Ok everyone - long story short - these miners seem to be back to normal with no changes! 
After finding them all out of kilter yesterday and restarting and power cycling a couple times (including one of those times for at least 45 minutes) with the external large fans still running - and still all messed up like described - I just shut it all down until I could see what everyone thought. I didn't want to damage them by leaving them on that way and it was getting late with work coming in the morning.
So, maybe a hiccup with Nicehash? Or they needed to be left off longer to "reset"? I don't know.
But, they came back up running on Nicehash - as usual with all the hash boards and chips back in operation at normal hash rates. I still setup a ViaBTC account and moved my 4 L3+/++ units as well as 4 of my S9's there and currently have the other 4 S9's on ckpool.
I appreciate the effort you guys offered and wish I knew better what happened and why it cleared up. Nicehash seems like a likely candidate from the comments so far with this ending as well - maybe they just fixed their bug?
Crazy!
