Thermal management software controls the system cooling by reading the temperature measurement register (polling) and configuring the temperature alarm thresholds (interrupt-driven). As the temperature rises, or an alarm interrupt is detected, the software can turn on or increase the speed of the fan cooling the device. The software can also cool down the device by instructing the system manager to reduce computational activity or lower the clock rate to reduce power dissipation.
