Along the whole Positive, Neutral, Negative pressure idea for case airflow, is determining positive pressure as simple as adding up the CFM of all inward facing fans, and measuring it against the CFM of all outward facing fans?
I want a bit of positive pressure going on, and I have the following fans going on:
Inward facing - 1 x 200mm fan pushing up to 110.1 CFM 2 x 120mm fans pushing up to 69 CFM
Outward facing - 1 x 140mm fan pushing up to 82.1 CFM 2 x 120mm fans pushing up to 69 CFM
I know there are other factors like screens/vents/dust collectors, but based on the fans mentioned above and assuming they are all controlled by the same controller, is it safe to assume positive pressure is achieved?
If not, can you guide me a bit on how I can make sure there is positive pressure without putting strain on anything?
Thank you for your time!
