Static pressure fans come with wider blades but the gaps between the main difference has a direct connection with how the fans are optimized because the cooling system works differently.
Pc fan static pressure vs airflow.
In case of static pressure and air flow fans there are a lot of difference.
High airflow and static pressure fans blow air through your pc but they do it in different ways.
When it has no restrictions.
Static pressure fans are fans that are for cpu coolers and radiators along with any other place that has airflow restrictions it has a lesser air flow performance but when it comes to radiators and cpu coolers it performs better than air flow optimized fans.
Using the fan in the wrong scenario will affect your cooling to a great extent.
High airflow fans are for open environments.
Static pressure fans have a focused flow.
With static pressure fans vs airflow fans the fan blade structure is the main difference between these types of fans.
Airflow is the amount of air which is the fan is capable of removing at its greatest rpm.
