  • Delta brand engineering ensures reliable long-term operation

Purpose and audience

The SXDOOL BSB05505HP is a 5 V DC case fan drawing 0.40 A through a four-pin connector. It is built for chassis or devices that provide a 5 V header and need a compact cooling component.

Fit and limits

This unit suits builds with a 5 V four-pin header and modest airflow needs. It does not suit systems that only supply higher-voltage headers, boards limited to three-pin voltage control, or configurations requiring greater airflow or different mounting dimensions.

Highlights

  • 5 V low-voltage operation keeps power draw minimal
  • 40 A current rating delivers efficient cooling performance
  • 4-pin PWM connector enables precise speed control
  • Delta brand engineering ensures reliable long-term operation

Questions about this item

What motherboard header matches the 4-pin power connector on the BSB05505HP?

The fan uses a standard 4-pin PWM header, so it plugs directly into any 4-pin CPU or chassis fan header on the motherboard.

Which orientation should the notch on the 4-pin connector face when installing the BSB05505HP?

Align the notch with the missing pin on the header; the connector only seats one way, so do not force it if it resists.
