It is very rare for a CPU cooling fan to catch fire, but if it happens, it may be caused by several reasons:

Electrical failure: The wires of the cooling fan may short circuit, leading to overheating or even fire. This can be caused by aging wires, broken insulation, or improper installation.

Dust accumulation: After using the computer for a long time, a large amount of dust will accumulate in the cooling fan and heat sink. These dust will not only affect the heat dissipation effect, but also may cause a short circuit or cause the fan motor to overheat, and eventually cause a fire.

Fan bearing failure: If the bearing of the fan is badly worn, it may cause the fan to turn poorly or get stuck, increase the load on the fan motor, make the motor overheat, and eventually may catch fire.

Power supply problem: The power supply is unstable or the voltage is too high, which may cause the fan to work overloaded, which may cause a fire.

Inferior accessories: The use of inferior or substandard cooling fans, the quality of the material is not up to standard, may easily occur overheating or fire.

Chungfo's cpu fans have gone through strict quality control, you can rest assured to buy. We don't just do cpu fans, we also offer high quality mini cross flow fan and cross flow fan blade Wholesale to ensure that your equipment always maintains a good heat dissipation effect. Especially suitable for cross flow fan in air conditioner, help you create a safe and stable working environment!

During the use of the cooling fan, the influence of humidity on the life of the fan cannot be ignored. Especially in industrial and household appliances, such as air conditioning cross-flow fans, cross-flow cooling fans and metal cross flow fans, humidity will not only affect the efficiency of heat dissipation, but also may adversely affect the internal structure of the fan.

How does humidity affect the life of the cooling fan?

High humidity environments pose multiple challenges to the motors, bearings and metal components inside cooling fans. High humidity may cause internal fan components to rust or corrode. In particular, fans with metal shells or internal components, such as metal cross flow fans, are more susceptible to humidity.

Chungfo's way of coping

In order to deal with the potential threat of humidity to the life of the fan, Chungfo strictly selects moisture-proof and rust-proof materials in the design and manufacturing process of the fan. For example, Chungfo's cross flow fan in air conditioners pay attention to corrosion resistance in the selection of materials, and have passed a number of humidity tests to ensure their long-term operation in high-humidity environments such as air conditioning equipment. Our cross-flow cooling fans are also designed with a moisture-proof seal structure, which effectively prevents moisture from entering the motor part, further extending the life of the fan.

Humidity has a profound impact on the life of cooling fans, especially for products such as metal cross-flow fans, cross flow cooling fans and air conditioning cross-flow fans that are exposed to high humidity for a long time. By selecting high-quality anticorrosive materials and conducting rigorous humidity life testing, Chungfo provides customers with more durable and reliable cooling fan products.
