Computer Fan Orientation

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.

Bathroom fan with led light. 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. 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. This is where the exhaust fans will take over dragging this warmer air out of the case.

The automatic pc fan speed controller software monitors temperatures from numerous. Airflow through the case is important so yes it matters. By changing the direction a fan is mounted it can act as either an intake or exhaust.

The side with the guardmotor support lastly the fan airflow can be identified by the arrow markings on the fan. Well you can also change or control fan speeds manually but the process is a bit tricky. You need to connect a manual fan controller to your windows system with knobs and this will set fans to different speeds.

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. Had some guy ask me which direction a fan worked this applies to most pc fans that you will see it does apply to the fan you were asking about doug. So it is best to go for the automatic option via software to control the computers fan speed.

Air travels one way through a fan in one side and out the other. Likewise if the blade is angled down and the fan turns the opposite direction the reverse is true. Also flashing multi color lights shouldnt be the main feature of your case fans.

This is the intel factory cooler for a socket 1150 system note its not much different than several other. To avoid making your computer too loud use fewer or quieter fans. If a blade is angled down and the fan turns in the same direction as the blade angle it will blow forward.

You will also be able to identify the exhaust side as you will see power wires entering the fan motor. The side fan forces air directly onto the hottest component the video card which is then swept up by the airstream produced by the front fan and escorted out of the rear exhaust fan. Ideally you want to place an exhaust fan as close to the cpu as possible to quickly expel this hot air.
