Abstract:
1. A dynamic temperature control method for a computer system which has at least a CPU, a microcontroller and a fan module, the method comprising the steps of: monitoring the microprocessor by the microcontroller to obtain a clock throttling-ratio status, a temperature parameter value and a power parameter value; comparing the temperature parameter value and a predetermined temperature initial value, temperature maximum value and temperature minimum value by the microcontroller, and comparing the power parameter value and a predetermined power initial value, and power setup value by the microcontroller to obtain a temperature variation rate and a power variation rate; if the temperature parameter value is between the temperature maximum value and the temperature minimum value, and the power parameter value is greater than or equal to the power setup value, the microcontroller rough-tunes the operating power of the fan module according to a predetermined maximum temperature variation rate and a rough-tuning setup value; if the temperature variation rate is below or equal to the maximum temperature variation rate, the microcontroller fine-tuning the operating power of the fan module according to a predetermined maximum power variation rate and a fine-tuning setup value; if the power variation rate is greater than the maximum power variation rate, and the power parameter value is below the power initial value, the microcontroller adjusting the fan module to reduce the operating power by the fine-tuning setup value; and storing the temperature parameter value and the power parameter value as the temperature initial value and the power initial value.
