As heat dissipation fan experts know, as long as we dismantle the DC heat dissipation fan motor, we can see that the DC heat dissipation fan is a variable frequency motor, which can be identified from the location of the coil. The frequency conversion motor controls the circuit board, and the control chip integrates the function of DSP and the driving device, which simplifies the circuit structure. By programming the control chip, the speed of the motor can be changed.

Do you have such a problem, the computer used for a long time, the computer response will be slow, the network will change cards, query the network and no problem, then where is the problem? In fact, it is the problem of computer heat dissipation. If the computer runs for a long time, the temperature will rise. Especially in summer, if the temperature is too high, the interface will recognize fatigue and then slow down. To solve this problem, adding a DC fan to the computer can solve it.
