摘要（英）：

The invention discloses a speed regulation circuit for a fan, comprising a switch power supply, a logic chip and a control module, wherein the logic chip is used for querying correspondent control switch array based on the correspondence of temperature and control switch array and sending the control switch array information to the control module when obtaining environment temperature of the fan;the control module is used for regulating the control switch array of the speed regulation circuit of the fan based on control switch array information; and the switch power supply is used for obtaining an output voltage value based on regulated speed regulation circuit of the fan and outputting the output voltage to the fan. In the invention, the efficiency of speed regulation circuit of the fanis improved and the energy consumption is saved.
