Hello Qhorin, thanks for sharing this audio with us, to be honest this is the first time I am able to heard this behavior.
I would like to let you know that I have the same model number and I am not having this situation. So if you want, you can go ahead and replace the unit since it is still under warranty.
However, we know that this issue has been escalated and our engineers are working on this. The situation is that they haven’t been able to replicate.
You would be able to find more information on the following thread. I would recommend you to include your comment on that forum.
Thanks for your answer, the fan finally died.
This morning it wasn't making any sound, and the temps were very high.
The BIOS reported that the fan was running at 0 rpm.
I'll send it back to get an other one.
Thx for your time.
No problem Qhorin.
I know i'm digging up an old thread here, but i just wanted to thank Qhorin for sharing the sound clip.
I've been searching on and off for the past few months for sound clips of a bad intel fan on the usual tech forums and everyone just keeps telling me to check if the cables are in the way.
My fan makes that grinding noise when I shut down the computer. It sounds fine when I start up, and after a while there's a subtle rattling noise that's louder at lower speeds. Thankfully the uncertainty of whether the fan is going to die is over.
Hello Lars5, I’m sorry for the inconvenience you have faced with the NUC.
My recommendation if the product was purchased more than 1 month ago will be to get in touch with our Warranty team in order to replace the NUC http://www.intel.com/p/en_US/support/contactsupport or submit a web ticket at the following URL
