Can a small axial flow fan be designed with a PWM intelligent speed control function?

We know that an axial fan of the size of a computer CPU can be designed with a PWM function, and adding this function will give you a more comfortable feeling. When the frequency is used for a long time, the speed of the axial fan will become higher. On the contrary, the speed will be automatic. Down, theoretically, the life of the axial flow fan will be extended. So, can a smaller axial flow fan also be designed with this function? At present, the axial flow fan above 3CM can be added with the PWM intelligent speed control function. Yes, there are generally three lines, red is the positive line, black is the negative line, and yellow (or blue) is the PWM control function line, such as a 30*30*7 axial fan, we call it 3007 for short, and upwards are 3010, 3510 , 4010 can be done, of course, currently below 3CM, such as 20*20*6mm, 15*15*4mm, because the motor is very small, the built-in PCB board cannot design the PWM circuit, and there is not enough space, so this design is not available for the time being. Miniature axial flow fans with 3 wires are mostly FG functions, that is, the speed monitoring function. In addition, for small axial flow fans, the actual usage is relatively small. The main reason is that adding this function will increase the cost accordingly. A temperature control circuit can be added to the product to control the output voltage of the product, and it can also achieve a speed regulation function similar to PWM, because the voltage to the axial fan is reduced, and the speed will be reduced accordingly.

Many of our low-demand customers often go to the electronics market or the so-called wholesale department to buy cooling fans.

Automobile radiator fan factory is a cooling fan manufacturer integrating Ru0026D, production and sales.
Recently, we dealt with a case of changing the installation method of the cooling fan, which has a great impact on the cooling fan.

During normal use of any electronic product, due to the effect of current, there will be varying degrees of temperature rise inside the device, and when the temperature rise of the device exceeds a certain range, its life will be attenuated to varying degrees (for a long time, The safety of equipment operation will also be reduced).
Car cooling fan working position and its principle: cooling fan working principle 1.

The comprehensive laboratory of the automobile radiator fan factory has introduced new equipment-the thermal shock test box.
The commonly used cooling fan voltage is generally 12V, but some customers' products, such as temperature-controlled cooling fans, set a lower voltage for the cooling fan at low temperatures.
When we choose a cooling fan, especially for certain voltages that are not very stable or have several different voltage gears for speed adjustment, we need to understand the voltage range of the cooling fan, such as a cooling fan that works with a 12V DC voltage.
