Build Advice Intake or Exhaust on top?

[Seksullah]

Hey guys. I bought a pair of corsair fans for my radiator and i want to use one fan that came with it. Should i install it on #1 location ~4-5 centimeters behind that intake fan or should i install it on #2 as exhaust/intake? The fan i will install is the same with that green one on the drawing. I gave the fan's specs so we can do maths

My case looks pretty much like this: https://prnt.sc/njmrp3

TOP = Exhaust

Should i use it as a exhaust or an intake?

Exhaust.

Your picture shows you would probably have a negative pressure if you only have a single intake fan in the front. If that is true, I would put that as an intake to provide airflow around the CPU. The front intake will provide air for the graphic card exhaust.

yes thats also my concern but i dont have extra room to install it to the front side. i can only install it to the top or behind the front intake

Nature makes hot air go up, if u do otherwise you are fighting nature and makes your airflow inefficient (takes more effort to move hot air downwards).

With the exhaust from the radiator right behind, you would get a flow from the top to back that is pretty direct. I think you will have limited airflow if both the radiator and the top are exhaust, because they won't have any source air to move.

and i guess the top "exhaust" fan can redirect the air to itself so there will be less airflow on the radiator which can cause less cooling
