Intel 12900k stress test

Hi Everyone,

 

a few weeks ago I have built my new desktop pc, which is equipped with the intel 12900k processor. 

 

After I have finished building the pc I decided to run a stress test on all components to check that everything is fine and to make sure there are no problems.

 

Using Intel-xtu tool, I let stress run for 10 minutes. I observed that the core temps jump immediately to 100 (temperatures in Celcius and monitored with HWMonitor, core temp and msi center)  and remain in the range of 80-100 for the whole test. I also saw that there are two different temperature parameters, one is the socket temperature (measured around 60), and the other is the cpu core temperature (measured 77-99 as mentioned before). On top of that, during the whole test the cpu frequency remained at roughly 4.8GHz and the core voltage at 1.3V, even at high temperatures. At the end, according to the program, the test is passed. When running in normal mode (browsing, downloading, using small programs, etc.) the cpu temperatures are at around 36, both socket and core temperatures.

 

What is the difference between the socket temperature and core temperature?

 

Shouldn't the core voltage and the cpu frequency be reduced at such high temperatures? 

 

How is the cpu core temperature measured and how accurate are these measurements?

 

Shouldn't the pc shut off when the cpu reaches 100 celsius?

 

The pc has 3 case fans and a cpu cooler (be quite! dark rock pro 4). I have conducted a stress test using cinebench which led to the same results.

Hello sAz-I, I just received an update on this matter.


What is the difference between the socket temperature and core temperature?

The socket temperature will be the temperature between the CPU IHS and the fan and the core temperature will be the inside the die and it can vary from core to core,

 

Shouldn't the core voltage and the cpu frequency be reduced at such high temperatures? 

If the processor does not detect a possible damage, meaning that it can support it, then it will be keep it whenever is needed, for example, it is a normal behavior when doing a stress test.

 

How is the cpu core temperature measured and how accurate are these measurements?

The CPU comes with built-in thermal sensors, latest versions of Intel's processors have digital temperature sensors embedded within each core, this temperature is measured and read by the software, in this case, Intel® XTU and provides results.

We cannot warranty is 100% accurate, this depends on different factors like temperature from other PC components, temperature on location and assuming all components including the sensor is working fine we cannot provide an exact percentage of accuracy with measurements, explain user is very accurate but depends on factors mentioned before this can show small temperature differences

 

Shouldn't the pc shut off when the cpu reaches 100 celsius?

Similar answer to the second question; however, the maximum supported by this processor is 100C, so it is normal that it doesn't shut off immediately, higher that 100C, yes it could shut off.

 

It is important to mention that we don't validate 3rd party updates as we don't know how they measure the processor features, so we will only rely on Intel® software results. If you are not noticing shutdowns, BSODs, lags, freezes, or similar errors, then that's a sign of the CPU working as expected:
