1. A protection device for a micro-controller chip package comprising:

  • a heat sink adapted to be mounted on the micro-controller chip package and having a plurality of surfaces for dissipating heat generated by the micro-controller chip package;

    a cooling fan assembly adapted to be mounted on said heat sink assembly for dispersing the heat dissipated by the heat sink into the surrounding atmosphere;

    a temperature sensor for converting a temperature of the heat sink into electrical signals and for outputting a voltage proportional to the temperature of the heat sink, said temperature sensor adapted to be placed on one of said surfaces of the heat sink assembly;

    a voltage comparator for comparing the voltage output from the temperature sensor with a reference voltage signal and outputting a comparator output voltage; and

    an alarm enabled by the comparator output voltage from the voltage comparator for generating an alarm signal.
