Cash flow is the quiet constraint behind airflow tuning: the cheapest option is rarely the one that frees the most working capital.

Why airflow tuning matters on the Zen 4

Consistency across batches matters more than peak performance for Zen 4, and airflow tuning is where inconsistency first appears.
