Fractal Node 804 Radiator Position?

[Pcexbird]

The fractal node 804 allows 4 different positions for radiators. As you probably know the 804 dual chambered design where the PSU and HDDs are in a second chamber. I'm trying to decide whether to mount my radiator on the PSU side front (but only 1/3 of the front has immediate access to open air for intake) Or I may possibly put the radiator on the GPU CPU side in exhaust position at the top. I do worry about temps by putting it in the CPU side especially because my CPU would be absorbing a lot of heat from my GPU in the same chamber. 

 

Would it be advisable to put the radiator as an intake on the non gpu/cpu side at the front of my case even though it has limited access to fresh air in the front of the case? Or would you put it as exhaust and risk CPU temp increases. 

 

The top of the case is open air vented from front to back unlike the front which as you can see it gets air...and I have good SP fans in position so airflow idls still optimal in front but moreso at top.

 

You're probably wondering why I don't install it in the coolest position (non gpu side top exhaust position) I cannot because that's where all the hard drive cages are. Unlike the pics the front side of my case will implement all spots totalling 4x120mm fans in front not 1 like pictured.

I've attached some pics to visualize optimal positioning of the 240mm rad and 2x120 fans.

Any and all help is appreciated.
