Features and Considerations

The case should offer multiple mounting points for 140mm fans, ensuring that you can create a positive air pressure environment to reduce dust build-up and maintain cool temperatures. The design of the fan mounts also matters; they should be strategically placed to target hotspots effectively.

The best designs channel air smoothly from intake to exhaust, avoiding obstructions that can cause turbulence and noise. The space for cable management also plays a role in airflow; a cluttered case can impede air movement, negating the benefits of using larger fans.

Are 120mm or 140mm fans better?

140mm fans are better for their ability to move more air at a lower RPM, resulting in quieter operation. While 120mm fans are standard and can fit into more compact spaces, 140mm fans are preferred for their efficiency and quieter performance, especially in cases with sufficient space to mount them.
