.
• 4 PIN PWM + 3 PIN 5V ARGB – separate control of RPM and lighting effects via the motherboard or controller.
• Reverse rotation direction – optimized for situations where you want the RGB to be visible from the front, but the air to blow in the “correct” direction.
• White color and Addressable RGB – perfect addition to a white or light build with fully customizable lighting.
• 36 months warranty – long term that provides peace of mind for the reliability of the fan.

Who it is suitable for: if you are building a white or RGB-oriented build and want fans that are both quiet and visually complete, this model fits well. It is suitable for gaming systems where you care about low noise, as well as for AIO/radiator configurations, as long as you are not chasing extreme overclocking cooling. If you need maximum static pressure for very dense radiators, there are more aggressive models, but they are usually noisier.

The combination of 140 mm format, low noise, PWM control, and Addressable RGB in a white reverse design makes this be quiet! fan a particularly sensible choice for a clean, quiet, and good-looking build. You get balanced cooling without unnecessary noise, plus flexible RGB that easily connects with the rest of your configuration.
