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

be quiet! LIGHT WINGS 140mm PWM Reverse is a 140 mm fan for cases and radiators that combines a quiet profile with addressable RGB lighting. The 'Reverse' rotation direction is specifically designed for front mounting on the case or on a radiator when you want to showcase the beautiful side with the RGB ring without sacrificing airflow. With up to 1300 RPM and a noise level of up to 25.5 dBA, this fan is aimed at balanced systems – gaming or work, where silence is important. The classic black color easily combines with almost any build, and the 36-month warranty provides peace of mind in the long term.

What you get

With a size of 140 x 140 x 25 mm, the fan offers a larger blade compared to 120 mm models, which helps move more air at lower speeds – here up to 51.4 CFM. The maximum static pressure of 1.1 mmH2O makes it suitable not only for cases but also for mounting on radiators, especially if you are aiming for a quieter RPM curve. The rifle bearing is optimized for longer life and less noise during operation compared to standard sleeve bearings. Thanks to the 4-pin PWM connector, you can dynamically control the speeds through the motherboard according to the CPU or GPU temperature, so it is almost inaudible at idle, and under load, it increases RPM only when necessary. Addressable RGB (3-pin 5V ARGB header or controller) gives you full control over effects and synchronization with the rest of the lighting in the system.

• Size 140 mm – larger blade for better airflow at lower noise, suitable for mid and full tower cases.
• Reverse rotation direction – optimized for front mounting or on a radiator, so the RGB side faces you without losing efficiency.
• RPM 200–1300 – wide range for quiet operation under low load and sufficient airflow when temperatures rise.
• Airflow 51.4 CFM and pressure 1.1 mmH2O – good balance between airflow and static pressure for cases with filters and denser radiators.
• Noise level up to 25.5 dBA – suitable for quiet gaming and work configurations where you don’t want the fans to be louder than the environment.
• Rifle Bearing – better durability and lower noise over time compared to standard sleeve bearings.
• 4-pin PWM + 3-pin 5V ARGB – full control over speeds and RGB lighting through the motherboard or external controller.
• Current 0.08 A at 12 V – low load on fan headers, convenient if you connect several fans to one controller or splitter.

Who it is suitable for

This fan is suitable if you are building a quiet gaming or workstation build with an emphasis on clean aesthetics and ARGB synchronization. It makes particular sense if you want front or radiator mounting with a visible RGB side thanks to the reverse rotation direction. It is not the best choice if you are looking for extreme static pressure for very dense radiators at high RPMs, but for real everyday scenarios, the balance between noise and cooling is very reasonable.

The combination of 140 mm format, quiet operation up to 25.5 dBA, and flexible addressable RGB control makes this be quiet! LIGHT WINGS 140mm PWM Reverse a very good foundation for a well-cooled and visually complete system.
