I’m curious about fan setups in PC cases. Is it better for cooling to have all the exhaust fans pushing air out, or do I need some intake as well? If intake is necessary, what’s the ideal ratio? Would something like 50% exhaust to 50% intake be good, or should it be different, like 70-30 or 90-10?

Most setups benefit from positive pressure where you have more intake than exhaust. This helps pull air through filters more effectively. Ideally, aim for an intake-exhaust setup around 50-50, but if you need a preference, lean towards more intake. It could help keep your components cooler.
Best advice is to stick to tried-and-true configurations. If you’re running 6 fans, split them evenly if you can—3 intake, 3 exhaust works well. Just match the numbers as closely as possible for simplicity. That should help you maintain good airflow!
For optimal temperature control, it’s usually best to match your intake and exhaust flow rates. That means if you have a good number of fans, aim for an equal split between intake and exhaust. However, this can vary depending on your specific fan types and placement. Just ensuring that there’s some airflow is crucial.
