    • A data processing system includes a microprocessor connected to a circuit board and a fansink positioned on the microprocessor. The system includes dedicated code that causes the microprocessor to draw a predetermined level of power. A fan speed required to maintain the microprocessor at a targeted temperature while the microprocessor is drawing the predetermined power level is then determined. If the required fan speed level exceeds the expected fan speed, corrective action is taken. Exercising the microprocessor may include executing a dedicated piece of code continuously until the microprocessor temperature stabilizes. The system may further include a stored table of empirically determined expected fan speed values that is indicative of the expected fan speed for various ambient temperatures and microprocessor temperatures. Alternatively, the system may generate an algorithm during an initial boot of the system and use the algorithm to derive the expected fan speed values during subsequent operation.
    • 数据处理系统包括连接到电路板的微处理器和位于微处理器上的风扇。 该系统包括使微处理器画出预定水平的功率的专用代码。 然后确定微处理器在绘制预定功率水平时将微处理器保持在目标温度所需的风扇速度。 如果所需的风扇转速水平超过预期的风扇转速,则采取纠正措施。 执行微处理器可以包括连续地执行专用代码片,直到微处理器温度稳定。 系统还可以包括经验确定的预期风扇速度值的存储表,其表示各种环境温度和微处理器温度的预期风扇速度。 或者,系统可以在系统的初始引导期间生成算法,并且使用算法在随后的操作期间导出预期的风扇速度值。
