Computer power supply apparatus having fan control circuit for cooling standby power supply unit when computer is turned off and control method thereof

摘要

The present invention relates to a computer power supply device having a fan control circuit for cooling a standby power source unit in a state in which a computer is turned off and comprises: a power source unit for providing power to each part included in a computer main body while generating main power and standby power; a cooling control circuit; and a detection sensor. The present invention has an advantage of reducing the durability deterioration of parts included in the computer main body according to heating of the parts by driving a fan by means of the standby power of the power source unit so as to decrease the temperature or the current of the parts to a predetermined value or less if the temperature or the current of the parts increases to the predetermined value or more when an operation of the computer stops, thereby preventing a reduction in the durability and lifespan of the parts.
