Triple Pack ARGB Fans

The be quiet! LIGHT WINGS LX 140mm PWM triple pack delivers three 140mm case fans in white. Each fan runs at 1200 RPM with a rifle bearing rated for 60000 hours. The 16 ARGB LEDs illuminate the frosted blades and hub. This bundle suits builders who want coordinated lighting and airflow from a single purchase.

PWM Daisy Chain Integration

Each fan uses a standard 4-pin PWM connector for motherboard speed control. An included ARGB cable supports daisy chaining so one header can drive the lighting for all three units. The 25mm thickness fits typical 140mm mounting points on radiators or case panels. Builders without a 5V ARGB header or with limited fan headers cannot use the lighting or individual speed control.

Sustained Quiet Operation

At full speed the fans move 56.0 CFM with a static pressure of 0.90 mmH2O while producing 22.9 dBA. The low starting RPM allows the curve to begin quietly and ramp only when thermals demand it. The rifle bearing maintains consistent acoustic performance over long sessions rather than degrading after a short burst.

Questions about this item

At 1200 RPM how loud is the fan under continuous load?

The LIGHT WINGS LX runs at 22.9 dBA at full speed so even during all-day operation the noise stays at a quiet whisper level.

What does the 25 mm thickness and rifle bearing mean for heat and power draw over long sessions?

At 25 mm thick the fan fits standard mounts and the rifle bearing is rated for 60000 hours keeping friction and heat low while PWM control matches power to demand.

Which motherboard headers or controllers are needed to run the ARGB lighting and PWM control on all three fans?

Each fan uses a 4-pin PWM connector for speed control and a 3-pin 5 V ARGB header with daisy-chain cables so one motherboard ARGB header can drive the whole triple pack.
