Be Quiet! Light Wings 140mm PWM High-Speed ARGB High Pressure Case Fan – BL075

Stunning Multi-Dimensional ARGB Illumination

The be quiet! Light Wings 140mm PWM high-speed fan is designed to bring an extraordinary visual flair to your custom PC build. Delivering breathtaking illumination through 20 individually addressable RGB LEDs, this fan features a brilliant dual-ring design. The front of the fan is highlighted by a bright, vibrant lighting ring, which perfectly contrasts with a subtle, elegant glow emitting from the rear. This dual-sided illumination ensures your hardware commands attention from every angle, giving you infinite possibilities to individualize your chassis through multiple colors and synchronized lighting modes.

Unrivaled High-Pressure Cooling for Heatsinks and Radiators

Aesthetic brilliance is backed by uncompromising thermal performance. Engineered specifically for demanding configurations, the Light Wings 140mm PWM high-speed is the ultimate solution for water-cooled radiators and dense air-cooled heatsinks. The meticulously crafted impeller features 9 silence-optimized fan blades designed to push a massive air volume of 71.7 CFM while generating an exceptional static air pressure of up to 2.3mm/H2O. Whether you are running intense gaming workloads or heavily overclocked professional applications, this fan easily pushes the necessary cool air through highly restrictive environments.

Acclaimed Silence Without Compromise

Even with its incredible speed and raw cooling power, this fan upholds the legendary acoustic excellence of the be quiet! brand. The heavily optimized impeller completely minimizes noise-generating air turbulences. Pushed to its absolute limit of 2,200 RPM, the fan outputs a remarkably low maximum noise level of just 31 dB(A). This incredible performance-to-noise ratio ensures you never have to sacrifice silent operation to achieve elite-tier cooling—proving that dynamic lighting is a beautiful addition to quiet, powerful hardware rather than a compromise.

Intelligent Real-Time PWM Speed Control

Achieve complete mastery over your system’s thermal footprint with integrated Pulse Width Modulation (PWM) technology. By plugging the fan into a compatible 4-pin controller or motherboard header, your system gains the ability to intelligently adjust fan speeds in real-time. It seamlessly ramps up rotational speed to quickly dissipate heat during heavy workloads, and automatically dials down to near-absolute silence during idle desktop use. Fortified with a high-grade rifle-bearing, this fan provides incredibly smooth operation and guarantees a staggering lifespan of up to 60,000 hours.
