Pros & Cons

Pros

✓ Three 140mm fans plus an ARGB hub in one box, no separate controller purchase
✓ 20 LEDs per fan light both the front and rear frame for glass-panel builds
✓ 31dB(A) at its full 2,200rpm high-speed rating
✓ Rifle bearing rated for 60,000 hours of operating life
✓ 4-pin PWM lets the motherboard scale speed to actual thermal load

Cons

✗ High-speed variant hits 2,200rpm, louder than the standard Light Wings tier
✗ ARGB hub syncs six components max, short for a heavily lit build
✗ 140mm size rules out the many cases and radiators built only for 120mm
✗ Adds ARGB plus PWM cabling per fan, so three fans means six leads to route

Manufacturer description

The be quiet! Light Wings 140mm PWM High Speed three-pack gives you a complete ARGB cooling front for a case build without shopping for a controller separately: three 140mm fans plus an ARGB hub ship in the box, and that hub synchronizes up to six ARGB components. Each fan carries 20 LEDs across the front and rear frame, so the glow reads from both sides in a glass-panel build rather than only through the intake side. The nine silence-optimized blades are shaped for high static pressure, which is what you want when air has to push through a radiator core or a dense heatsink fin stack instead…
