Where should airflow fans be placed?

Generally, you want the case fans in front of the case drawing in air while the fans at the rear blow air out. If your case has vents at the top, they should be placed as exhaust fans because hot air will rise. Side-mounted fans should be used for intake, though they often don’t have air filters.

Does it matter if fan is upside down?

Most ceiling fans have the ability to run in either direction. A fan doesn’t need to push air down to be effective. It’s all about air circulation. Running the ceiling fan in reverse in the winter helps circulate the warm air in the room for a evener temperature throughout the house.

How do I know which way my fan is?

The blades should move from the top left, then down to the right, and then back to the top. Looking for a more telltale sign? You should feel air movement while standing under the fan. If you do not feel air movement, the fan is spinning clockwise.

Negative internal air pressure Negative air pressure means that more air is going out than in. The exhaust fan(s) have a higher airflow rate compared to that of the intake fan(s).

Why do I need air filter in front of my fan?

A standard air filter can be installed in front of your intake fan (s) if your case doesn’t have one to ensure that cleaner and more dust-free air is drawn into your case.

Also, choose fans with ball bearing as opposed to a sleeve bearing, it will last much longer. In some cases, adding an extra fan at the upper rear of the case can help with keeping the CPU cooler.

Which is the best direction to mount an exhaust fan?

Do not mount exhaust fans on the bottom of the case; since hot air rises, a bottom-firing exhaust fan will be working against physics by expelling slightly cooler air instead of warmer air. The Intake-exhaust direction should go front-to-back and bottom-to-top. Side-mounted fans can be intake or exhaust, depending on the setup.

Negative internal air pressure Negative air pressure means that more air is going out than in. The exhaust fan(s) have a higher airflow rate compared to that of the intake fan(s).

Where does a ceiling fan need to be in order to have good airflow?

Your ceiling fan’s blades need to be at about 10 to 12 inches from the ceiling to produce the best airflow. Unless it is a hugger ceiling fan that is designed to be closer to the ceiling, if your typical fan is too close or too far from the ceiling it won’t move as much air.
