Application
The AVC DBTB0428B2S is engineered for applications requiring the absolute maximum amount of airflow and pressure from a 40×40×28 mm fan. This level of performance is typically employed in high-end server hardware, compact GPU or CPU cooling systems, and situations where extreme thermal density requires aggressive airflow through highly restrictive enclosures. The 4-wire connection facilitates essential PWM speed regulation.
