Calculating CFM of controlled case fans Tags: Heatsinks Cases Fan Power Supplies Overclocking Last response: February 20, 2013 10:01 PM in Overclocking Share vfrgwb February 20, 2013 9:35:30 PM I have one case fan connected to my power supply and three others controlled by my motherboard. Knowing the airflow of each fan would be helpful in maintaining a slightly positive pressure in my case. Would simply multiplying the fan's speed percentage by its measured CFM yield a decent estimate? Thanks!
