It is used to detect the installation of the cooling fan 3, thereby avoiding the overheating caused by the cooling fan 3 not performing the normal cooling effect Damage < Please refer to Figure 2. When the cooling fan of the central processing unit (not shown here), the cooling fan connector 21 is generally called the fan slot 1 and the pin 1 slot pin of a signal SENCpuFAN will show a high potential. Then, the signal SENCPUFAN passes through the amplifier as shown in Figure 3; then it is amplified to become a signal FANPS. Σ ^ Then, as shown in Figure 4, the signal FANPS is connected to a transistor to make Q77 on-state; if At this time, the user presses the system switch When the power is turned on, one of the system control chips 51 shown in FIG. 5 will send a signal -SUSB showing a high potential, so that a signal Q7 connected to this signal-smb also shows a conduction state, so that the transistor is connected. " A signal —PS — with an Ατχ power supply 41 shows a low-potential state, thereby enabling the ATX power supply 41 to start. Conversely, when the central processing unit cooling fan is not plugged in, the signal SENCPUFAN will show a low level. Potential state. After the signal SENCpUFAN is amplified by the amplifier 31 shown in Figure 3 into a signal FANPS, the control signal F ^ NPS is sent to the transistor Q77 shown in Figure 4, so that the Q77 is turned off. ^ If the user presses Press the system switch to power on, then the signal sent by the system control chip 51 as shown in Figure 5-SUSB is pulled up to M249089

The current high potential state 'causes transistor Q7 to also show a conducting state. However, due to the electricity, the body Q77 series is turned off, so that the signal-ps is in a high potential state '. Therefore, the Ατχ power supply 41 cannot be started normally, thereby protecting the computer system from being burned out. In another preferred embodiment of the present invention, when the system is turned on, the fan speed is detected through the system control chip 51 connected to one of the thermal fan connectors 21, ρ I ν 3 socket feet. In addition, the system chip 51, which is generally referred to as the south bridge, includes a detection and control device, which is connected to the cooling fan for detecting the rotation speed of the cooling fan. The detection and control device may also be designed in an I / 0 chip. Figure 2 and Figure exemplify the signal CPUFAN which connects ρ I Ν 3 and system chip 51 and represents the fan speed. The signal CPUFAN is a pulse signal, and the pulse frequency represents the rotation speed of the fan. Therefore, the system chip 5 can detect whether the rotation speed of the cooling fan 3 is too low. What ordinary people can easily infer is that the signal cpuFAN can also be replaced by SYSFAN, which represents the system fan speed, so as to detect whether the system wind f is operating normally. In addition, in order to detect whether the cooling fan 3 is operating normally, in addition to detecting whether the rotation speed of the cooling fan 3 is too low, it is also possible to design another detection speed decay rate. When the decay rate is too high, k ′ represents The performance of the cooling fan 3 is not good, and it will soon be unable to achieve the normal work. M249089 V. Creative instructions (9) When the fan speed is too low, it means that the cooling fan 3 is damaged and close to the damaged state, so at this time we use the BI 0S technique, which is BI 0S decides according to the signal CPUFAN, and the warning message "Your system fan is about to be damaged, please replace the fan to ensure the system is working properly" is displayed on the screen. And, is the system shut down? "Option, so that users can choose whether to shut down the system for fan replacement. When the user chooses to shut down the system, the system chip 5 shown in Figure 5 will pull the signal -SUSB low, which is the same as the current shutdown. The procedure is the same, the signal-SUSB shows a low potential, and this low-potential signal _susb is connected to the crystal Q7, as shown in Figure 4, so that the transistor Q7 shows a closed signal-PS_ON shows a high-potential state, which further makes Δτχ / cause 41 is closed for users to replace the fan. It should be explained in detail, the implementation and display of this creation. However, it should be understood that 'anything that does not depart from the spirit of this creation = decoration or change is the protection intended by this creation. What one does
