According to partial logs above it seems that the fan is set at low speed "FAN PWM: 40" and it seems that the miner is overheating that's why it shows abnormal temp I guess.
I don't think so, no where in the kernel log where it mentions anything about overheating, it isn't possible because the miner only starts mining after this stage
Whatever happens before is just testing the temp-sensors to see if they are reporting valid readings, the temps in the kernel log imply that the sensor readings aren't accurate and that's due to a bad PSU or dead Asics on certain hashboards, but without seeing the complete kernel log and all the other details we requested, all we can do is speculate.
