I'm having the same issue reported in this post: http://communities.intel.com/thread/40849 and am wondering what my options are with my DC3217IYE. The BIOS is on the latest version and I've set the System Fan Control to 'Cool'. I've also played around with the fan settings to no avail. The issue tends to happen when I'm streaming video in a web browser. I've also checked for the cabling issue reported in other posts which isn't a problem with mine. In addition, I'm using the HDMI port furthest from the NIC port which I've read can alleviate the heat problem somewhat. The ambient room temperate isn't what I'd class as hot (temperate climate).
Is anyone else experiencing this issue? Am I right to say my NUC is faulty and I should send it back under warranty? Or is this just down to some kind of 'design flaw' and I'll have to live with it? I've seen alternate cases that the NUC can be put in which provide better cooling. Does anyone have any feedback regarding this alternate cases? Do they help the cooling at all? Are there any specific fan settings that anyone can share which actually work?
