be quiet! Light Wings 140mm PWM Reverse White Fan - BL135
The be quiet! Light Wings 140mm PWM Reverse White Fan is a case fan built for builders who want both silent operation and RGB lighting without compromise. It pairs high airflow performance with a noise level of just 25.5 dB(A) and dual-ring ARGB illumination, making it suited to quiet builds and show cases alike.
Why this product
Quiet at full speed
Achieves only 25.5 dB(A) at maximum RPM thanks to 7 silence-optimized, reversed fan blades that reduce turbulence. PWM control lets your motherboard dial the speed down further when cooling demand is low.
Dual-ring RGB lighting
20 ARGB LEDs arranged in rings at both front and rear deliver visible light from every angle. Connects to any standard 3-pin ARGB header for full color and mode control.
High airflow design
Delivers 87.3 m³/h (51.4 CFM) at full speed with 1.1 mm H₂O static pressure, balancing intake and exhaust duty. Reversed blades make it ideal for side or bottom mounting.
Long-lived bearing
Rifle bearing rated for 60,000 hours of operation, backed by a 3-year manufacturer's warranty.

- EAN4260052192900
- Fits any standard 140mm case fan mount, including intake, exhaust and radiator positions.
- PWM speed control via any 4-pin PWM header on a motherboard or standalone controller.
- ARGB lighting via 3-pin ARGB header; works with most RGB software ecosystems.
- Reversed blades are optimized for intake duty (side or bottom); use as exhaust only if your case layout permits.
Best for
- Silent PC builds where cooling must not add audible noise
- Show cases and RGB-heavy builds that benefit from dual-ring lighting
- Builders using PWM-capable motherboards who want automatic speed ramping
- Long-term systems where bearing longevity and warranty matter
Trade-offs
- Extreme overclocking or sustained high-load cooling scenarios where maximum static pressure is critical
- Users restricted to DC or voltage-only fan control who need PWM's speed granularity
- Builds without RGB lighting support or interest in paying for LED features
Light Wings 140mm PWM Reverse White offers impressive illumination for a vibrant unique look, strong performance and quiet operation with efficient cooling. If you are looking for a quiet case fan with an impressive look from every angle, Light Wings 140mm PWM Reverse White is your fan of choice.
Light Wings 140mm PWM Reverse White offers ARGB lighting at the front and rear. The subtly lit ring at the back combined with the bright one at the front make for a magnificent appearance from every angle. 20 ARGB LEDs give you many opportunities to individualize your PC build.
With optimization for maximum airflow, Light Wings 140mm PWM Reverse White is the right choice for any case configuration that demands high cooling performance. Its 7 airflow-optimized and reversed fan blades not only reduce noise-generating turbulences but also ensure Light Wings 140mm PWM Reverse White provides the performance that is needed, even in demanding configurations.
A highly optimized impeller achieves the silent operation be quiet! is famous for. With a noise level of 25.5dB(A) at maximum fan speed, it proves that instead of being a replacement the lighting is an addon to very silent and powerful operation. All features combine to make Light Wings 140mm PWM Reverse White the fan of choice for silent show cases and gaming systems alike.
Pulse Width Modulation (PWM) allows compatible 4-pin controllers, including those built into many motherboards, to intelligently vary the speed and thus the noise level of the fan. With PWM the system can ramp up the cooling when it's needed or operate in maximum quiet mode when it's not.
