I was actually in the same shoes as you but when I saw a few members ran SLI ACX...and said they didn't have temp issues, I went ahead and pulled the trigger
I have a Corsair 500R with the top blocked off due to the H110. There are fans on the top of the case pushing cold air onto the rad but it never makes it to the other side (inside the case). I put my hand under the rad after running aida64 then prime95 for 30mins and I still couldnt feel any wind blowing past the rad. So that part is isolated
I have 2 intake fans in the front of the case, 1 200mm intake fan at the side and 1 140mm exhausting air out the back. Here is a visual representation (minus the 200mm side fan):
so yeah I'm kinda worried about airflow. I mean I could remove all the back pcie case coverings to promote airflow but I'm not sure that will help.
