    Disabled SLI, ran the same stress test (Time Spy Extreme full loop, ~20 minutes) but now only on master card only (with slave still inside), max fans, 23C ambient: card was constantly on full blast, full turbo clock all the time (stable 1911MHz), was drawing ~155W (with peaks to 170W) and... it stabilized at 63C! Freaking 27C lower compared to enabled SLI!
    It doesn't look like contact issue, unnecessary shim or wrong sized pads - it looks like great temp with a great cooling solution. Amazing temp, exactly the same as when I had only single 1080. But then with SLI on - it all craps.

    So VC is working, maybe. I`m even more confused now.

    Well it is double the thermal load so it puts the cooler under a lot more work.

    My SLI setup wouldn't go past 70 ever at full load on Wticher 3 - there is something more to this

    I was using stock voltage.
    No flashed Vbios.
    both cards clocked at between 600-700 memory and +175 on core giving me 2088 boost.

    in 4k on witcher after around 3 hours , both cards would sit max around 63-65

    That's a very healthy core clock :)

    Thanks bro - stresstech told me my 1080's in the laptop were hand picked from over 28 samples.

    It does make it a little unfair to do a comparison against regular cards. Though normally a well fit heatsink should maintain 2ghz clocks without throttle.

    Actually, the OP @artpra purchased one of my 2 1080's, so I am giving him the cards performance when it was in my machine.
    But yes i get your point.
