I get the new firmware "A1246-A3201-Plus-P3600W-New-Temp65_21071301" from canaan.
Same temp problem, and with it, it can't go up to 73 TH in turbo mode
here are the temp from log

1st, it's nice that Canaan is still using temp sensors in each chip

Seeing that leads to tables tells me that either those specific chips have faulty sensors or the chips/cores themselves have issues. Either way, assuming the miner is happy running in normal mode that's how I'd run it and not bother with repair because of the time involved.

Query: In normal mode I take it those chips are still reading higher temps that the others?

That said, I'd 1st see what Canaan has to say about it. With the Avalons at least the end user can actually replace bad hash boards themselves if they are comfortable doing it.
