Fan arrangement

[Thisbigturtle]

Hello,

 

I am soon going to work on a pc build however only recently found a flaw. 
I have the Corsair spec delta case:https://www.corsair.com/us/en/Categories/Products/Cases/Mid-Tower-ATX-Cases/Carbide-Series-SPEC-DELTA-RGB-Tempered-Glass-Mid-Tower-ATX-Gaming-Case-—-Black/p/CC-9011166-WW

ik it isn’t good for airflow in general however I ran into another issue. My motherboard supports 5 fans whilst my case supports 6 and I don’t want to spend more money on a fan hub. 
 

my question is, what is the best fan arrangement for this situation, 

 

I have a aio liquid cooler for my cpu, the m22 nzkt kraken to be precious and I I want to use that for the single fan exhaust, and three intake fans and leave the top empty, would that be a good idea?

You could just get a fan splitter cable for like $5
