Patent number: 8253364Abstract: A method for controlling fan speed is disclosed. Firstly, a number of temperature ranges are defined. Each temperature range is associated with a corresponding fan speed. Each two adjacent temperature ranges overlap. The temperature of an electronic system is measured and is compared with the defined temperature ranges to determine whether it enters into a new range. If the measured temperature exceeds any one of the limits of a temperature range associated with the current fan speed, it enters into a new temperature range. The fan speed is adjusted to which is associated with the new entered temperature range. The overlap of each two adjacent temperature ranges covers the fluctuation of the temperature of the electronic system caused solely by the adjustment of fan speed caused by the traversing of the measured temperature between the two adjacent temperature ranges.Type: GrantFiled: March 26, 2009Date of Patent: August 28, 2012Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Chien-Fu Chen, Wan-Neng Su
