Pc Fan Static Pressure

The fan blades of high static pressure fans are more curved and are directed towards the heat source.

Pc fan static pressure. I didn t need a static pressure fan but i did want a white bladed fan to test brightness with the phanteks halos vs a black bladed fan and this was actually one of the cheaper options so it made sense to go this route. An exhaust fan s static pressure also known as its pressure drop describes the resistance the fan must overcome. Technicians typically measure static pressure in inches of water gauge. Fan static pressure is the resistance pressure the fan has to blow against to move air in the desired direction.

A larger static pressure forces the fan to consume more power to expel the same amount of air. A high pressure static fan is used to cool components that require heavy usage. Static pressure fans are designed to pull or push air with extra force which is ideal for areas with more restricted airflow like a water cooling radiator or a large cpu cooler with lots of fins. Static pressure fans are designed to combat this with a different fin design.

Also there is a lesser gap between the adjacent. With high pressure static fans it has the capability to combat the resistance caused by placement. That said some basic tests on these high static pressure models show that their benefit is questionable in standard air cooled builds. Set on low these fans runs at 1 450 rpm and push 37 85 cfm while producing just 23 dba.

High pressure static fans are used on radiators central processing unit cpu and graphic processing unit gpu coolers in front of hard. Best 120mm 140mm static pressure fans for radiators heatsinks and restricted spaces in pc case. Unlike most pc components fans are mechanical systems. These high static pressure fans can deliver air at great force to the heat source and cools them down at a faster pace compared to standard fans.

High airflow fans can run into problems when installed in a case with restricted airflow that s what high static pressure fans are for. Pc components like radiators cpu gpu front of hard drives and other places that have poor airflow need high pressure static fans to maintain a cool system.
