I changed my NUC two months ago with a 7i3, I immediately noted that the noise of the fan was a lot more louder then my previous 6i3 (I need to have it in my bedroom), I started to look on the forum and tried different cooling profile inside the bios but without any changes. The strange thing is that, depending on how you move it, changes the loudness of the fan, somethime I fix the noise moving it upside down or on one side, and the fan noise stops. It seems that the fan is not in a stable position, or some wires is touched when the fan is rotating.
Do you have some advice to help me with this issue? Does It make sense for you to try to open it completely two months after the purchase?
Thanks in advance!
If turning your NUC on its side makes a significant difference in the noise level, then either the cooling unit is loose or the blower's bearings are starting to fail. In either case, I would be contacting intel Customer Support (ICS) directly and making arrangements to have this unit replaced. Here are links for obtaining contact information based, upon geography:
