Then the previous article continues to say how the temperature sensing element of the temperature control cooling fan works. Take a dc cross flow fan for example, the fan control circuit will adjust the speed and power of the fan according to the signal from the temperature sensing element. When the temperature exceeds the threshold, the fan will operate at the maximum power to enhance the heat dissipation effect; When the temperature drops to a set range, the speed of the mini cross flow fan will gradually decrease to save energy and maintain a suitable temperature.

Through the working principle of the temperature sensing element, the temperature control cooling fan can automatically adjust the operating speed and power of the fan in time according to the change of the ambient temperature, so as to ensure the best heat dissipation effect of the device, and reduce power consumption and noise.

To sum up, the temperature sensing element plays a key role in the temperature control cooling fan, which can sense the change of the ambient temperature and realize the intelligent adjustment of the fan by transmitting signals to the fan control circuit. This makes the temperature-controlled cooling fan have great advantages in terms of equipment heat dissipation and energy saving, which brings convenience and comfort to our life and work.

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.
