  • Adaptive CPU cooling fan speed monitor device
    Patent number: 6407672
    Abstract: A device is provided which allows a personal computer user to monitor the operational parameters of the central processing unit's cooling fan. This device, called the CPU cooling fan speed monitor, characterizes the normal operating speed range of the CPU fan and the fan speed and provides warnings of improper fan speed. The fan speed monitor is a microcontroller-based device which has two principle modes of operation: the characterization mode; and the monitor mode. In the characterization mode, the fan speed monitor determines the “normal” operating speed range of the cooling fan. In the monitor mode, the fan speed monitor provides audible and visual indication of the operating speed of the CPU cooling fan.
