Three-Fan ARGB Bundle

The be quiet! Light Wings LX 120mm PWM triple pack delivers three white 120mm case fans with addressable RGB illumination. Each unit features 16 LEDs shining through frosted blades and an illuminated hub for a distinctive lighting effect. The 4-pin PWM connectors allow precise speed control via motherboard headers. This bundle suits builders wanting coordinated airflow and lighting across multiple case positions.

Thermals and Acoustics

Seven optimised blades generate 51.5 CFM airflow at 1.34 mmH2O static pressure while spinning up to 1600 RPM. The rifle bearing keeps friction low, enabling a low starting RPM for very quiet operation at idle and light loads. Noise level varies with PWM duty cycle, so the fans remain subdued during typical desktop use. Rated lifetime reaches 60,000 hours of continuous running.

Sustained Load Behaviour

Under prolonged load the fans maintain their rated airflow and pressure figures without thermal throttling. The daisy-chain ARGB cable simplifies cable routing when all three units run together. Rifle-bearing durability supports extended high-RPM operation for the full 60,000-hour rating. Builders needing higher static pressure for dense radiators or restrictive filters should evaluate whether 1.34 mmH2O meets their specific cooling target.

Questions about this item

How do I connect the three fans and ARGB lighting to my motherboard?

Each fan uses a 4-pin PWM connector for power and an ARGB cable with daisy-chain support so you can link all three fans to a single 5 V ARGB header.

What maintenance or replacement will the rifle bearing need over time?

The rifle bearing is rated for 60000 operating hours; no lubrication is required, and the fan is replaced as a unit when noise or vibration increases.

At what point does the 1.34 mmH2O static pressure limit airflow in a dense radiator or filter stack?

The 1.34 mmH2O pressure rating is reached at the maximum 1600 RPM; beyond that the fan cannot push more air through restrictive obstacles.
