Due to the self-heating nature of processors, cooling systems such as heat sinks, fans, or liquid cooling systems are usually necessary. While these systems allow the processor to run faster, they can take up a lot of space, use a lot of power, and can be very loud. As the temperature of the processor increases, the fan speed or liquid pump increases. This will increase the power consumption of the system as well as generate more audible noise to the displeasure of the user. More accurate temperature measurements can be used to keep the processor within a desired temperature range with minimal power consumption and audible noise from the cooling system.
