There's long been a debate that the higher you climb in cabinet door perforation percentage, the better your airflow, and in turn, the better your ability to support high-density heat loads (30 kW and beyond). This has helped push the envelope towards 80 percent perforation in some cabinet models. But is it true? Does a higher cabinet perforation of 80 percent really optimize airflow that much better than a closer-to-standard 64 percent cabinet door? Read on to find out.
