A system includes a power supply unit, a central processing unit (CPU) power controller, a detecting circuit, an inductor, a thermal resistor, first and second field effect transistors (FETs), and first to third capacitors. The CPU power controller detects a voltage of the thermal resistor and compares the detected voltage with first and second preset values. If the detected voltage is greater than the first preset value and less than the second preset value, the CPU power controller outputs a first control signal to a base management controller (BMC) chip for signaling the BMC chip to control the fan to increase a speed. If the detected voltage is greater than the second preset value, the CPU controller outputs a second control signal to the CPU for signaling the CPU to regulate a working frequency or reduce a number of loads. |
