I'm not sure, but I think that the problem is that the fan noise is too high on all NUCs. We expect very low noise when the NUC is idle while Intel are happy with their noise level. Are we supposed to hear the fan when the computer is idle?
We compare this NUC to our laptops and I have never had a laptop witch make so much noise when idle. At idle the NUC noise is what I expect when playing a game.
The bios default to 40% minimum duty cycle. When I change this to 21% the noise goes to an acceptable noise level. My NUC is now running the fan at about 1965 rpm instead of 4000 rpm. Temps are:
cpu: 67(C)
mem: 64(C)
Motherboard: 60(C)
My setup is:
Intel NUC D54250WYK
8 gb ram
Intel Solid-State Drive 530 120gb
No wlan
Win7
All drivers installed
Bios 0022
My NUC sits horisontal on top of a mac mini witch sits on the floor and the mac mini is turned off . The room temperature is about 23C.
