Triple-pack 140mm ARGB fans

The be quiet! LIGHT WINGS LX triple pack supplies three 140mm PWM case fans with addressable RGB lighting. Each unit uses a rifle bearing rated for 60000 hours of operation. The bundle suits builders who want coordinated illumination across multiple intake or exhaust positions. Single-fan buyers should look elsewhere.

56.0 CFM airflow at 22.9 dBA

The key specification is the airflow-to-noise ratio: 56.0 CFM delivered at a maximum of 22.9 dBA. Seven optimised blades and a 25mm frame generate 0.90 mmH2O static pressure, making these fans effective for both unrestricted and slightly restrictive mounting locations. Systems needing higher static pressure will require different models.

Consistent output during extended runs

Rifle-bearing construction and a low starting RPM allow the fans to maintain their rated airflow and pressure over long sessions without acoustic degradation. The daisy-chain ARGB cable reduces cable clutter that can impede airflow in tightly packed builds. Users expecting continuously rising speeds under load should note the PWM curve stays within the published limits.

Questions about this item

What does the 56.0 CFM airflow rating mean once the fans are installed in my case?

The 56.0 CFM figure shows the maximum volume of air each fan can move; actual flow inside your case will be lower due to grille resistance, dust filters and component obstructions.

What does the 4-pin PWM connector control and what limits it in practice?

The 4-pin PWM connector lets the motherboard vary fan speed precisely; the practical limit is the fan's own top speed and the motherboard's PWM duty-cycle range.

Will the 140mm by 25mm dimensions fit my case's mounting points and clearance?

Each fan measures 140mm square and 25mm thick, matching the standard 140mm mounting pattern; verify your case has 140mm holes and at least 25mm depth between the frame and any components.
