Exactly what mine was doing, aside from the being on a different board.  I had board 1 with temp and none of the others.

Is your machine also blinking and beeping at you?... I see it's not hashing like mine.

I sent them an email, and after realizing i'm only getting 1 reply back a day, i entered a ticket also on their "support center", it has gone unanswered so far.

In the meantime, my other miner is also showing up all 0s for the temp reading, so i'm no messing with it yet, until i get more feedback from the one that's currently shut down.  In order to prevent any further damage, but i'm wondering if i need to send both back at this point.

Please let me know if you hear anything and i'll do the same
