How Many Fans Do I Need?

We Recommend 3 Air Changes per Minute
Every fan has a CFM rating - that’s the volume of air it moves per minute. A higher CFM means faster ventilation. But keep in mind, manufacturer ratings are measured under near-perfect conditions: no heat load, no restrictions, zero static pressure. In the real world, actual performance is always lower.
Inside your cabinet, airflow is influenced by the number of components, the heat they generate, and how freely air can move in and out. That’s why our calculator aims for roughly three complete air changes per minute. This ensures reliable cooling for most AV and electronics cabinets.
Tip: If your cabinet is tightly packed, poorly vented, or located in a warm room, step up to the next fan size or add an extra exhaust unit for peace of mind.
