Delta PFR0812DHE server cooling fan

The Delta PFR0812DHE is a DC server cooling fan that runs on 12 V and draws 2.54 A. It measures 80 by 80 by 38 mm and uses a 4-wire connection for speed control and monitoring. This unit suits technicians who need a direct replacement for the same model in rackmount or blade enclosures. It is not for builders who want a fan with a different voltage, frame depth or connector layout.

Sustained-load behaviour

Under continuous operation the fan maintains its rated airflow at the specified 12 V and 2.54 A without throttling. The 4-wire interface allows the host system to adjust speed dynamically while keeping thermal performance stable over long periods. It is not for installations that require PWM profiles or voltage ranges outside the factory specification.

Highlights
