Fan control circuit
A fan control circuit drives and adjusts a rotation speed of a fan according to operating temperatures of a plurality of heat elements. The fan control circuit includes a plurality of temperature detection units, a temperature synthesizing unit, and a driving signal generation unit. Each of the temperature detection units respectively detects the operation temperature of each of the heat elements and outputs a temperature detection signal corresponding to each of the heat elements. The temperature synthesizing unit calculates and outputs mean temperature signals according to the plurality of temperature detection signals and a plurality of predetermined weighted values corresponding to the heat elements. The driving signal generation unit generates driving signals to the fan according to the mean temperature signals.
