Impressive airflow improvement the arctic f8 integrates some delicate features to improve the overall airflow and noise control management most 80mm and 92mm standard fans are equipped with 7 blades only but all arctic f8 fans including the 80mm and 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 signi
