i5-13600kf thermal throttling at low temps

[jehoffy]

Dear Intel Community,

System Info:

CPU: i5-13600kf with Contact Frame

Mainboard: Gigabyte Z790 Aorus Elite AX DDR4 (newest BIOS Version)

RAM: 32 GB G.Skill 3600 MHz Cl18

CPU Cooling: be quiet! Pure Loop 2 360mm

GPU: Radeon RX 6900 XT

PSU: be quiet! Pure Power 12 1000W

Case: NZXT H7 Flow

If I start stress testing my CPU via Intel XTU or Cinebench 2024 i can almost instantly see thermal throttling, even though my CPU is running at avg. of 70°C on all Cores. I also checked the VRM temps and they stay around 50°C.

Can somebody explain to me why my CPU is thermal throttling even though it is far from TJmax and what settings i need to change/check?

My XTU settings are all on default, so no Overclocking is applied.

Thanks for your help.

Greetings

Hi Jehoffy,

Thank you for posting in Intel Communities.

Getting a thermal throttling notification on 70 degrees Celsius can be perplexing. We will work with you to check this one out.

Please allow us to ask the following information that we will use to see what is going on with the system:

1. In Intel XTU, there is a customize option (wrench icon) on the right pane where you can find the thermal throttling reading.  Please enable temperature for every core, then run a stress test, please check if a core is getting to 100 degrees Celsius.

2.  Does the CPU frequency deteriorate when you get this thermal throttling messages?

3. Please check if you have logs saved on C:\ProgramData\Intel\Intel Extreme Tuning Utility\Logs.

3.  Although thermal throttling gets activated, if it only happens for a very short time, it can be still considered normal. On the XTU results, there is a timeframe from when the thermal throttling is activated. What is the longest time that you got?

4. It would really help us if we can get more information about your system. Please download and run our Intel® System Support Utility from this page, https://www.intel.com/content/www/us/en/download/18377/intel-system-support-utility-for-windows.html. To run it, please press "Scan". After the scan is finished, click next and there will be a save button, giving you an option to save the logs to a text file, please do so and attach the file on your reply. You can refer to How to get the Intel® System Support Utility Logs on Windows* https://www.intel.com/content/www/us/en/support/articles/000057926/memory-and-storage.html for instructions.

We will be waiting for your post with all the information that we asked.

Hi Alfred,

i will try to answer your questions as good as i can.

1. I checked out every core via XTU and also HWINFO. None of the cores was hitting anywhere near the 100° TJMax, i think the highest i saw was around 85° and averages were around 70-75°.

2. The CPU frequency is constantly moving up and down, but only by like 400Mhz max. So no massive drops.

3. If i run a 10 min CPU Stresstest i have like 1 min without throttling and then it will be at like over 50% for the rest of the time.

If i check HWINFO while throttling then i see IA PROCHOT constantly on Yes.

I will include a short log file where ou can see when the throttling starts.

If you  need longer log files, i will also provide these.

I also added my System Information.

Best Regards,

Jan

Edit: I did a 30 minute stresstest and ended up with a thermal throttle percentage of over 75% with a max. core temperature of 84°.

I will also include the log file.

Hi Jehoffy,

Thank you for the detailed response and information that you provided.

After checking, it seems that your board’s threshold for unsafe temperature for the CPU is set aggressively. The temperature readings that you are getting should not trigger a thermal throttling signal.

For this reason, please try the following:

1. Included with your BIOS update are “Intel Default Settings”. Please load these settings and check if you have any improvements.

2. Should it still be the same, after checking your system’s BIOS manual, these parameters could be what the board uses to set the thermal throttling temperature:

a. CPU Over Temperature Protection or TJ Max Offset Value: Set it to 0

b. CPU Thermal Monitor: Try to activate it and see if it allows you to set temperature, if not set it to Auto.

 3. If the issue persists, we suggest that you reach out to Gigabyte support to ask on what BIOS parameters affect the thermal throttling temperature.

We will wait for your feedback regarding our suggestions.

Hi Jehoffy,

We are just following up.

It looks like you need more time to carry out the recommendations that we have provided.

Hi Alfredo,

sorry for the delay, I had already written an answer, but I think something went wrong while sending.

I had the Intel default settings loaded the whole time, so nothing changed there.

For the CPU Over Temperature Protection I can set a value between 80-115 degrees. I tried out 100 degrees, as i read this is my CPU’s specification for TJmax.

I also enabled CPU Thermal Monitor, but I wasn’t able to adjust any values there.

The outcome is still the same as before, I still get throttling almost instantly.

I also tried setting CPU Over Temperature Protection to 115 degrees and disabled CPU Thermal Monitor, but this also didn’t change anything.

I have already opened a support ticket on the Gigabyte support site, referring to this post.

If you have anymore ideas, please let me know

Best Regards

Hi Jehoffy,

Thank you for your response.

Since our suggestion still did not work, there may be a possible motherboard sensor fault.

We will wait for your update.

Hi Alfred,

I don’t think that a motherboard sensor fault is causing the issue, because I already changed the motherboard for a brand new one. I think it’s really unrealistic that two brand new motherboards have the same sensor fault.

I guess the problem is software sided.

I will wait for the response from Gigabyte and come back here if I have new informations.

Best regards

Hi Jehoffy,

Thank you for providing that you have also changed motherboards.

If you already experienced this on two motherboards, I agree with you that it is unlikely that it is a sensor failure. I hope it can be amended by just a simple BIOS change by Gigabyte.

While you are checking with your motherboard manufacturer, we will also check internally if this is a CPU issue. Please allow us some time to check on this. We will revert to you once we have any updates.

Hi Alfred,

just quickly wanted to let you know that i was able to firgure out the problem with the help of the Gigabyte support.

I think the problem was that the Intel defaults don´t work like intended on this board, their advice was to do an CMOS reset and deactivate the Intel default settings.

With these settings I´m no longer experiencing the thermal throttling and power draw and frequency of the CPU  are much more stable.

Thank you very much for your effort and help.

Best Regards

Hi Jehoffy,

Thank you for your update.

We are glad to know that your issue is already resolved by your motherboard manufacturer. For that reason, we will proceed to close the thread. Other community users though can still view how your issue was resolved, so thank you for sharing the fix for your concern.

If you would like to give us an update or if you have further questions, please submit a new question as this thread will no longer being monitored.

Thank you for contacting Intel® and have a great year.

I had the same issue with a z790 gaming x ax board. It is the stupid high voltage requests the Intel default settings request that does this. On spec enhance or perf drive max performance there is 0% throttling and the cpu only requests 1.35v instead of 1.45 Intel default. It's absurd that such a low power drawing chip can not be cooled by a 360mm Aio on stock intel settings. I can draw 245w constantly now with unlimited pl1 and pl2  and not thermal or current throttle at all. Intel really need to fix all their stuff ups.
