NUC7i7DNBE - CPU core Thermal Throttling temperature limit

Jump to solution

Hi,

what is default CPU core Thermal Throttling temperature for NUC7i7DNBE? (The temperature threshold where CPU starts lowering it's frequency to try to stay below this temperature limit)

I see OEMs usually have different limits in their systems. (85 - 100 C)

Can we adjust this temperature limit in BIOS or software on Intel NUCs?

Thanks for your answer.

Hello tom_rob,

Thank you for joining this Intel Community.

Intel® NUC Board NUC7i7DNBE supports the Intel® Core™ i7-8650U Processor. According to https://ark.intel.com/ https://ark.intel.com/, the Tjunction (i.e the maximum temperature the cores can reach before thermal throttling activates) for this processor is 100°C. It is worth mentioning that the processor may exceed the Tjunction briefly without being considered overheating.

Now, it is not possible to change the Tjunction from BIOS since throttle temperature can vary by processor and BIOS settings. If you unit experiences high temperatures, you can follow these steps to troubleshoot this issue.

1. Load default BIOS settings.

 

2. Keep your unit up to date (Update BIOS if needed)

 

3. Change the Fan Control Mode in BIOS.

Thanks for your answer, it helped.

So manufacturers can customize this CPU thermal throttling temperature in their systems (since it can vary between OEMs with the same cpu), but it is not something available to end user. Right?

Hello tom_rob,

 

 

I am glad to hear that you found the information provided helpful.

Yes, this is correct. System manufacturers can customize it depending on the platform/product they will be developing.

 

 

Now, keep in mind that this information may not be available publicly in order to prevent system conflicts. However, you may need to contact the system manufacturer to get additional information about it.
