Step 807 to the process that implements of step 809 is, when the temperature that Sensor monitoring arrives is higher than to disconnect threshold value,
Control chip needs the GPIO signal constantly exporting high level to keep the conducting of the first metal-oxide-semiconductor and the second metal-oxide-semiconductor, to ensure fan
Electricity can be got from bus.
Step 810：The temperature sending for current sensor determines rotating speed of target modification scope, by corresponding second interface
Send regulation and control instruction to corresponding fan；
The realization of this step is mainly, as shown in fig. 7, second interface d 70113 of control chip 7011 is directly connected to wind
Fan A70131；Second interface e 70114 of control chip 7011 is directly connected to fan B 70132；By sending regulation and control instruction such as
GPIO signal etc., realizes adjusting the rotating speed of fan, not only achieves as server radiating, and avoids fan and waste electric energy.
Step 811：According to the second corresponding relation, regulate and control corresponding rotation speed of the fan using regulation and control instruction, and execution step
804；
Step 812：Block the connection between at least one fan and bus, and execution step 804.
In addition, above-mentioned control chip can be BMC chip, then, the first interface in BMC chip and second interface
For GPIO interface, to realize the control to rotation speed of the fan by transmission GPIO signal, and fan can be controlled to run or stop.
