Do Static Pressure Fans Make A Difference?

Is airflow better than static pressure?

Let’s begin with airflow fans, which are your traditional big-blade fans that throw air around your PC.

Static pressure fans are designed to combat this with a different fin design.

This makes them better than high airflow counterparts at moving air through radiators, case meshes, and dust filters..

What does CFM vs static pressure mean?

(CFM is the volume at cubic feet per minute and static pressure is the resistance to flow measured across the fan and is usually measured in inches Water Gauge, the distance in a filled tube that water will be raised or lowered.

What does high static pressure mean?

If the kinetic energy is increased, the molecules begin to move faster and the pressure will rise. … So high fan static pressure means that the air has lost a lot of energy in its circuit through the lumber, and low fan static pressure means that a relatively small amount of energy has been lost.

Does stacking fans increase airflow?

Stacking fans will not increase performance. It will not increase the speed of air pushed through, in fact it may lower it, just because the front fan may disrupt the airflow.

How does static pressure affect airflow?

As you can see, air flow and static pressure have a negative correlation. When air flow increases, static pressure decreases; and when static pressure increases, air flow decreases.

What does static pressure mean for a fan?

Static Pressure is the resistance to airflow (friction) caused by the air moving through a pipe, duct, hose, filter, hood slots, air control dampers or louvers. … The temperature of the air going through the fan or blower will affect the density and performance of the fan or blower.

What is a good static pressure rating?

INTERPRETING TOTAL EXTERNAL STATIC PRESSURE The typical fan in a residential application is rated for a maximum pressure of 0.5 inch of water column (wc). … When you find the highest pressure or pressure drop, you’ll likely have found the source of your airflow problem.

Can I use a high static pressure fans as case fans?

They’re not good only for radiators, they just better for move air through restrictions, such as radiators or drive cages. They also function perfectly fine as case fans, but if the air flow is not restricted, AF fans will work better.

Are static pressure fans worth it?

Static pressure fans are only really needed on Radiators. They’re still great for all around use, but you can get by with stock airflow ones if you don’t want to spend extra for basically no gain. If you’re pulling through a filter something with higher static pressure will help.

What are static pressure fans good for?

High-pressure static fans are used on radiators, central processing unit (CPU) and graphic processing unit GPU coolers, in front of hard drives, and other places where airflow might otherwise be blocked by an object. Because of their high-pressure capability, they can overcome the restrictions caused by the blockage.

What’s the difference between static pressure fans and airflow fans?

Airflow indicates the volume of air that a fan can move per unit of time, and static pressure is the ability of a fan to push air against resistance. Higher static pressure means that the fan can even ventilate inside equipment with high mounting density.

Are static pressure fans good for rear of case?

Generally speaking, yes. Big airflow fans are just that: airflow fans. They make for poor intake fans. If one does make use of them for intake, open mesh has to be used.

Is a higher static pressure better?

yes higher is better, High static pressure fans are best of heatsinks and radiators. High airflow fans are best for open spaces. Keep in mind that those fans are quite loud, and you are trading performance for low noise.

What is a good static pressure?

Compare rated total external static pressure to equipment rated maximum total external static pressure. HVAC pressure diagnostics have similarities with blood pressure diagnostics. Good blood pressure is 120 over 80 by most standards. … Very low static pressure suggests a low fan speed or leakage in the duct system.

Why is high static pressure bad?

When the static pressure is too high, it means that airflow is restricted. This will make your HVAC system work harder to compensate for the poor airflow, and it will overwork itself. Your electricity bill will go up and the air conditioning system might get damaged.
