Computer Fan Direction

The red arrow in the image points to an example of these markers.

Ceiling fan semarang. Unfortunately not all case fans have these arrows so it requires some additional investigation on your part to locate them. Likewise if the blade is angled down and the fan turns the opposite direction the reverse is true. If in doubt about the direction of air flow through your cpu fan apart from the labels and markings it may have you should be able to figure out from the direction of rotation which way the air is going.

By changing the direction a fan is mounted it can act as either an intake or exhaust. What if i cant see them. To avoid making your computer too loud use fewer or quieter fans.

You will also be able to identify the exhaust side as you will see power wires entering the fan motor. If a blade is angled down and the fan turns in the same direction as the blade angle it will blow forward. Air travels one way through a fan in one side and out the other.

The rear or exhaust side the side that the air comes out of of our fans will always be the side that houses the fan motor. The direction a fan blows air is always determined by a the shape of the blades sometimes called propellers and b the direction they turn. This fan is expelling heat directly from the cpu into the cases main airflow lane.

Also flashing multi color lights shouldnt be the main feature of your case fans. Many computer case fans today have a small arrow on one of the sides to indicate the direction the fan is moving air. Ideally you want to place an exhaust fan as close to the cpu as possible to quickly expel this hot air.

A side mounted fan expelling or drawing in air in a direction perpendicular to the motherboard might be useful here but not all cases support that.
