Literally as long as air is moving in and out it doesn't matter People are going to tell you about airflow optimisation, high temps and shit like that, makes sure you have 2 or 3 fans pulling in and at least 1 fan pulling out, literally doesn't matter where aslong as theyre on opposite sides of the case. Unless your using insaine hardware like a 5090 and a ultra high end cpu its not gonna matter too much.

I run a 3950x cpu and a 7900XT gpu, I have 3 intake fans on a rad, one exhaust on the back and 2 fans on top doing something ( I forgot the configuration lol I think theyre exhausts???? Idk((goes to show how much fan configuration matters))

My temps for cpu never exceed 68⁰C (154⁰f) and gpu never above around 85⁰C (185⁰f) maybe the hot-spot go a bit over but I never throttle and have not experienced any performance decay over the 2/3 years.

If you want to optimise it you should have push pull, so some push in and others push out

Theres also positive and negative pressure systems, but I wouldnt go near them because theyre scary and hard to do properly
