Thank you

Maybe your hashboard temperature detector is damaged that is why it showing no temp.
It is still hashing?

Try run the hashboard first one by one because sometimes if the one hashboard detector is dead it may lead to other hashboard to experience this temperature issue.

Also, post your kernel logs here so that we can analyze the issue as additional info.

Yes but there should be temperature readings from two sources: From the hash board, and from the asic chips themselves. Firmware from around 2017-2018 should be able to report both.

You can also try booting Braiins OS from an sd card to see what it shows. This operation only requires you to use an sd card and move a jumper. Take out the card and move back the jumper and its like nothing ever happened.

Well that's more than normal on S9s , the temp sensor burns real fast and usually no matter what you do to fix it on a software level simply won't work, I simply don't worry too much about it.

as long as the other hash boards show the temp, the temperature on the board that shows no temp is pretty much the same as the other once, it's very seldom to see a wide difference in temps between different boards on the same miner.

but if you can, try a different firmware , maybe you will get lucky.
