I honestly don’t get why the new gpu cooler design should be a problem for the cpu temperatures. It’s not like the new design is creating heat energy. If anything the new design is creating less Hotspots at the sidewalls and pcb.Update:
After the release of the new RTX 3x00 FE cards I consider to not make the fliped layout (GPU on top) the default layout. It will be still possible to flip the case to get this orientation. As my test shown the best configuration for overall temps is the side mounted radiator pushing air outside the case. With the GPU on top the radiator will source fresh air over the bottom. This is already not optimal because this intace is limited by the case feet height. New founders cards will also push hot air into the radiator zone. This will made the situation more worse. If the GPU is on bottom the radiator will have more access to much more fresh air through the top panel. Maybe I am worng but I will test it with a RTX 3080 FE.
Btw: For me the new RTX cards are a big step forward and it is something like the 8800 GTX in the past.
so I see it as a much more efficient gpu cooling at the expense of slightly worse cpu temps. but I would still prioritize better air access at the top of the case for the gpu in flipped mode. Especially with a water cooled cpu you will always be more concerned about the air cooled gpu.
i think for the system as a whole the new fe cooler design is a big win.
