The ARCTIC F integrates some delicate features to improve the overall airflow & noise control management. Most 80mm & 92mm standard fans are equipped with 7 blades only but all ARCTIC F fans including the 80mm & 92mm ones come with 9 blades in order to create higher airflow efficiently. Moreover the refined "ninja-knife" impeller design not only improves the laminar airflow but it also lowers the noise level. Tested by hundreds of simulations the result is significant
- airflow is over 20% higher compared with a generic 7-blade case fan.
