Hey everyone, I'm a bit of a noob with PC builds and I've got some questions about the airflow in my Corsair 275R case. Right now, I've got a 240mm liquid cooler (H100X) mounted at the top, a 240mm fan in the front that pulls air in through a mesh, and a 120mm fan at the back that exhausts air. The thing is, when I check the air coming out of the top, it's pretty warm, but the front air feels cool, while the rear air isn't too bad either. I'm starting to wonder if this airflow configuration is correct or if there's something off. My setup includes a Ryzen 9 5950X and an RTX 5070 TI. Is the temperature I feel at the sides normal?

It sounds like you’re set up pretty well! Your current configuration, with intake fans at the front and exhaust at the top and back, is a solid approach. The warm air from the top is expected since it's being pushed out after cooling your CPU. Just make sure to keep your dust filters clean to maintain airflow. If you're really concerned about dust, you might want to consider swapping the rear exhaust for an intake fan. That could create positive pressure, reducing dust buildup while keeping cooling efficient.
You're definitely not alone in thinking about airflow! Having cool air at the front is great, but the warm air from the top is pretty standard especially with your AIO at the top. If you don't mind doing some extra cleaning, your current layout isn't bad at all. If you decide to get more fans, like adding a third one in the front, that could balance things nicely and help manage dust a bit better. Just keep an eye on temps and adjust if needed!
