I'm trying to figure out the best fan configuration for my PC. Currently, I have three 120mm fans set up as intakes in the front, two 240mm fans at the top (also as intakes), and one 120mm fan at the back acting as an exhaust. I also have a 120mm AIO cooler with its fan configured as an intake. I've heard that having a positive pressure setup is beneficial, but I'm not sure if a single 120mm exhaust fan is sufficient for proper airflow.

Choosing between negative and positive pressure can affect where dust gathers in your case. Generally, it’s best to have front, bottom, and side fans as intakes and the back as exhaust. Top fans can be tricky—too much exhaust might pull air from the intake fans before it circulates around your components. But, having a top exhaust can really help manage GPU temps. Also, consider mounting a fan on both sides of your AIO for better cooling; the extra static pressure might reduce temperatures a bit.
It really depends on the layout of your case. If it's pretty standard, you might want to try flipping the top rear fan to exhaust instead. I saw a video that explained how having both top fans as exhaust can create turbulence that disrupts airflow from the front intakes. So, switching one to exhaust could help with airflow efficiency.
I've always thought heat rises, so I usually set my top fans to exhaust. Currently, I’m running three 120mm intakes on the bottom and three 120s exhausting through my radiator at the top. Plus, my GPU is mounted vertically and exhausts out the side, which helps keep things cool.
