CPU voltage and TDP varies greatly

[cperez]

I have a couple months old PC bought through a company where I selected all parts. Related to this question should be:

• Gigabyte Z590 UD AC motherboard
• Intel i7 11700KF CPU
• Corsair H80i pump

The PC came, unfortunately, with a custom BIOS which I had to flash back to Gigabyte's latest one, the F4.

I started looking into how the PC operates since, when gaming, the system gets quite hot. The first thing I realized was that the pump was not operating at full capacity since I can see that the fan is working like it does when the pc is idle.

I haven't had a Gigabyte motherboard in the past, nor a watercooler, but running the simplest Intel XTU benchmark worries me. Looking at XTU numbers:

• Temperature varies between ~40 and ~80 degrees
• Voltage varies between ~1.240V and ~1.460V
• TDP varies between ~80 and ~115W

See the below screenshot for reference (1 minute interval), where it can easily be seen the changes in temperature:

I compared this to a friend's system that is also a couple of months old, with:

• Asus Z590A motherboard
• Intel i7 11700KF CPU
• A watercooler pump with a 240mm fan (don't remember the model)

During the test, his system:

• Temperature varies between ~43 and ~46 degrees
• Voltage is stable around ~1.330V
• TDP is stable at ~120W

The only things I could conclude from what you have stated is that your friend's Asus motherboard and cooler sound like the better products.

Just saying,

Hello cperez

Thank you for posting on the Intel️® communities. The parameters provided are normal and not harmful to the processor, both systems are expected to behave differently as they use different components. Even between two computers with the exact same hardware, there will be differences.

The company that assembles the computer might include some adjustments that make it operate to those specifications, although it does not greatly affect performance.

You can check the processor specifications here:

• Intel® Core™ i7-11700KF Processor
  • https://ark.intel.com/content/www/us/en/ark/products/212048/intel-core-i711700kf-processor-16m-cache-up-to-5-00-ghz.html

 We can confirm if the system/processor is working as it should with the following reports:

• Intel® Processor Diagnostic Tool results:
  • https://www.intel.com/content/www/us/en/download/15951/19792/intel-processor-diagnostic-tool.html
• Intel® System Support Utility (Intel® SSU) results 
  • Download the Intel SSU https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows- 
  • Open the application and select "Everything" click on "Scan" to see the system and device information. By default, Intel® SSU will take you to the "Summary View".  
  • Click on the menu where it says "Summary" to change to "Detailed View".  
  • To save your scan, click on "Next", then "Save".

Hi David,

I have run both utility tools and both tell me that everything is OK, so I guess I shouldn't worry much about this.

Thank you!
