I'm putting together a gaming rig with a Lian Li O11 Mini case, a Ryzen 7 9800X3D processor, a 5070 Ti graphics card, and a Noctua NH-U12A cooler. I'm interested in overclocking both the CPU and GPU a bit. I want to set up the cooling with Noctua fans, but I'm looking for tips on optimizing the airflow. Specifically, I'm wondering how many fans and where to place them — should I go for two front intakes, none at the bottom, and one less exhaust? I'd appreciate any recommendations!

For your setup, I'd recommend sticking with two front intake fans and one rear exhaust. This configuration ensures that your components are getting enough cool air while maintaining good airflow throughout the case. If you're looking to enhance it further, you could also consider adding bottom intake fans; they can help push even more air into the GPU area, which is beneficial for cooling during overclocking.
I agree with the suggestion to have two front intakes and one rear exhaust. It’s generally the most effective setup. The bottom intake idea could be great too if you want to direct more air towards your GPU especially during heavy gaming. One exhaust fan is usually sufficient, but ensure it’s positioned correctly to create a good airflow dynamic inside the case.
