Definitative answer on extra fan after upgrading CPU cooler?

I recently purchased a predator 5000 desktop (po5-640-EB11/ RTX3080)


I know many of you have done U9s, u12a/s cpu cooler upgrades and I've seen you re use the old cpu cooler fan on the top but in old threads I'm seeing mixed answers on the top slot and if your using it as intake or exhaust fans - has the community come to a definitive answer on which is best for placement and function(either left, right above the cooler or to the right of the cooler space and then is it better off intaking cooler air or venting hot air out.

    If you look at the PO5-640s case and its fans provisions, there are provisions for 2x extra fans spaces at the top of the PO5-640 case (see below), ideally the front fans and underneath fans suck fresh air into the case and the back and top fans exhaust hot air out.

    The theory and goal of positioning fans in a PC case is to create an airflow channel from the right side/front of your case to the upper left/rear. This channel should bring cool air across the CPU, GPU and other heat sensitive components and then exhaust out of the back and/or top. This path causes the air to heat up as it travels, creating a cycle of cool air in, hot air out.

    here is mine, top fans are exhaust only, when i experimented with them as intake my cpu and gpu temps went up, i have the Noctua NH-U12A dual fan cooler its the largest cooler that will fit our 5000 case, the only thing i have been doing is trying new fans in my case, currently i have all the acer-cooler master stock fans that came with it removed and replaced with be quiet and cooler masters highest velocity argb fans they each make, you can also see i removed the HDD caddy and GPU bracket for better air flow and i havent done proper cable management until i find the fans im keeping lol, im leaning towards the cooler master mobius fans tho since there argb is better than the be quiet light wings and rpms is only 100 difference between them.
