The fan permanently high on 4000 rpm NUC8i5BEH

[Adrik]

Hello,

The fan control on my new NUC8i5BEH is not working. The fan is running permanently on 4000 rpm even if CPU cores are idle on temp 30 celsius

I have already tried the "Cooling" settings in BIOS from @n.scott.pearson​ as written in https://community.intel.com/t5/Intel-NUCs/NUC8i7BEH-high-fan-noise/td-p/644343. 

Even the setting for "Fixed" did not change the fan speed.

Running the Prime95 put my CPU on 70 celsius, but the fan speed did not change. 

Accordingly Intel Driver and Support Assistant I have newest drivers and BIOS version (v. 83)

Is my new NUC fan control broken? The fan running on 4000 rpm is very noisy.

Any advice?

I'd check the physical connection also to see if it's plugged in correctly, if the sense wire has a broken connection it could also affect the fans like this.

Hi @Adrik 

1. Similar problem was reported in this thread. Could be you got one of this faulty NUC? Just joking. Any way, I suggest you that you open ticket to replace your NUC (even better to replace it in the store you have bought it).

2. Is your NUC a new one and this problem exists from first use, or it happened later. If this problem started after some time of use, what event proceeded the failure?

Hi @LeonWaksman 

thank you for the thread link, it looks like I have the same problem as written there. 

Yesterday I have recovered BIOS with v83 with no success.

It looks like my unit and the unit from @fan-man were produced on same day

I will return my unit and go for the new one or try NUC8i5BEK2 as an alternative.

Thanks

Hi,

forget to mention, that I have a new unit bought 3 days ago and the problem exists from first use. My unit was produced on 06/2020 and came with BIOS v83 already installed

Hi Adrik,

Are you aware that NUC8i5BEK2 is the "low" NUC (i.e. there is no place for 2.5" SATA drive and you have only M.2 slot on the board). So, why you are not trying other NUC8i5BEH ?

Hi @LeonWaksman 

thanks for the info. I ordered the new NUC8i5BEH now, try another supplier.

Thanks

Hello,

today I have received the new unit NUC8i5BEH, but it has the same problem. Fan permanently on ~ 3700 rpm.

Both units are produced on 06/2020. 

Somebody with new ideas?

Thanks

Same here.

Bought a NUC8i5BEK on amazon (europe).
Date of Manufacture: 03JUN2020

Fan constantly running at 3830 rpm!
It doesn't matter what fan profile I use, always the same result.

Really sad, this is my 1st NUC, I'll send it back....

Hi Alberto,

unfortunately, both units of NUC I have purchased in Europe were broken (produced 06/2020), I have sent them back. It looks for me that the quality assurance for NUC production at Intel does not exist.

This was my first experience witch NUC and probably my last.

Regards,

Adrik

P.S The case could be closed
