DETECTING SYSTEM AND METHOD FOR DETECTING FAN FAILURE

摘要

A detecting method for detecting fan failure in an electronic device is provided. The electronic device includes at least one fan and an air inlet structure. A first sensor is mounted on a central processing unit (CPU) and senses a first temperature value. A second sensor is mounted on the air inlet structure and senses a second temperature value. The detecting method includes steps of acquiring the first temperature value and the second temperature value; calculating a power value of the CPU; calculating a thermal resistance value based on the acquired first temperature value, the acquired second temperature value and the power value of the CPU; determining whether the calculated thermal resistance value is more than a predetermined thermal resistance value; and generating fan failure information when the calculated thermal resistance value is more than a predetermined thermal resistance value.
