be quiet! Light Wings 120mm PWM High Speed 3-Pack BL077
The be quiet! Light Wings 120mm PWM High Speed 3-Pack brings ARGB lighting and controlled cooling to gaming and showcase builds. Each fan delivers 2.6 mm/H₂O air pressure at a measured 31 dB(A), making it suitable for both air-cooled and water-cooled systems where noise matters as much as visual presence.
Why this product
ARGB lighting at front and rear
18 LEDs per fan with a subtly lit ring at the back and bright ring at the front create a distinctive look from every angle. Included ARGB Hub synchronizes up to 6 components on a single connection.
High air pressure, remarkably quiet
2.6 mm/H₂O air pressure at just 31 dB(A) maximum noise makes it effective in demanding cooling scenarios without the noise penalty.
Motherboard PWM control
4-pin PWM connector lets compatible motherboards adjust fan speed automatically based on system load, reducing noise when cooling demand is low.
Long-life rifle bearing
60,000-hour lifespan at 25°C and three-year manufacturer's warranty provide confidence in sustained operation.
Easy ARGB synchronization
The included hub eliminates the need for multiple connections; mount it like an SSD or use the supplied adhesive tape, and control all lighting through a single cable.

- Works with any 120mm fan mount on PC cases, coolers and radiators.
- PWM control requires a 4-pin PWM connector on the motherboard or fan controller.
- ARGB lighting requires a 5V 3-pin ARGB header or the included ARGB Hub; the hub supports synchronization of up to 6 ARGB components.
- ARGB lighting control depends on motherboard BIOS support or third-party RGB software; basic PWM cooling works independently of lighting.
Best for
- Water-cooled builds needing high static pressure
- Gaming and showcase PCs where silent operation and visual impact both matter
- Builders who want ARGB lighting without adding extra hubs or cables
- Systems using modern motherboards with native PWM and ARGB headers
Trade-offs
- Passive or silent-at-all-costs setups. These fans require PWM control and motherboard support; they are not passive and are optimized for active cooling.
- Older systems without 4-pin PWM or 5V ARGB headers. Manual speed adjustment and lighting control require compatible connectors or additional adapters.
- Budgets where RGB lighting is unnecessary. The ARGB features and included hub add cost; non-RGB variants may offer better value.
Light Wings 120mm PWM high-speed 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.
18 ARGB LEDs give you many opportunities to individualize your PC build.
An ARGB Hub allows to use and synchronize up to 6 ARGB components at the same time. A user-friendly installation makes for an easy and convenient process, while the elegant all-black design of the ARGB Hub visually suits any PC case. It can be mounted like an SSD or anywhere else using the double-coated adhesive tape supplied.
With a remarkably high air pressure of up to 2.6mm/H2O, Light Wings 120mm PWM high-speed is the best choice for water-cooled and air-cooled systems alike. The nine airflow-optimized fan blades provide enough air pressure to make this fan perfect, even in demanding configurations.
A highly optimized fan frame and impeller achieve the silent operation be quiet! is famous for. With a noise level of just 31dB(A) at maximum fan speed, it proves that instead of being a replacement the lighting is an addon to silent and very powerful operation. All features combine to make Light Wings 120mm PWM high-speed 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.
If you are looking for quiet case fans with an impressive look from every angle, these three Light Wings 120mm PWM high-speed are your fans of choice.
