This is interesting. So I got the middle board identified as the error. the log is below.
I did do a hard reset this morning, and was still having the issue. I did it again after identifying the board and now now it works.
Error log with just the middle board running:
~snip~
What do you mean it works?
Is the issue solved after a hard reset? Is all the hash board running?
Or did you just run only two hash boards and remove the middle board?
If the middle hash board is the culprit having over temp issue there might be one ASIC chip with a loose heatsink it needs to reattach but the problem you will need test fixture to test which chip is overheating.
Anyway, if you want to repair it with your own there is a guide that you can follow but I'm sure it needs some repairing tools. Check this link below
