An integrated circuit system includes an integrated circuit with a heat sink assembly including a fusible core. In the event that power dissipation by the integrated circuit threatens to exceed its safe operating range, the fusible core melts, absorbing the heat of fusion and delaying further temperature increases. A motor is repeatedly activated to attempt to rotate a shaft within the fusible core. When the core is solid, the shaft cannot be turned, but once it melts the shaft turns. The shafts motion is detected and used to trigger a reduction in the drive clock frequency of the integrated circuit. This reduces power consumption and dissipation until the integrated circuit cools and the heat sink core solidifies.
