Is undervolting safe for a CPU?

[HellBoy]

Hello. Sometimes during gaming my CPU temperature goes up to 88 degrees Celsius. I heard that undervolting could be useful to bring temperature down a bit. Is undervolting completely safe for i9 13900K? Can it damage the hardware in any form? Can it damage the program how the chip functions by causing permenant glitches and bugs in its functionality even if the standard manufacturer voltage set back?

Please answer and help me.

Hello HellBoy,

Thank you for posting on the Intel communities. I see that you want to know if undervolting is safe for your Intel® Core™ i9-13900K Processor, I will be happy to help you.  

Altering clock frequency or voltage may void any product warranties and reduce stability, security, performance, and life of the processor and other components. For more information, What Is Undervolt Protection and How Does It Affect Overclocking in Intel® Extreme Tuning Utility (Intel® XTU)?

If you are worried about the processor temperature, I want to let you know that this is a normal temperature and should not damage the processor, and it supports up to 100°C.

"Altering clock frequency or voltage may void any product warranties and reduce stability, security, performance, and life of the processor and other components. For more information, What Is Undervolt Protection and How Does It Affect Overclocking in Intel® Extreme Tuning Utility (Intel® XTU)?" - This is the standard warning message from XTU and I asked this question here because I wanted to know why. I contacted intel platform instead of 3rd party platforms to get the proper answer to my simple question and instead I get a lazy answer. Please answer me and explain can undervolting damage the CPU and if yes then how can it damage it and what kind of damage can it cause on the CPU itself? Is it too hard to give me a proper answer? I am sorry if I am being a bit rude, but I want to find the answer to my question.

Hello HellBoy,

We have been working on the investigation, please find the answer of your questions below:

1. Undervolt reduces the CPU voltage and reduces energy consumption and heat which can make the processor not stable, so that is why altering clock frequency or voltage may damage or reduce the useful life of the processor and other system components, and may reduce system stability and performance which can be damaging the processor. We recommend using the system at default, and if you did any changes, we suggest loading the BIOS defaults setting to revert changes.
2. As mentioned previously, the maximum Tjuction of this CPU is 100°C, so it is expected that the CPU temperatures increase a little bit during high workloads like gaming. 

Let me know if you have further questions.
