Define R5 airflow setup please ?

[jc.sn]

Case is Fractal Design Refine R5

 

Firstly, I am going to either get 1 more fan at the front along with the stock fan OR replace the stock fan and get 2 extra fans instead.

I am going to get the NZXT x61 kraken too and probably 2 x 140mm fans at the bottom

 

I just want to ask a question about the setup of everything here.

 

SO I'm thinking of doing back exhaust, radiator at the top as exhaust (because the top moduvent don't have a dust filter. I know it's going to be louder than putting the rad at the front because of the noise dampening material but I'm willing to sacrifice noise for performance).

Therefore this leaves me with front intake and bottom intake (the 2 areas with dust filters).

Also airflow or static pressure for the extra 140mm fans ? (if I'm going with this ^ setup, these fans will be 2 at the bottom and either 1 extra one at the front or 2 extra if I replace the stock fan)

 

I will be using :

 

gigabyte gtx 970 g1 gaming

650w power supply 80+ gold coolermaster v650

gigabyte z97x ud5h bk motherboard

intel i5 4690k CPU

 

Thanks !!
