NUC6i7KYK Fan Noise

Hey Everyone,

This seems to be a fairly common issue, but I'm experiencing a huge amount of fan noise on my NUC6i7KYK.

I've tried:

  • Updating all software/drivers and restarting
  • Clearing out the fan with compressed air
  • Unscrewing the blower, lifting it gently, and ensuring that no cables are hitting the fan

This began to occur around the same time as I updated the bios, but I'm not certain how soon after the bios upgrade this issue first presented.

I've attached a picture of the board, along with a noise sample taken from the device.

Any advice or suggestions on how to fix this would be wonderful

Re: NUC6i7KYK Fan Noise

Unfortunately, it is not uncommon for the update of the BIOS to cause issues in a NUC's BIOS configuration (including fan speed control programming). In fact, I *always*, *always*, *always* completely reprogram the BIOS configuration after applying a BIOS update. That is, I immediately use F2 to enter BIOS Setup (Visual BIOS) and then F9 to load the BIOS configuration defaults. I then make only the changes to the configuration absolutely necessary for the hardware (boot order, SATA Mode, etc. - and yes, fan speed control programming). Don't forget to save the configuration as you exit Visual BIOS.

I am not a fan of the preset fan speed control programming choices in many of the NUCs, but the KY NUC's is especially poor. Here is my recommended configuration:

Give it a try and see if it helps,

Re: NUC6i7KYK Fan Noise

Thanks for the suggestion Scott. I tried making that change in the bios, but the noise is still there. I also tried switching out both the ram and the hard drive, and the issue is still present. I'm pretty now that it's a hardware issue with the fan.

Re: NUC6i7KYK Fan Noise

Can you make a recording of the noise with the microphone about 1 meter from the NUC? I will be able to tell you whether what you are hearing is "normal" noise for the KY NUCs or something else...

Re: NUC6i7KYK Fan Noise

Actually, after listening to your original recording - and despite it being so close to the unit - I am pretty sure that I am hearing metal rubbing. When I saw this before, it was the result of pressure being placed on the blower while I was inserting the DIMMs. Using a dental pick, I pried up the cowling of the blower and was able to stop the noise from being produced completely. Try this if you can...

Re: NUC6i7KYK Fan Noise

If this doesn't alleviate the noise, your only option then is to either have your place of purchase replace the unit or do an RMA through Intel. Sadly, because the blower has a custom cowling, there is no way to purchase a replacement separately.

If you need to contact Intel for an RMA, here is contact information, sorted by geography:
