I have 2 760 ACX, 1 is the regular one and the 2nd is a Dual BIOS with Backplate. When I got the 2nd card I placed it under the first and went SLi. 1st question, should I have put the DUAL BIOS card first? 2nd thing I noticed is that the 2nd card (DUAL BIOS) sitting below the first card is running 2c hotter than the upper primary card. I have no problems with current games GTA V, Dragon Age, and Witcher 3. Should I leave it alone, switch them? My GPU temps idle at 32c to 35c and peak at 60c, my CPU is watercooled, and it's summer now in Los Angeles. Thanks for the thoughts.
