be quiet! Light Wings 140mm PWM High-Speed ARGB Fan 1800 RPM
The be quiet! Light Wings 140mm PWM High-Speed ARGB Fan is a 140mm case fan designed for builders who want both cooling performance and customizable RGB lighting. It suits PC enthusiasts looking to balance airflow with a visually striking build, and solves the problem of high-speed fans that are too loud by combining optimized blade geometry with a rifle bearing for quieter operation.
Why this product
Dual ARGB lighting, front and rear
20 individually addressable LEDs deliver customizable colors and effects on both the front and back, visible from any angle in your case.
High airflow at moderate noise
Produces 75.3 CFM at full speed while keeping noise to 30.5 dB(A), thanks to nine silence-optimized blades that minimize turbulence.
60,000-hour rifle bearing
The precision-engineered bearing is rated for 60,000 hours of operation and backs a full 3-year manufacturer's warranty.
PWM speed control
Connect to a PWM header for automatic fan curve management; supports voltage input from 5V to 13.2V for flexibility across different motherboards.

- Fits any standard 140mm fan mounting bracket or case slot (140 × 140 × 25 mm).
- PWM connector works with any motherboard fan header or hub that supports 4-pin PWM fans.
- ARGB lighting requires a 5V 3-pin ARGB header on your motherboard or a separate ARGB controller; many older boards lack this connector.
Best for
- RGB enthusiasts building high-end gaming or streaming PCs
- Builders who need quiet operation at high speeds
- Cases with visible side panels where dual-sided lighting matters
- Users running custom water loops who want intake fans that match the aesthetic
Trade-offs
- Minimal RGB use: overkill if you want simple cooling without customizable lighting
- Budget builds: higher cost than non-RGB 140mm fans with similar airflow
- Passive RGB systems: requires an RGB header or controller; will not work with non-addressable RGB cables or single-colour connectors
- Extremely tight spaces: 25 mm thickness is standard for 140mm, so very shallow mounting brackets may not accommodate it
Light Wings 140mm 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. 20 ARGB LEDs give you many opportunities to individualize your PC build.
If you are looking for a high-speed fan with an impressive look from every angle, Light Wings 140mm PWM high-speed is your fan of choice.
