After 5 days of D3 mining, I noticed that sometimes one of boards just turn of (this happens on different D3 devices,not just one), temperatures are ok, boards temps are max 70-71-72-73C. After

If they are really that temp in C, they have probably melted into a puddle!

my boards run as hot at 81c O_O I have the same issue where every couple days the 3rd board will kick off and I have to restart the miner, it's happened twice now

Is that really possible??

Maybe I'm behind times.

Your temps are too high. I found that the D3 has more HW errors running 70c+ and a card will stop hashing then miner has to be reset. To fix this problem I down clocked to 456m and fan at 70% results where 16000 mhs average almost 0 errors and stable hashing no resets needed anymore. I also found you can set miner to 80% fan speed and miner will stay cooler ,but loud. Factory default fan speed control sucks. see below

Factory settings: Frequency (default gh/s 17000) Fan speed: changes depending on temp (not great)

Optimal settings: Frequency (default gh/s 17000) Fan speed: 100% Miner runs cooler ,but very very loud

Medium Settings: Frequency (default gh/s 17000) Fan speed: 80% Miner runs cooler and somewhat loud less errors cooler temp.

Low Settings: Frequency (456M gh/s 16000) Fan speed: 70% not too noisy very stable.

But you void your warranty as you are touching the frequency...
