Hi,
I have been running my rig with 4x powercolor rx 580 8gb, 2x rx 570 4gb and 1 sapphire rx 580 nitro + 8gb

after updating to this blockchain driver one of powercolor rx 580 card started to heat up very much. +5 degrees than others. I tried to run only with this card. same heat. reverted back to previous driver but heat still goes up to 75+ degrees. 4 cards are identical and only one of them causing this issue.

What do you guys think might cause the problem?
