How are SLI/NVLink people getting on? I received a second Founders today and the top card is stuck at 85/86 with the fans blaring at 90% during a game of Black Ops, every setting is stock. My case is a 900D with good airflow but the top FE seems incapable of keeping itself cool under load, which begs the question 'Why can't the FE keep itself cool?'.
Running two 2080 Ti FE cards in SLI (1 slot spacing) using the phanteks evolv flow edition. If using one card only without the second installed the card averaged about 75c with 55% fan speed even under full load, card never broke past 79c or the fan never went passed 59% when I gamed on it pretty heavily for a week at 4K with game settings pretty much maxed out.
Using both in SLI the top card will hit in the worst case scenario 85c but usually averages about 83c while the fan is at auto speeds and pretty much sticks to 65% 90% of the time. Bottom card at it's hottest may hit around 74c and 55% fan speed but usually hovers around 70c.
GPU clocks will usually auto boost to 1840Mhz stay around that most of the time, does fluctuate though so can jump between 1710Mhz and 1840Mhz depending on the game and the load on the GPU's. Both cards from idle will boost from 1940Mhz but clock down pretty quick.
If gaming in Destiny 2 at 4K all settings maxed both cards will run between 1810Mhz to 1890Mhz with the above temps but two cards running this game is effortless and both cards are at only about 55% to 65% load usually.
All games I run are VSYNC capped to 60fps.
