The CORSAIR ML140 PRO RGB PWM fan combines unrivaled performance and low noise operation with vibrant RGB lighting controlled in CORSAIR LINK software. By utilizing ultra-low friction magnetic levitation bearing technology, ML140 PRO RGB can deliver more airflow and higher static pressure at lower noise levels than traditional bearing fans, backed by a long-life five-year warranty. Four independent hub-mounted RGB LEDs output a vivid blast of light and colour, making it easy to match your systems style, and with a 400RPM to 1,200 RPM control range, its easy to equip your PC with quiet cooling, in any colour.Features- Magnetic Levitation Bearing: Dramatically reduces bearing friction by magnetically levitating the fan blade,producing lower noise and higher performance.- Dynamic RGB Lighting: Four independent ultra-bright center-mounted RGB LEDs output a vivid blast of light and colour.- Expansion Kit: This product is intended as an expansion of the ML120 PRO RGB LED 3 fan kit with Lighting Node PRO. The RGB functionality of this product requires a RGB lighting hub and Lighting Node PRO. - Complete PWM Control: Dynamically control fan speed from 400 RPM to 1,200 RPM to minimize noise or maximizeairflow.- Built to Last: Long lifespan with a five-year warranty.
