A system to monitor the temperature of an integrated circuit and to dissipate heat generated thereby includes a heat sink to overlie the integrated circuit. A temperature sensor is located on the heat sink to detect the temperature adjacent the integrated circuit. Temperature signal conditioning circuitry is responsive to the temperature sensor and generates a temperature alarm signal when the temperature at the integrated circuit reaches a threshold level. A fan overlies the heat sink and draws air across and then away from the heat sink to cool it. A pressure transducer is mounted on the fan and detects air flow through the fan. Pressure signal conditioning circuitry is responsive to the pressure transducer and generates a pressure alarm signal when the air flow through the fan falls below a threshold level. Alarms are triggered by the temperature and pressure alarm signals to warn a user.
