When we think about improving our PC’s airflow, the first thing that usually comes to mind is buying more fans, better coolers, or even switching to a completely different case. That’s completely reasonable because your cooling hardware is the most obvious part of the equation. It’s true that better or bigger coolers and fans can help, but you don’t always have to spend money to improve airflow inside your PC. Most of the time, even cheap fans can comfortably move enough fresh air through the case if they’re configured properly.
