I'm going to get a Corsair 2500x case which supports 9 fans, but i've seen a lot of people saying that 9 is way more than necessary, and that the airflow could be affected. So I wanted to know what is a good amount of fans that looks pretty and is efficient at the same time, and where to put it reversed. I was thinking about getting 6 fans, would it be possible to have a neutral/positive air pressure in this case? It's going to be my first pc build, so I want it to work nicely.
