I have 250 units. About 8 of these randomly turn off for no reason at all. T
What do these 8 miners have in common? are they on the same breaker? switch? rack? when more than 1 miner acts the same it's usually an outside cause.
here are no errors, temps are fine, I tried different psu, different control board, fans are at 97%. If you know what the reason is please let me know. Thank you.
Miners turn-off or reboot for many reasons, heat is the most common, if the miner's temps are fine it could be PSU, if the PSU is dirty or isn't getting enough air flow it i will stop, also if the voltage goes out of the 200-240v range it can trigger protection mode.
The good news is here

All three hash boards are in good shape, finding the complete asic count in the first trial is a good sign.
Since you have 250 of these, I don't think I should be telling you this, but you sure your router/switch can handle all the traffic? that could also be the reason why.
Good point he may not have a good enough set of switches and or router.
