## Key Features

- CORSAIR AirGuide Technology: Utilizes anti-vortex vanes to channel concentrated airflow and improve cooling, whether used as intake, exhaust, or mounted to a liquid cooling radiator or heatsink.
- Fluid Dynamic Bearing: Lubricant between the shaft and bearing greatly reduces friction, ensuring exceptional durability and minimal noise.
- Push Air Without Pushing the Decibels: A low-noise 140mm fan blade spins as quietly as 31.0 dBA.
- 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.
- Zero RPM Mode Support: Stops the fan entirely when sent a 0 RPM PWM signal, completely eliminating fan noise.
