I feel you. I was very disappointed with the noise made by my nuc7i5bnh. Did a bit of research and found out that a) the default BIOS fan settings are crap and b) the installed fan is crap as well. Found some recommendations for the fan [1] and BIOS fan settings [2] on the internet and got my NUC completely silent. Perhaps that works for you as well?
