Would you mind switching it back to stock firmware the above logs are from BraiinsOS if you can switch it back to the original firmware and run it again maybe the temp issue will show up?
And then post the kernel logs here because I'm a bit confused about the logs from BraiinsOS compared to the original firmware.
Also, I think BraiinsOS still detecting those temp you can only disable it if configure your miner to disable temperature sensor scanning(--no-sensor-scan).
I don't know how to apply it on s17 but try to post on this thread below then ask how to disable the temp sensor scanning.
