Bottom line: The be quiet! Light Wings 140mm PWM Low Noise Premium ARGB Cooling Fan | 4-Pin | 3-Pack | Black | BL078 is a niche pick — read recent reviews before buying in the cooling & fans category, priced around $59.90. Compare close alternatives before committing.
The be quiet! Light Wings 140mm PWM ARGB cooling fan set puts three fans and an ARGB hub in one box, so a single purchase can handle a full front intake or a top exhaust row in most mid-tower builds. Each fan carries 20 LEDs split across the front and rear of the frame, which lights the blades from both sides instead of leaving a dark back face behind your radiator or dust filter. The bundled ARGB hub synchronizes up to six ARGB components, so these three fans plus additional strips or coolers can run one lighting profile together. Acoustics are where be quiet! spends its engineering budget…
