Summary:To control the revolution of the fan requires the acquisition of temperature data collected by the first and second temperature sensing group, acquiring system temperature through the temperature data collected by the first temperature sensing group, getting the theoretical value of corresponding fan revolution speed based on the said system temperature, then adjusting the said theoretical value of the fan's revolution speed through the temperature data collected by the second temperature sensor and the pre set temperature threshold value, and last controlling the revolution speed of the fan based on the adjusted theoretical value. It also relates a fan revolution speed control device made of No.1 and No.2 temperature sensing groups, revolution speed calculating unit and control unit. It can provide simpler and reasonable way to determine the speed adjustment curve of the fan, supply in time treatment to each abnormal radiating conditions of each single plate.
