    Abstract: A temperature detecting and control circuit with a first voltage dividing circuit, a second voltage dividing circuit, a fan rotary speed controller, and a comparator is described. The first voltage dividing circuit generates a first voltage. The second voltage dividing circuit generates a second voltage. The second voltage dividing circuit has a temperature sensitive element for detecting the temperature of hardware. The comparator compares the first voltage with the second voltage and then outputs the result to the fan rotary speed controller. When the fan rotary speed controller receives a first fan control signal, the fan is maintained at a first rotary speed. When the fan rotary speed controller receives a second fan control signal, the fan is maintained at a second rotary speed.
