A NEW LEVEL OF COOLING The CORSAIR AF140 ELITE High-Performance 140mm PWM Fluid Dynamic Bearing Fan delivers PWM-controlled fan speeds from 400 RPM up to 1, 600 RPM for powerful cooling, near-silent operation, & exceptional durability. With a low-noise design, the AF140 ELITE spins as quietly as 31.0 d BA, while CORSAIR Air Guide technology with anti-vortex vanes channels airflow to concentrate your cooling. The AF140 ELITE’s fluid dynamic bearing ensures exceptional durability & reliable cooling performance while pushing up to 84.5 CFM of air with 1.73mm-H2O of static pressure even at full speed. Support for 0 RPM PWM signals enables the fan to stop completely, eliminating noise entirely. CORSAIR AIRGUIDE TECHNOLOGY Utilizes anti-vortex vanes to channel concentrated airflow & improve cooling, whether used as intake, exhaust, or mounted to a liquid cooling radiator or heatsink. FLUID DYNAMIC BEARING Lubricant between the shaft & bearing greatly reduces friction, ensuring exceptional durability & minimal noise. PUSH AIR WITHOUT PUSHING THE DECIBELS A low-noise 140mm fan blade spins as quietly as 31.0 d BA. ZERO RPM MODE SUPPORT Stops the fan entirely when sent a 0 RPM PWM signal, completely eliminating fan noise. KEEP YOUR SYSTEM COOL Powerful PWM-controlled fan speeds from 400 RPM up to 1, 600 RPM, pushing up to 84.5 CFM of air with 1.73mm-H2O of static pressure. UNIVERSAL 140MM SIZING Fits in case fan mounts, radiators, heatsinks, & more.
