This article covers be quiet! ケースファン Light Wings LX 120mm PWM Reverse WHITE 1.

Overview

The be quiet! Light Wings LX 120mm PWM Reverse WHITE is a reverse-blade ARGB fan from the German cooling specialist be quiet!. Designed as an intake fan, its standout feature is the reversed blade orientation that displays the 16 addressable RGB LEDs on the hub directly through the matte blades, making the illumination clearly visible from inside the case. At a maximum speed of 1,500 RPM, it balances quiet operation with solid cooling performance. The fan uses a rifle bearing rated for 60,000 hours of continuous use, and the PWM connector allows for flexible speed control. The ARGB cable includes both input and output connectors, enabling daisy-chaining multiple Light Wings LX fans without needing separate controllers for each. The 120mm standard size fits most PC cases, making it an excellent choice for showcase builds where aesthetics matter.

Compatibility Guide

This fan fits any standard 120mm mounting position, including side, bottom, and top (as intake). It requires a 4-pin PWM header on your motherboard for power and speed control, and a 3-pin 5V ARGB header for lighting. The daisy-chain feature works only within the Light Wings LX series, but you can use separate ARGB headers for mixed-brand setups. Note that the fan is reverse rotation, so it is intended for intake only—do not use it as an exhaust. The included cable length is sufficient for most mid-tower cases, but for larger chassis you may need an extension. The ARGB connector is keyed for standard 5V headers; do not plug it into a 12V RGB header.

Product Info

Launched in mid-2025 and available through official Japanese distributors, the Light Wings LX Reverse WHITE retails for around ¥3,000 per unit. It carries a 3-year warranty. The fan sits in the mid-range premium segment, competing with other ARGB reverse fans while offering be quiet!'s signature low noise levels and build quality. Specifications include 12V DC operation, 1,500 RPM max speed, rifle bearing, 16 addressable LEDs, and a weight of approximately 200g. Airflow and static pressure figures are not officially disclosed, but the optimized blade design and air-sealing frame are tuned for quiet intake performance.

Best Use Cases

Showcase PC builds with glass panels: The reverse blade orientation ensures the ARGB lighting is fully visible from the interior, making side or bottom intake positions ideal for maximizing visual impact. Silent-focused systems: With PWM control and low noise operation even at 1,500 RPM, this fan is perfect for quiet builds where cooling demand is moderate. * Cable-managed daisy-chain setups: The built-in input/output ARGB connectors allow multiple Light Wings LX fans to be controlled through a single header, reducing cable clutter for a clean interior. ## Alternatives
Direct competitors include the Cooler Master MasterFan MF120 Halo 2 and Thermaltake Pure Plus 12 ARGB Reverse. The MF120 Halo 2 features dual-ring lighting but less blade illumination. The Thermaltake offers similar reverse blade design but tends to be slightly louder in operation. The Light Wings LX distinguishes itself with more uniform blade lighting and quieter acoustics, though it may fall short in raw airflow compared to higher-RPM alternatives. For users prioritizing silence and aesthetics over maximum cooling, it's the better choice.

Things to Consider

This is an intake-only fan—do not use it for exhaust; choose the standard rotational version of the Light Wings LX for outflow. At 1,500 RPM, it might not be optimal for high-density radiators or extremely warm components. If you need strong exhaust or high-static pressure, consider faster fans or the normal rotation model. ARGB daisy-chaining works only within the same be quiet! Light Wings LX series; mixing with other brands requires separate headers. The ARGB cable is a bit stiff, so allow some slack for routing. Overall, this fan excels in visual-oriented silent builds, but performance seekers may prefer alternatives with higher airflow ratings.
