From the appearance, you can judge the air inlet and air outlet of the Cooling Fan by following aspects:

1. Observe grid or filter: The air inlet is usually designed with grid or filter to prevent dust and debris from entering the inside 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 blade: The direction of the fan blade determines the direction of the fan's air inlet and outlet. Generally speaking, the side of the blade facing the air inlet means that the side is an air inlet, and the side of the blade facing the air outlet means that the side is an air outlet.

3. Observe the fan's logo or logo: Some cooling fans will have corresponding logo or logo at the air inlet or outlet to indicate their function. For example, the air inlet may be marked "IN" or "INTAKE", while the air outlet may be marked "OUT" or "EXHAUST".

4. Observe the position and layout of the fan: Usually, the air inlet of the cooling fan is located on the front or side of the fan, while the air outlet is located on the back or top of the fan. By observing the position and layout of the fan, we can initially determine which side is the air inlet and which side is the air outlet.

It should be noted that there may be some differences in cooling fans of different brands and models, so the above method is only a general reference, and the specific details need to be judged based on actual conditions. If you have any questions, you can refer to the fan's instructions or consult a relevant professional
