The be quiet! Light Wings 140mm PWM Reverse White fan is designed for PC builders seeking a blend of striking ARGB lighting and effective, quiet cooling. It offers a visually appealing setup with lighting on both sides and optimized blades for airflow and reduced noise. A key benefit is its ability to provide both performance and aesthetics without significant sound disruption. However, the reverse blade design means it's best suited for intake configurations to maximize its airflow benefits.

The maximum rotational speed for the Light Wings 140mm PWM Reverse White fan is 1300 RPM.
This fan uses a durable Rifle bearing, which contributes to its long Mean Time To Failure (MTTF).
While motherboard software is the most common method, some third-party ARGB controllers can also manage the lighting effects if your motherboard lacks sufficient headers or features.
The be quiet! Light Wings 140mm PWM Reverse White fan comes with a 3-year warranty.
While it offers good airflow, its primary design is for case cooling. For radiators requiring high static pressure, fans specifically designed for that purpose might be more effective. However, it can function on radiators, especially for builds prioritizing a clean aesthetic.
PWM stands for Pulse Width Modulation. It allows the fan speed to be precisely controlled by a 4-pin fan header on the motherboard, typically based on system temperature, enabling quieter operation at lower loads.
The fan comes with 4 mounting screws for installation.
Ensure the 4-pin PWM connector is securely seated on the motherboard header. Check that the motherboard BIOS/UEFI recognizes the fan header and is not disabled. Verify the fan is receiving power from the header.
Confirm the 3-pin ARGB connector is correctly plugged into a 5V ARGB header on the motherboard or controller. Ensure you are using compatible motherboard software or an ARGB controller to manage lighting effects. Try a different ARGB header if available.
Check for any obstructions around the fan blades (e.g., cables). Ensure the fan is securely mounted and not vibrating against the case. If noise persists at specific speeds, this might be related to resonance; try adjusting fan speed slightly.
Verify that the fan is connected to a PWM (4-pin) header, not a DC (3-pin) header, and that PWM mode is enabled in your motherboard's BIOS/UEFI settings. Ensure the fan curve in your BIOS or control software is set up correctly.
