Description of the invention (4) Within a predetermined temperature, a pulse width modulation signal of 80% power will be output. This 8 (U power pulse width modulation signal will avoid the magnetic phase dead angle. Factor, and the built-in controller 26 outputs the same 80% power pulse width modulation signal with different bandwidth to start the cooling fan 22; 3. Repeat the second step to give the cooling fan 22 a pulse of different power. The wave width is adjusted to the wheat flood number (such as .75%, 70%, 65%) until the temperature of the central processing unit 20 drops to a predetermined temperature. At the time, it indicates that the cooling fan 22 has been operating normally. The advantage of this method is that When the temperature of the central processing unit 20 has not dropped, the built-in controller 26 will output a modulation signal different from the previous startup signal to the cooling fan 22 'to ensure that the cooling fan 22 can escape from the dead phase of the magnetic phase. Refer to Figure 3. Figure 3 is a block diagram of the power of the second computer system 2000 of the present invention. The difference between the computer system 2QG and the computer system is that the cooling fan 22 also includes a power input terminal 40 and a rotation ', = 42: while the built-in controller 2 6 is electrically connected to the cooling fan 2 input terminal 40 and the rotating feedback terminal 42. The oscillating thickness is the same as that of the first computer system 100, and when the computer system 200 is started, or the management unit 20 is sensed by temperature The temperature sensed by the device 28 exceeds the-pre = temple's central processing unit 2. The built-in controller 26 will be used to start the cooling fan 22 according to the method of the government fan 22 to maintain $ 8. Explanation (5) The normal operation of the system 2000. The startup method of the cooling fan 22 of the computer system 200 includes the following steps: 1 Using the built-in controller 2 6 to output a preset startup signal to the power of the cooling fan 2 2 The input terminal 40 is used to start the cooling fan 22, and the preset start signal can be a DC signal or a pulse width modulation signal; 2. If the built-in controller 26 cannot be replaced by the cooling fan 22 within a predetermined time Turning to the feedback terminal 42 and measuring that the cooling fan 22 has started to rotate, the built-in control panel 26 will output a pulse width modulation signal different from the previous starting signal to start the cooling fan 22; 3. Repeat the previous step Until the cooling fan 22 starts to rotate or when the fan is turned on The time length exceeds a predetermined time length. As described in the example of the first embodiment, the advantage of this method is that when the internal controller 2 6 cannot be measured by the rotation feedback end 4 2 of the cooling fan 22 2, the scatter = 22 has begun to rotate Then, the built-in controller 26 will output a pulse width modulation signal different from the previous one to activate the cooling fan to ensure that the thermal fan 22 can be separated from the dead phase of the magnetic phase. Compared with the conventional computer system, the heat The fan 22 can use the built-in control to continuously output different pulse widths. Therefore, the computer system 100 and 2000 will not be scattered by the computer system 100 and 2000 of the present invention, and 26 will be adjusted when the cooling fan 22 cannot be started. Change the signal to start the cooling fan 2 2 because the built-in controller 2 6 outputs DC 1225193
