I have the Noctua NH-U12A (https://www.amazon.com/NOCTUA-NH-U12A-Ventilateurs-NF-A12x25-performants/dp/B07PN4RDW3)

I don't know which way the CPU coolers fan should be facing on my motherboard: should the CPU cooler fan be seated so that it is pointed away from the exhaust fans so that it is blowing air away from it? (like the red arrow next to the exhaust fan in this picture?: View: https://i.imgur.com/EL7Gowx.jpg
)

Most of the pictures I have seen show pictures the CPU fan seated so that the blows air from left to right...................... I just want to confirm this is right
 
Bottom (PSU and GPU) is correct. However top side is completely wrong. Fans must suck air from case front side (at right) and blow away through back side (at left). All top side fans in photo must blow in direction from right to left. So turn around CPU fan.

Update: corrected mismatched case sides.

I think you have your lefts and rights mixed up.

In the above pic, air needs to move from right (front of the case) to the left (rear of the case).
Right to left, front to back.
