Hey everyone! I just put together my first PC, and I have a few questions about optimizing the airflow. Currently, I've got 4 fans in total: 2 air intake and 2 exhaust. I'm wondering if I should upgrade the stock fans to something better or larger, and if switching their placement or direction would help with airflow. Also, do you think I need to add more fans? Here are my build specs: Ryzen 5 7600x, 5060ti with 16GB RAM, a B650e motherboard, and I'm using an NZXT H5 FLOW case. Any suggestions would be super helpful!

For optimal airflow, it's typically better to have more intake fans than exhaust. This creates positive pressure, which keeps dust out and helps maintain lower temperatures over time. Since you have a slight negative pressure right now, consider adding an intake fan or removing one of your top exhausts.
Your setup looks solid as is. Adding a bottom intake or adjusting your front fans could improve things a bit, but you probably won’t notice a significant difference with your current configuration.
If you're considering upgrades, I recommend adding bottom intake fans since the H5 Flow is designed for that and can help lower GPU temps. Stick with your stock fans though; they’re decent enough, and while Arctic fans are better, the difference isn't huge. Also, using 5mm spacers for the bottom intakes will reduce fan noise by keeping them slightly elevated from the case.
Before you make any changes, do you have any thermal or noise issues? Bigger fans can definitely move more air or operate more quietly, and more fans generally mean better airflow. But if your current temperatures are good, it might not be worth upgrading.
Thanks for the input! There are no thermal or noise problems; I'm just looking for general advice on fan placement!
Thanks for the tip!
