Seeing issues in the system such as reduction in speed of the CPU and stuttering when playing games.
What is throttling?
Throttling is a mechanism in Intel® Processors to reduce the clock speed when the temperature in the system reaches above TJ Max (or Tcase). This is to protect the processor and to indicate to the user that there is an overheating issue in their system that they need to monitor.
How to fix throttle?
For self-built PC with Intel® Boxed Processors, ensure the following:
For laptops, refer to OEM since the OEMs decide the power/current limits. Any throttling happening there would be completely based on how the OEM designs the laptop.
For overclocking: Note that the motherboard does have an impact on the ability to overclock. Some are better quality and more capable than others. Furthermore, the way the motherboard is set up also impacts the overclocking ability of a particular system (such as liquid cooler vs fan).
