purchased a new nuc7i7bnh for a small workstation roughly 2 weeks ago. upon getting windows 10 pro installed and several apps setup (dropbox, quickbooks, etc) i had my first system lock up. no blue screen or error message... just frozen. traditionally, this is from some sort of hardware issue, so i started checking with some basic tests... memtest86, intel processor diagnostic, crystalmark... memtest took the longest (almost 5 days for 16gb of ram - but thats about average) - but everything passed without issue. my gut told me that even though the memory passed all tests, it was acting like a memory issue.... anytime i would put a heavy read/write action in place (ie: first setup of dropbox which had about 500k files worth about 160gb) i would experience a lock up.
so i had the memory exchanged under warranty. 20 minutes after install.... same thing again. so i swapped out the only other item i could in the machine, the pcie ssd - still resulted in the same thing.
then i noticed - anytime i was putting this system under load, i would hear the blower kick in heavy. so i installed hwmonitor and kept it on top for anything i was doing. sure enough... every single time that system reached 100 deg c, that system would lock up. on this very forum in several places, intel reps have stated the system is designed for 100 degrees or lower. however, inside intel processor diagnostics it very clearly states for the cpu a max temp of 90 degrees cel.
i updated bios to the latest (released just a week or two ago it appears) which made no difference.
i have turned off turbo on the processor, and cranked the blower up WAY high (what i have set it to is attached in the images below). at this point, that seems to be doing the trick, but makes it so damn loud it somewhat defeats the purpose of having a tiny machine. and im not 100% sure just yet... still testing. but its definitely at least more stable at this point.
i purchased two identical nuc's... the other one is not having the system lock ups like this one, but is running just about as hot. so im not sure what is going on - but there is obviously an issue. any ideas?
