This article covers be quiet! ケースファン Light Wings LX 140mm PWM High Speed 3個パック 1800rpm Black 国内正規代理店品 BL130 LGT-WNG-LX.

Overview

The be quiet! Light Wings LX series represents the German brand's take on addressable RGB case fans, combining their signature silent operation with customizable lighting. This 3-pack of 140mm PWM High Speed fans spins up to 1800 RPM, delivering 127.9 m³/h of airflow while keeping noise at just 31 dBA. Each fan features 16 LEDs embedded in translucent blades, creating vibrant lighting effects that can be synchronized with your motherboard's ARGB ecosystem. The newly designed 7-blade impeller balances cooling performance and acoustics, while the rifle bearing ensures a lifespan of up to 60,000 hours. Positioned as a mid-to-high-end option, this triple-pack is ideal for builders who want to outfit the front or top of their case with matching 140mm fans. It's a compelling choice for anyone seeking both aesthetics and quiet operation.

Compatibility Guide

These are standard 140mm x 25mm case fans, compatible with any case that has 140mm fan mounts. They use a 4-pin PWM connector for speed control and a 3-pin 5V ARGB header for lighting. Ensure your motherboard has an ARGB header, or plan to use a separate controller. Check case clearance: make sure there's enough room for 140mm fans, especially if you have a large CPU cooler or a thick radiator. * The fans are 25mm thick, so they fit most standard fan mounts without issues.

Product Info

Released in late 2024, the 3-pack typically retails around ¥8,000–¥9,000 in Japan, which is competitive for ARGB 140mm fans. The warranty is 3 years. Market positioning: mid-to-high-end. The key selling point is the combination of be quiet!'s renowned silent operation with ARGB lighting. Cooling performance is solid, making it suitable for gaming rigs and workstations that need good airflow. Max speed: 1800 RPM Airflow: 127.9 m³/h Noise: 31 dBA Bearing: Rifle (60,000 hours) * Power: 3W at 12V DC

Best Use Cases

Gaming PC builders: If you want to add ARGB lighting to your build without sacrificing silence, this 3-pack is a great choice. The unified design looks clean when mounted on the front or top. Silence-oriented enthusiasts: be quiet! fans are known for low noise. At idle, PWM control keeps them nearly inaudible. Even at full speed, 31 dBA is relatively quiet. * Airflow-focused builders: 140mm fans move more air than 120mm ones, and the High Speed variant can push enough air for high-TDP components. Great for overclocked CPUs or powerful GPUs.

Things to Consider

No ARGB controller is included. If your motherboard lacks an ARGB header, you'll need to buy one separately. The High Speed model runs at 1800 RPM, which produces 31 dBA at full tilt. If absolute silence is your priority, consider the Standard Speed (1500 RPM) version. Make sure your case supports 140mm fans. Some smaller cases only accept 120mm. Competitors like Noctua NF-A14 offer slightly better cooling performance but lack ARGB. Corsair's ML140 series has similar features but tends to be pricier. The Light Wings LX strikes a good balance between features, performance, and cost. ## Alternatives
Direct competitors include the Corsair iCUE SP140 RGB ELITE 3-pack and the Lian Li UNI FAN SL140 V2 3-pack. Corsair fans integrate seamlessly with the iCUE ecosystem but cost more. Lian Li's daisy-chain design simplifies cable management, but be quiet! offers quieter operation. If you value silence and ARGB in equal measure, the Light Wings LX is a well-rounded pick.
