Is it better to have my AIO radiator fans as an exhaust or intake?

Building my PC this weekend. I want advice though on best way to mount the fans on the AIO cooler. 

 

Case: Meshify 2 Fractal Design

CPU: AMD Ryzen 5950X

CPU cooler: Artic Freezer 2 AIO 360mm cooler

GPU: Will be RTX 3070 until RTX 3080 Ti comes out in January

 

My plan is to have 3x 140mm intake fans on the front of the case and 1x 140mm exhaust fan on the back. 

 

Now the question is whether to have the 360mm radiator fans on the top of the case as intake or exhaust. If intake, the CPU will receive better cooling because it is directly getting cold air, however the GPU will be getting warm air. If exhaust, then the GPU will be getting cold air only but the radiator will be cooled by the warm air created by the GPU.

(Image shows only 2 fans on the front, but apparently it can support 3x 140mm fans including a 360mm top radiator.)

 

Any advice welcome.

Use the top as exhaust. Overall system cooling should be more effective if it isn't relying on a single rear 140mm and positive pressure for exhaust.
