My Whatsminer M31S miner fans are running, but HiveOS says they aren't, so the machine mining is suspended. Anyone know how to fix this?

I have been privy to a good bit of HiveOS, a little bit of Foreman.mn, and I have read a little about bixbit/Braiins,etc....

My question is pretty simple, though I'm sure it's an iceberg of an answer.

Is there an objectively superior firmware to be running on my M30S+'s in an immersion tank?

Same question for the OS.

I'm leaning towards HiveOS w/ the Hive firmware, but I'm wondering if I will be able to get away with it. It seems we are currently using Foreman.mn OS and firmware to limit the power consumption of the individual units.
