Pc Fan Static Pressure Measurement

Best 120mm 140mm static pressure fans for radiators heatsinks and restricted spaces in pc case.

Pc fan static pressure measurement.

Technicians typically measure static pressure in inches of water gauge. 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. Static pressure fans are designed to combat this with a different fin design.

Corsair for example sells quiet edition high static pressure fans. Insert the static pressure tip into the test port on the return side with the tip facing the airflow. Oriental motor s measuring equipment is connected to a computer providing extremely precise measurements in a short period of time. 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.

When you re defining the specifications for your industrial fan application one of the measurements you ll need is fan static pressure calculated as the difference between the pressure required at the discharge of the fan and the pressure at the inlet of the fan plus velocity pressure. By using two fans featuring the same characteristics together you can change the characteristics of the fans. An exhaust fan s static pressure also known as its pressure drop describes the resistance the fan must overcome. 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. Fan static pressure is the resistance pressure the fan has to blow against to move air in the desired direction. It s not much but when you re wanting to get the most out of your pc it s wise to choose the best fan for the job. Read the return or negative static pressure by moving the tube from the high to the low pressure port on the gauge.

This measurement is the pressure the fan is seeing on the supply side of the system. The fan blades of high static pressure fans are more curved and are directed towards the heat source. With high pressure static fans it has the capability to combat the resistance caused by placement. What is fan static pressure and why does it matter.
