Is this airflow optimal for my pc?

[SycoSight]

I have a fractal design arc midi r2... And this is a ROUGH drawing of what my system cooling would look like....does it make sense and does the airflow look correct? Two intake fans in the front, one intake on the upper right above the noctua nh 12 cpu cooler, and the power supply would act as the last intake on the bottom left. My gpu would intake cool air that the power supply pushes out and the hot air would be exhausted out the gpu. The noctua cpu cooler would take cool air from the 3 other intake fans and exhaust out the single back fan.

From what I learned, front and sides acts as intake while top and rear acts as exhaust. I would use the top one for exhaust. Most of the time, the power supply should serves as an exhaust, bottom side, taking the air out under your pc if your case allows it. This is what I would do : intake at the front, on the sides if possible. Exhaust on top, bottom and rear. What is your case?
