Much air flowing through small er spaces.

Static pressure fans vs high air flow.

All other components create. High flow low pressure. The more air you can move the more heat you can blow away. High airflow fans simply push as much air as possible while static pressure fans are specifically designed to tackle installations with heightened impedance and resistance.

The difference is that static pressure fans have a blade design optimized for good air flow at higher back pressure air flow resistance and often at low back pressures will deliver less air flow than a fan optimized for that latter situation so if you put the flow versus back pressure lines for both designs on the same graph they cross over at some intermediate pressure. 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. The 3 points depict possible scenarios where the fan will perform. We are often told by online pundits that you have to use a static pressure fan for your heatsink or radiator and that you have to use an airflow fan to intake or exhaust air from your chassis.

And when static pressure increases air flow decreases. Static pressure fans are usually best for locations where they have to push air through a tight area such as a hard drive bay or radiator. Linus explains the difference between high airflow and static p. The relationship between air flow and static pressure of a fan is shown in the graph above.

Much air flowing trough large spaces. Moves more air and become louder as it increases in speed the ideal fan would be a low rpm high cfm high static pressure. One could also compare the matter to water or any other fluid going trough a wide versus narrow tube. There s more to choosing the right pc fan than picking a size noise level and bearing type.

The more obstacles in the way of the air the more static pressure you want. For mechanical ventilation systems the fans create positive static pressure to move air through a given system. With static pressure fans vs airflow fans the fan blade structure is the main difference between these types of fans. Cfm air flow.

As you can see air flow and static pressure have a negative correlation. When air flow increases static pressure decreases. Air flow is the gaseous equivalent to the ampère and static pressure is the equivalent to the volt. Static pressure pressure.
