I'm having some trouble with the airflow in my PC case. It doesn't have any front panels or intake options at the back. Currently, I have three out of four fans set to exhaust and one fan at the bottom as an intake, but I'm not sure if my setup is efficient. Can anyone suggest how I should arrange the airflow direction for my CPU cooler? Also, should I rearrange any of the fans or add another one? Here's a link to my setup: https://imgur.com/a/qcYnL2j

One simple fix could be flipping your PSU around to pull air from outside through the bottom. Plus, consider changing the top front fan to an intake, but think about where you could add another fan if you decide to do that.
Do you have any thermal issues? What are your CPU temps during normal use and under load? Just curious if this is actually affecting performance or not.
Keep an eye on those temps. If they’re high, you might want to swap the top front fan to intake and keep the back and top rear fans as exhaust. Just be aware that top intake can bring in some warm air, so it could be a mixed bag.
If you're not facing thermal issues, then you’re likely fine. Just keep an eye on your temps under load while gaming or doing intense tasks.
