be quiet! Light Wings LX, 140mm, PWM, Rifle Bearing, ARGB Fan Kit, 3-pack, Black

This triple pack contains 140mm cooling fans designed for high-speed performance across various system applications, including case ventilation and restricted environments such as radiators and heatsinks. Each fan measures 140 x 140 x 25 mm, adhering to standard mounting specifications. The fans are capable of reaching a maximum rotational speed of 1800 RPM, which results in a maximum airflow output of 75.3 CFM.

The blade structure is specifically optimized to generate 2.45 mmH₂O of static pressure, ensuring effective air movement through demanding cooling hardware. Speed control is implemented via a 4-pin Pulse Width Modulation (PWM) connector, allowing dynamic regulation of cooling output based on current system thermal loads. At maximum operational speed, the acoustic output is rated at 30.5 dB, supported by a durable Rifle Bearing mechanism that establishes a rated operational lifespan of 60,000 hours.

The fans also feature integrated multi-color addressable RGB illumination, utilizing 16 individual LEDs per unit for customizable lighting configurations. This lighting system connects via a standard 5V 3-pin ARGB header, facilitating synchronization with compatible motherboard software and controllers. The triple-pack configuration is suitable for users requiring uniform airflow and synchronized lighting across a complete system build.
