yup i wanted to do exhaust for both the bottom fans, but the one below motherboard is interfered just very slightly by the 8-pin CPU power connector due to layout of my motherboard. so had to flip it around, and wanted other side to match. so far so good and gaming at 1080p 240Hz fine with CPU and GPU temps always below 70 and 80 degC respectively. if it gets out of control some day i will flip the fans again to see the difference.
so far so good for me with the fans intaking from the bottom and blowing upwards, guess the convection from hot air rising up kinda helps in a way? the top of the case feels hotter than any other builds i had in the A4 previously, but components are all cool, so i suppose we are all good.
didn't have to remove the backplate, it fits nicely without, unlike EVGA 30xx XC3 Ultra (not Black) cards where the backplate interferes because they are really thicker than 40mm overall. i had to loosen the frame screws at the back of the GPU in order to fit it is, exactly as dan mentioned for GPUs longer than 293mm.
Corsair SF750 Platinum, actually i heard 3070 Ti draws way more than 3070 for the performance gap it has compared to 3080, due to the use of GDDR6X and the fully activated GA104 chip with 3072 cores and 6144 shaders.
thanks more to the genius who came up with this case and leading the movement towards sandwich layout.
