The F12 is exceptionally quiet and cost effective. The refined ninja-knife impeller design not only improves the laminar airflow, but it also lowers the noise level significantly. The ARCTIC F12 fan remains inaudible even running at full speed. The ARCTIC F12 fan is equipped with nine blades, increasing the airflow by 20% compared to generic seven-blade fans. The ARCTIC F12 has a standard frame, making it possible to install the fans either intaking or outtaking air in the PC case. The standard three-pin connector can easily be connected directly to mainboards.
