COMPUTING DEVICE AND METHOD FOR PROTECTING FAN OF COMPUTING DEVICE

摘要

In a method for protecting a fan of a computing device, firstly, a current supplied to the fan is read. Secondly, if the current supplied to the fan is more than or equal to a predefined current, a baseboard management controller(BMC) is controlled to send a pulse width modulation (PWM) signal to decrease a duty cycle of the fan by a predefined proportion, so that the current supplied to the fan is decreased. Thirdly, if the decreased current is more than or equal to the predefined current, the BMC is controlled to send the PWM signal to the fan to decrease the duty cycle of the fan by a predefined proportion, so as to decrease the decreased current.

1. A computing device, comprising:
a baseboard management controller (BMC); at least one processor; and a storage device storing a computer program including instructions that, which executed by the at least one processor, causes the at least one processor to: read a current supplied to the fan in every predefined time period; determine whether the current supplied to the fan is more than or equal to a predefined current; control the BMC to send a pulse width modulation(PWM) signal to the fan to decrease a duty cycle of the fan by a predefined proportion, so as to decrease the current supplied to the fan, if the current supplied to the fan is more than or equal to the predefined current; read the decreased current supplied to the fan through the BMC; control the BMC to send the PWM signal to the fan to decrease the duty cycle of the fan until the decreased current supplied to the fan is less than the predefined current.
