Not reading temp on 2nd AMD GPU

[camaro1919]

I just upgraded GPU cards on my computers.  I had a single GTX 760 card in each of two computers.  Currently I have both GTX 760 cards in one box and two new RX 580 cards in the other box.  In the one box, TT 7.52 sees both GTX 760 cards fine but the other box (TT 7.52 & 7.72) only sees one RX 580 card.  Other programs such as Afterburner and GPU-Z see both AMD cards.  The computers are mostly used for BOINC crunching.
Any ideas?
Thanks.

Update
I read in other posts that sometime there are issues with motherboards.  The MB (Z87-A) I put these cards in is fairly old (~7 y).  I have another computer that is only about 2 years old (Prime Z270-A).  I plan to try the dual RX 580's in there to see if it makes a difference.  I just need to run out my BOINC GPU work units first.

TThrottle uses the AMD driver and that doesn't always work.
TThrottle can use HWiNFO or GPU-Z that read the temperature in another way.

Thanks for the reply. 
I am using GPU-Z to get the temp reading for the 2nd AMD GPU.
