Was upgrading from a 6th generation i3 Nuc.  Loved the small form but wanted a bit more power and speed.  The old i3 Nuc was very quiet (fan noise hardly noticeable) and I was prepared for a bit more noise based on the reviews for this i7.  But the fan was just going basically non-stop regardless of the cooling setting plus the fan noise was much more noticeable than the i3's fan.  Also the machine just ran incredibly hot even when the only program that is open is Outlook, which probably explains why the fan was going non-stop.  So will stick with my old i3 for the time being.
