Thank you for contacting Intel Communities.
I was checking this thread and sure you can use this configuration because both Intel® NUCs use the same BIOS, in fact, the processor installed on the Intel® NUC Kit NUC7i7BNH requires more heat dissipation than the one installed on your Intel® NUC, so the fan cooling configuration exceeds the requirements.
You can also check this information posted by N. Scott Pearson that is very informative.
Please let me know if you need further assistance.
I had already posted in the first thread you referenced and was directed by "Alberto R" to post a separate thread. The configuration there does not help - the latest BIOS ignores any changes I make to the settings on this page and continues to run the fan at a constant speed. It doesn't matter what I pick - even "Fanless" - the fan still runs at 3700. The CPU temperature is well below the setpoint and should not be running at all.
I have two other NUCs and the fans in those obeys the settings on the Cooling page. The 7i5BNH did also, until I updated the BIOS. I believe the new BIOS introduced a defect.
Today I was testing this unit and I did not hear the fan running so loud and it run at 2548RPM all the time, the unit seem white but this also depends on the place you have it installed, if you have it on a quiet spot you probably will hear it sound louder but I can see the unit runs pretty quiet.
Perhaps you want to try accessing the BIOS and set the BIOS to default settings, press F9 when you are in the BIOS and then press F10 to save the changes.
I had it set to balance and everything else to default settings and it was quiet.
jonat I understand that you have it set to Quiet and it runs at a constant 3700RPM, I will continue investigating the issue since I can see several users are reporting the same behavior.
In order to further investigate, would you please attach your system information, you can use the Intel SSU (System Support Utility) to get your system information https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility:
Download Intel® System Support Utility
- Download the utility
- Run the exe and select ‘Scan’
- Save and include as an attachment in the Intel Community Forum
Also the DxDiag will be appreciated.
- Click on the “Start Menu” -> Type “DxDiag” -> Press “Enter” -> Wait for the DirectX Diagnostic Tool to finish loading
- In the DirectX Diagnostic Tool, click “Save All Information” -> Save the file DxDiag.txt
- Include DxDiag.txt as an attachment in the Intel Community Forum
Thanks for stepping in. I agree that the fan is quiet, but it should not be running at all when the system is cool and idle on the Quiet setting, and indeed the fan did shut off (or slow down to inaudible) before I updated the BIOS (048 initially, now 049.) Another support rep told me that my only remedy was to get the NUC replaced but I think this is pointless (and means my wife is without her PC for potentially weeks.)
I have attached the files you requested. Please let me know if there's anything else I can do.
Thank you for the information you have kindly attached and we will further investigate this issue related to the fan spinning even at idle.
I am sorry to hear that the newer BIOS (Version 49) is causing you issues. I ran the same update and my system didn’t exhibit any real change.
Could you please try to run a BIOS recovery?
Instructions and downloadable file are available here:
Doing a BIOS restore makes no change - the fan constantly runs. It's interesting that I haven't yet found a Windows utility that will show me the fan speed. I have tried several, including Intel Desktop Utility (which tells me that my NUC is not an Intel motherboard), and none of them show it. The BIOS shows the speed, but that may not relate to speed when Windows is running. I am relying on hearing the fan, which I could not hear with BIOS 45.

Try the following:
- At boot, use F2 to enter BIOS Setup (Visual BIOS).
- Reset the BIOS Configuration by pressing F9 and then Y.
- Make any changes to the BIOS configuration that you absolutely need (boot order, etc.) for your hardware configuration.
- Exit BIOS Setup with a save (you can use F10 and then Y or click on the X and then select Save).
After booting, you *should* (famous last words) see the fan speed control operation return to normal...
The released versions of Intel Desktop Utilities do not run on any of the 5th, 6th or 7th generation NUCs. They were only designed to support Intel's Desktop Board products and only by happenstance did the latest release actually install and work on the 3rd and 4th generation NUCs.
I am working on a capability for temperature, voltage and fan speed monitoring for the BN and AY NUCs. Once I have all of the kinks worked out, I plan to release an appnote that will detail how 3rd-party developers (AIDA64, SpeedFan, HWMonitor, LM-Sensors (for Linux), etc.) can build support into their applications/framework.
With the CPUID HWMonitor you will be able to check fan speed in Windows: DOWNLOADING HWMONITOR_1.32.ZIP | CPUID
HWiNFO64 is an other windows utility which monitors fan speed (see in Sensors in Intel corporation NUC part, CPU raw): https://www.hwinfo.com/download.php . You can download installer version or portable version (no need for installation).

No, sorry Leon, you cannot.
Neither HWMonitor or HWiNFO64 (or SpeedFan or AIDA64, for that matter) has support for the ITE IT8987 eSIO (that's my contraction for a Super I/O IC that has an embedded [micro]controller (EC)) or for the custom firmware (including monitoring and fan speed control) that Intel had developed for this EC for the NUC6CAY and NUC7i#BN NUCs.
If you attempt to use any of these applications, you will see it expose the DTS in the processor and perhaps a few other sensors. It will not, however, expose any of the temperature, voltage or fan speed sensors or the fan speed controller that are implemented within this eSIO.
