SLI running at different fan speeds

  1. Currently using zotac gtx 1080 amp edition in sli.
    Wondering why they are running at such different fan speeds.
    Even when the 2nd gpu hits the temp of the first, it runs much slower.

    When the 2nd one hit 70+ degrees, I set it at 80% fan speed but it only got to 50+% which was about 1200+ rpm.
    I set the fan curve for them to hit 80% at 70+ degrees,

    When both cards are idle, one is at 1000+ rpm and 41 degrees while the other is at 0 and 38 degrees.
    Really new at these things so hope to get some help.
    Thanks in advance!

    Nothing wrong with that. One of the cards gets hotter then the other ,, since their stacked together.
