Abstract:
A method and apparatus is disclosed for detecting the ineffectiveness or failure of a fan that is used to cool an electronic device. The method and apparatus use temperatures measured before and after the fan is energized to determine if the temperature trend is affected by the operation of the fan. If the trend is not substantially affected by the operation of the fan, it is determined that the fan is not operating effectively and the user may be notified.
