Cpu Fan Air Flow Direction

Airflow through the case is important so yes it matters.

Kennedy rechargeable fan. 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. If a blade is angled down and the fan turns in the same direction as the blade angle it will blow forward. Airflow direction of cpu fan thanks for the quick reply but theres no intake grills on the front side of the case.

The side with the guardmotor support lastly the fan airflow can be identified by the arrow markings on the fan. Likewise if the blade is angled down and the fan turns the opposite direction the reverse is true. Ideally you want to place an exhaust fan as close to the cpu as possible to quickly expel this hot air.

This means air is flowing into the case and hot air from the cpu. 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. This fan is expelling heat directly from the cpu into the cases main airflow lane.

There are several options for how a cpu cooler can exhaust heat from the cpu. This is the intel factory cooler for a socket 1150 system note its not much different than several other. You will also be able to identify the exhaust side as you will see power wires entering the fan motor.
