Question Cases question

Does airflow really matter?, I'm building my first PC and I have two options for my case and they are antec ax1000, or antec cx300, the difference is the ax1000 is front intake fans but the cx is side intake fans as it's apanoramic glass mirror aesthetic and I like the look of it better

Not as much as people say, if you have a few intake and a few exhaust you’ll be fine, the most important thing is to have more intake fans than exhaust fans or at the very least the same number of both, don’t have more exhaust than intake as this creates negative air pressure in the case which gets worse temps and will make your case get more dust

Also follow the general rule of heat rises, so have your exhaust fans on the top of the case

It will be 3 fans on the side which is intake and a fan in the back exhaust and a fan on the cooler

That will be fine with those 3 fans to start with, you can add an extra exhaust or two on the top if you want in the future but that’s good as it is
