6 Summary

In summary, CPUs and GPUs generate a lot of heat during operation. Often large, loud, and expensive cooling systems are added to these devices to keep them within their temperature limits. Due to built-in safety margins under the inaccuracies of the temperature monitoring systems, these devices will throttle the clock rate, which will decrease the CPU or GPU performance and drive cooling systems harder. Accurate temperature monitoring for CPUs and GPUs protect processors from thermal damage, can cut down on cool system costs and power consumption, and optimize device performance. Throttling the processor just 2 °C earlier can lessen the benchmark scores by up to 4% on smartphones and 6% on PCs. Also, using remote temperature sensors or highly-accurate local temperature sensors ICs allows the user to optimize CPUs and GPUs performance and ensure safe operation.
