Experts in cooling fans know that as long as we disassemble the motor of the DC cooling fan, we can see that the DC cooling fans use a variable frequency motor, which can be identified from the position of the coil. The frequency conversion motor control circuit board, the control chip will integrate the DSP function and the driving device, simplifying the circuit structure. By programming the control chip, the motor speed can be changed.
Do you have such troubles? If the computer is used for a long time, the computer will respond slowly and the network will become stuck, but there is no problem in querying the network. So where is the problem? In fact, it is a computer cooling fan problem. If the computer is running for a long time, the temperature will rise, especially in summer, when the temperature is too high, the interface will recognize fatigue and slow down. To solve this problem, add a DC cooling fan to the computer.
