Latest is I've opened a support case with Bitmain on the R4B4... Temp not showing for one of the boards. They're requesting the kernal logs so I'll send them later when I get home and power the R4 on. I was afraid to leave it switched on in case it overheated and I have no visibility into the temp on the 2nd board.
I contacted support about my single board hashing R4 and this is what they sent me back

Dear xxxxxx
Please try one more test to reconfirm the issue. If this does not solve the problem we will pay for the return shipment.
Please upgrade to this version of the firmware:
https://shop.bitmain.com/support.htm?pid=007201612090211421457I07aFFE0609If the upgrade does not complete successfully please upload the Package to Fix Upgrade Failure:
https://shop.bitmain.com/support.htm?pid=007201611260753443104jm60Q6L0639Then please load the firmware again and run the miner for 20 minutes. If this does not solve the issue please send us updated screen prints of the miner overview and the miner status. We will send instructions to ship the machine back to us at our cost.
Regards,
