Some customers, when choosing a cooling fan, hope to add an intelligent temperature control and speed adjustment function, so that the cooling fan can automatically adjust its own speed value according to the temperature, but why the small fan manufacturer does not have the temperature control and speed adjustment function?
1. The air volume of the small fan itself is small. If you design a low temperature and low speed, it is very likely that the heat dissipation effect will not be achieved.
2. The PCB of the small cooling fan is also very small, and the motor is small. If you want to add a temperature control resistor to the board signal, it is not convenient to add it due to space problems.
For customers who want the speed control function, Jingyangda generally recommends that customers use the three-line PWM speed control function. The cooling fan will have a clean appearance and stable speed. It can be designed according to different requirements of the customer.
