Case advice pls

Basically.. I didn’t do enough research to see if the Phanteks GPU mount would fit into the 011 Vision with 140mm fans on the bottom.. after finding this out I have to raise the mobo and now can’t fit 2 120mm fans for exhaust at the back..

I have 3x 140mm reverse blade on bottom 3x 120mm reverse going to be on my nzxt aio And 2 normal for exhaust.. so 6 intake 2 exhaust.

Now being stuck with 1 exhaust how it that going to work..? Any advice?
