Cooling fans are essential cooling devices in computers, servers, switches, audio equipment and other electronic equipment. Choosing the right size of cooling fan is critical to the cooling effect and service life of your equipment. In this article, we will provide you with a cooling fan size selection guide to help you choose the most suitable cooling fan for your equipment.

First, we need to understand the size of the cooling fan. Cooling fan sizes are usually measured in inches, and common sizes include 3CM, 4CM, 5CM, 6CM, 7CM, 8CM, 92CM, 12CM, 14CM, 15CM, 20CM, 28CM, 33CM, and so on. When choosing the size of the cooling fan, you need to consider the power of the equipment and the amount of heat generated. Generally speaking, the higher the power of the equipment, the more heat it generates, and you need to choose a cooling fan with a larger size.

Secondly, we need to consider the airflow of the cooling fan. The airflow is an important factor in the cooling effect. The larger the airflow of the cooling fan, the better the cooling effect. However, the larger the air volume, the noise will also increase. Therefore, when choosing the size of the cooling fan, we need to choose the appropriate airflow according to the power of the equipment and the heat generated.

In addition, we also need to consider the noise of the cooling fan. The lower the noise of the cooling fan, the better, but it is related to the air volume, bearings and so on. When choosing the size of the cooling fan, you need to choose a cooling fan with less noise according to the equipment's usage environment and user needs.

Finally, we need to consider the cooling fan voltage, waterproof regulation speed, life expectancy and other factors. These factors will also affect the use of the cooling fan and the service life. When choosing the cooling fan size, these factors need to be considered comprehensively.

In short, the selection of cooling fan size needs to consider the power of the equipment and the amount of heat generated, wind volume, noise, voltage, waterproof regulation speed, life expectancy and other factors. When choosing cooling fan size, you need to choose the most suitable cooling fan according to the specific conditions of the equipment and user needs. If you have any questions about cooling fan size selection, we recommend consulting with a professional supplier to ensure that you choose the right cooling fan size.
