Be quiet! Light Wings 140mm PWM Reverse White
Be quiet! Light Wings 140mm PWM Reverse White
The Be quiet! Light Wings 140mm PWM Reverse White fan combines an elegant look with quiet and efficient cooling. Its reverse blade design enables optimal airflow when mounted in the side or bottom positions of your case. The dual-sided ARGB lighting creates a striking visual effect that impresses from every angle. The fan is designed to achieve stable performance while maintaining very low noise levels.
Key features of the Be quiet! Light Wings 140mm PWM Reverse White fan
- Dual-sided ARGB lighting with twenty LEDs
- Reverse blade design suitable for bottom and side mounting
- Optimised blade shape for efficient airflow
- Maximum noise level of 25.5dB(A) for quiet operation
- Long-life rifle bearing with a lifespan of up to 60000 hours
- PWM function for automatic speed control
- Aesthetically impressive design visible from every angle
Dual-sided ARGB lighting
The Light Wings 140mm PWM Reverse White model is equipped with lighting on both the front and back. The subtly lit ring on the rear complements the more prominent front ring, creating an impressive lighting effect. Twenty individually controlled LEDs let you set a wide range of colour combinations and lighting modes, making it easy to match the fan's appearance with the design of your PC build.
Reverse blade design
The fan uses seven aerodynamically shaped blades in a reverse configuration. This system ensures optimal airflow when using the fan as an intake on the side or bottom of the case. This results in efficient heat dissipation even in more complex configurations where precise air direction is required.
Quiet and stable operation
The Light Wings 140mm PWM Reverse White fan reaches a maximum noise level of just 25.5dB(A), ensuring quiet operation even at full speed. The optimised impeller minimises vibrations and air turbulence, contributing to its stable performance. A high-quality rifle bearing provides a long lifespan of up to 60000 hours of continuous operation, helping the fan maintain its performance over the long term.
Intelligent speed control
Thanks to Pulse Width Modulation (PWM) technology, the fan can be connected to 4-pin controllers or motherboards that automatically regulate the speed according to the current temperatures. This system enables dynamic performance adjustment – increasing airflow under higher loads and maintaining maximum quietness at lower temperatures.
