Superior Cooling Performance and LED IlluminationCorsair Air Series LED high airflow PC case fans combine efficient, low-noise airflow with striking LED lighting. The custom-molded blades are designed for high-volume air delivery with less noise and turbulence than typical case fans. They are translucent, with a frosted texture, so the light from the four LEDs adds a dramatic effect.Tuned for High-Airflow, Large Volume CoolingAir Series AF fan models perform best in unrestricted spaces with at least 3cm of clearance, and they're ideal for mounting at the rear or top of your PC case as exhaust fans for your PC's motherboard and CPU, graphics accelerators, and other components that fill the case with heat. They work equally well as unrestricted intake fans for areas like side panels or bottom intakes.For high restriction areas like hard drive cages or in other tight spaces where there's less air volume, check out our Air Series SP models of high static pressure fans.Better Performance Than Standard Case FansAir Series AF fan models are designed to outperform standard case fans. The blades are custom-molded for optimal airflow, and they are ultra-thin for less noise and turbulence. The sleeved bearing system reduced vibration for quiet operation.
