I'm going to rebuild my PC in Phanteks P350x and I need some help with where to place my fans. Here are some of my fan setups:

First setup is 2 140mm intake fans in front (Corsair AF140 LED), 2 120mm exhaust on top (Corsair AF 120 LED if I keep the stock fan or Thermaltake Riing 12 LED if I don't keep it) and 1 120mm exhaust fan in the back (stock fan or Thermaltake Riing 12 LED) 

Second setup is 2 140mm intake fans in front (Corsair AF140 LED), 1 120mm exhaust on top back (Corsair AF 120 LED if I keep the stock fan or Thermaltake Riing 12 LED if I don't keep it) and 1 intake fan in top front (Corsair AF 120 LED if I keep the stock fan or Thermaltake Riing 12 LED if I don't keep it) and 1 120mm exhaust fan in the back (stock fan or Thermaltake Riing 12 LED)

 

My question is "Which setup should I choose (or another setup) and should I keep the stock fan and save 10€?"

I'm new here and I think that I posted this in the wrong place. Is it possible to move it?

1st setup is better. 2nd setup will create positive pressure and a lot of turbulence. 

Main system: Ryzen 7 7800X3D / Asus ROG Strix B650E / G.Skill Trident Z5 NEO 32GB 6000Mhz / Powercolor RX 7900 XTX Red Devil/ EVGA 750W GQ / NZXT H5 Flow

The first option is better to prevent turbulence (air just cycling between the top fans) I would make sure your front fans are spinning overall faster than your exhaust fans to help keep airflow either neutral or slightly positive

I'm no expert but I understood that hot air goes up so the top fans should be used for exhaust

While it is true heat naturally rises through convection, it's nowhere near enough to have any when forced mechanically in any given direction

Given the results of this thought experiment, the results of our emperical testing are making a lot more sense.  Convection, while a strong concept in thought, simply does not generate the results necessary to play a discernible role in a typical chassis.
