The CPU throttling feature helps to preserve power and reduce the heat that chip will generate. As a result, the battery life will be stretched and the CPU temperature will be lowered. What’s more, the CPU throttling contributes to the decreasing of cooling cost and keeping the system quieter.

MiniTool provides multiple solutions to keep your disk data safe and optimize the system performance.

What Causes CPU Throttling

CPU throttling or CPU usage drops will take place as a security measure for any system when:

  • It runs the risk of being overheated.
  • It doesn’t have an imperfect cooling system (isn’t able to dissipate heat quickly enough).
  • The overclocking has not been done properly.

Definitely, the most direct and root cause is: the system fails to dissipate heat fast enough.

Whenever the CPU or GPU takes a lot of load, it will get hot and reach a point where the cooling solution in your system fails to cope with the heat generated. At this time, the thermal throttling will kick in.
