Hello, I just bought an Antminer S9, it was running fine for 3 days, decided to change the wire for a better wire since the one I had wasnt really good. I turned it back on now and I saw that one Temp Chip is missing, so basically im doing 9-10THs instead of 14THs... Anyone know why is this happening? Thank you.
Probably a board failed? That happens a lot.
That's most likely the case. Seeing how the Antminer S9 has such high hashboard failure rates it's not really a surprise.
The only thing you can do in this case is accept it or contact Bitmain to RMA it. I'm not sure what Bitmain's policy for hashboard failures is though because I personally haven't had to RMA anything.
You should take into consideration the amount of time it will take to return it and get a new one as well if you decide to do that.
