INTEL NUC BXNUC10I7FNK2 fan noise.

Hi, I just got an INTEL NUC BXNUC10I7FNK2 and i am facing issues with the fan which it seems that it operates without reason at a higher fan speed levels that it should causing a lot of noise. The NUC has been installed with Win 10 6 bit and all the drivers are on the latest possibe firmware including the BIOS (FNCML357.0039.2020.0312.1734 ).

I changed the fan noise profile to 'QUITE' but no results.

Any advise?

Thank you.

In BIOS Setup, change the fan speed control settings to be Fan Off Disabled; Processor: 68c, 20%, 4%; Motherboard: 58%, 20%, 4%.

Did this happen only after you did the BIOS Update?

First thing to try: Disconnect power to the box, wait 5 minutes and then reconnect.

Hi, just uploaded similar question, brand new nuc10i7

https://forums.intel.com/s/question/0D50P00004fv7U5SAI/nuc-10th-i7-high-noise-from-fan-help-needed

 

could you confirm if similar noise / issue observed by you? I think its defective...

Hi guys,

@AFrid3​ I am experience pretty much the same thing with your case.

@svenry & @n.scott.pearson I can not tell if it happens after the Bios upgrade because as soon as i installed the windows i immediately installed all the latest Intel NUC drvers from Intel's Web site. When the NUC is iddle, the noise is up to certain high level which per my understanding it does't sound normal and as soon as i start a certain task (install a program, open a programm) it immediately kicks up higher for a while and then going back to 'normal' which is still too much high for an iddle brand new NUC.

 

I raised a ticket on intel support and i will let you know for any updates.

 

thanks.

Hello!

 

Would these settings you suggest work for NUC105iFNH?

I entered your suggested settings and set also the PL1 Power limit and PL2 Power limit to 20 and 26 respectively. Is this OK or can do damage or seriously hinder operation?

 

Regards,

Matjaz

Also I have observed with these settings you mention my drive temperatures (nvme m.2 and hard drive) have gone up to cca. 46-47 degrees. Maybe it is unrelated, I am not sure.

These settings should work with any of the NUCs. They may not be quite as effective from an acoustic standpoint, but should still be better that Intel's defaults.

My settings do lower the fan speed at lower temperatures over what the defaults would have done (presuming Fan Off is disabled). This could result in slightly higher temperatures near the SSDs. The normal operating range of most M.2 SSDs is 0 - 80c, so high 40's is not going to be a problem.

How do you comment lowering the Pl1 and Pl2 under power settings? I Have gone further down to 15 and 19 respectively with this setting (numbers from tech spec of the processor). I have also set Tau parameter (sustained burst time which is set to 0 by default - that 0 I suspect neans “unlimited”?) to 28 seconds (in tech spec of proc. it said 1 second is hardware default and 28 is recommended setting).
I have wondered why BIOS defaults in pl1 & pl2 are 30 and 64 watts since this is so over the specs for the 10th gen processor. Or am I missing something?

With this setting I see lower temps overall and easyer for the fans to manage temp spikes. Top temps stop at below 90 (usually 87 tops) when working with graphically intensive apps.

I have to add that strangely in bios’s description of the parameter under “Power limit 1 (sustained)” and “Power limit 2 (burst)” it says that values are expressed in seconds. Which doesn’t really make sense here. Also HWiNFO app reports those Power limit1 & 2 values in Watts. So I suspect this is either worded weirdly in BIOS’s description of the parameter, or an error.

@n.scott.pearson​  I just changed the settings and it is much more better right now. I will update the post if anythings changes in the future.

 

thanks
