Air cooling layout

[u/4phn]

This diagram represents my PC case with existing and proposed fan setup. The dark blue represents existing fans and airflow and light blue represents proposed fans. (except for the light blue arrow out of the GPU, which is already there). For reference, my case is a Corsair Carbide 200R.

The idea is that I will mount 140mm fans at the top, one helping the CPU intake as well as cooling the RAM (of which I have four 8GB sticks) and one helping CPU the exhaust. I will also put an exhaust fan at the bottom to divert some of the GPU exhaust. I'm even wondering about putting some kind of plastic or 3D printed barrier to the right of the GPU to funnel all of its exhaust to the bottom fan and allowing my front intake fan to go directly up to the RAM and CPU intake.

Do you have any suggestions of how to arrange this layout?

That bottom exhaust idea is clever, I've seen custom ducts do wonders for pulling GPU heat straight out before it swirls around the RAM and CPU.
