Need Rad advice

[Focus182]

Hi i was wondering if anyone could help me decide on what to do with my water cooling setup.

I currently have the NZXT Noctis 450 case with a EK 360mm PE rad in the top of my case and a EK 120mm PE rad in the back with three fans in the front. 
I was thinking of getting rid of the 120mm at the back and putting in a 360mm of the same type at the front instead so i'd have dual 360mm's (120mm has to go because of space in this scenario and only a slim fan could possibly fit there)
But i'm wondering if this would be beneficial at all seeing as i'd either be blowing warm radiator air through my case and into the second radiator or if i set both rads as exhaust or intake that i'd either be starving the fans of air or throwing all the rad heat into my case. 

If i could get any advice that'd be great

Thanks.

Don't worry about the warm air. it's only warmer by like 1c, so the second radiator will work fine.

Rad exhaust is not very warm since the heat is so spread out. Although I would recommend leaving the 120mm rad's fan in the back of the case.

Right ok, so i should be all fine with intake through the front rad and exhaust out the back then? And yeah i would leave the 120mm rads fan at the back but the top rad will block me slightly. A 15mm fan would fit there though.

You will definetly get better temps with a 2nd 360. I would recommend trying all rad fans as intake and only the rear as exhaust. It depends on the case, but some do benefit from this airflow.
