Radiator stand fans are mainly used to dissipate heat from computers and other electronic devices.

A radiator stand fan usually consists of a heat sink, a fan and a stand. The heat sink is usually made of aluminium or copper and is used to absorb the heat generated by the device. The fan, on the other hand, takes the heat away from the radiator by rotating it and distributing it into the air. The bracket, on the other hand, is used to hold the radiator and fan in place and provide some support and stability.

When choosing a radiator support fan, there are several factors to consider:

1. Radiator size: The size of the radiator should match the cooling needs of the equipment. If the radiator size is too small, it may not be able to dissipate heat effectively, resulting in overheating of the device.

2. Fan speed: The higher the fan speed, the better the heat dissipation effect. However, at the same time, a high fan speed will also produce more noise. Therefore, you need to choose the right fan speed according to the cooling requirements and noise limitations of your device.

3. Fan type: Current PC fans mainly have 3-pin and 4-pin interfaces, and it is recommended to choose products with 4-pin interfaces. Fan types include DC fans and AC fans. DC fans are usually used for low-power devices, while AC fans are suitable for high power consumption devices.

4. Bracket type: Bracket types include one-word bracket, L bracket and U bracket, etc. Different bracket types are suitable for different applications. Different bracket types are suitable for different devices and cooling needs.

5. radiator material: radiator material includes aluminium, copper, iron and so on. Different materials have different heat dissipation effects, so you need to choose the right material according to your equipment's heat dissipation needs and budget.
