I had the same case with 2 fans as intake at the bottom(3xitake,1xexhaust) and I think its better for gpu- and cpu-thermals, because the gpu doesnt cover the whole "fan-surface" and so the fans help circulating air. Two things to keep in mind: More fans equals more noice and maybe consider a dustfilter on the bottom.
But my question leans on @Applefreak 's answer: I have now a 2070S Strix in this case and obviously couldn't fit standard fans in the bottom. Are you sure that a NF-A12x15 would fit beneath a 2.7 strix card (inlouding graphicscard sag)? I don't care about noice and would rather put fans back at the bottom than undervolting my gpu. The problem is NOT gpu(sits at max 65 C) but rather CPU-thermals, while gaming. Maybe I need to add that I have a DarkRock4.
Is there anyone else with a simillar configuration?
