How to distinguish the air inlet and outlet of Computer fan from the appearance


The air inlet and outlet of Computer fan can be distinguished from the appearance in the following aspects:

1. Observation grid or filter screen: The air inlet is usually designed with a grid or filter screen to prevent dust and debris from entering the interior of the fan. These grids or filters are usually located on the front or side of the fan.

2. Observe the direction of the fan blades: The direction of the fan blades determines the inlet and outlet directions of the fan. Usually, the side with the blade facing the air inlet indicates that the side is the air inlet, while the side with the blade facing the air outlet indicates that the side is the air outlet.

3. Observe the identifications or signs of fans: some Computer fan will be marked with corresponding identifications or signs at the air inlet or air outlet to indicate their functions. For example, the air inlet may be labeled with "IN" or "INTAKE", while the air outlet may be labeled with "OUT" or "EXHAUST".

4. Observe the position and layout of the fan: Generally, the air inlet of the Computer fan is located at the front or side of the fan, and the air outlet is located at the back or top of the fan. By observing the position and layout of the fan, it is possible to preliminarily determine which side is the air inlet and which side is the air outlet.

It should be noted that there may be some differences between different brands and models of Computer fan, so the above methods are only general references, and the specific situation needs to be judged according to the actual situation. If you have any questions, you can refer to the fan manual or consult relevant professionals.
