为了让用户了解硬件的工作状态,如温度、转速、电压等,通常有一个硬件主板上主要用于监测硬件监控芯片的工作状态。当硬件监控芯片是结合各种传感元件(电压、温度和速度),能自动采取保护措施或及时调整当硬件工作状态不正常的相应元件的工作参数,以保证所有的部件在正常情况下,计算机的工作。有温度控制芯片和通用硬件监控芯片等。

温度控制芯片:主流芯片可以支持两组以上的温度检测,并自动调整处理器的散热风扇的转速,温度超过一定的标准,从而降低CPU的温度。它也可以被强制关闭自动保护计算机系统超过设定温度时,常见的温度控制芯片的模拟设备adt7463等等。

Universal hardware monitoring chip: this chip usually integrates the function of super I/O (output / output management), which can be used to monitor the voltage, temperature and speed of the monitored object.The temperature monitoring needs to be matched with the temperature sensing element; the monitoring of the speed of the fan motor needs to be matched with the CPU or the radiating fan of the developing card.Hardware monitor chip more common with Winbond company W83697HF and W83627HF, SMSC, LPC47M172, ITE, IT8705F, IT8703F, ASUS, AS99172F (the chip at the same time to three group and three group system fan temperature monitoring system).
