Fans EFB1512HHG S12N 12V 3.20A 3-wire case fan

SKU CH-RSAM-V8T29

12 V server cooling fan drawing 3.20 A via a 3-wire connection

  • High airflow for demanding server cooling
  • 12 V DC input matches standard power supplies
  • 20 A current rating supports high-performance operation
  • 3-wire connection enables speed monitoring

High-current 12V server fan

The Fans EFB1512HHG S12N is a 12 V DC case fan rated at 3.20 A. It is built for servers and workstations that need strong airflow from a standard three-wire connection. Buyers who want PWM speed control or a four-pin header will not be served by this model.

Three-wire voltage regulation limit

The three-wire interface adjusts speed by varying voltage rather than by a PWM signal. This means the motherboard or fan controller must support voltage-based regulation for the fan to change speed. Systems that only provide a fixed 12 V line will run the fan at full speed continuously.

Highlights

  • High airflow for demanding server cooling
  • 12 V DC input matches standard power supplies
  • 20 A current rating supports high-performance operation
  • 3-wire connection enables speed monitoring

Questions about this item

Should I pick the 12 V 3.20 A version or a lower-current model?

The 12 V 3.20 A rating matches the EFB1512HHG S12N specification; choose it when your server chassis or power supply is designed for that exact current draw.

What does the 3.20 A current mean for cooling performance inside a server?

It indicates the fan can draw up to 3.20 A at 12 V, delivering the high airflow needed for dense server environments while reporting speed via the third wire.
