Fans BSB05505HP 5V .40A 5.5CM 5008 4-wire case fan

SKU CH-AZ4P-BS8S5

A 5.5 cm, 4-wire case fan running at 5 V and 0.40 A for PWM speed control

  • 5 V operation keeps power draw low at 0.40 A
  • 5 cm frame fits tight chassis spaces
  • 5008 motor design drives quiet airflow
  • 4-wire PWM header enables precise speed control

5 V 4-wire case fan

This 5.5 cm case fan carries the model code BSB05505HP and runs on a 5 V supply drawing .40 A. The 4-wire connection supports PWM speed control so the system can adjust fan RPM to match thermal load. Its 5008 frame size fits compact chassis where space for cooling is limited.

Builders needing a small 5 V PWM fan

The 5 V rating means this unit suits boards or controllers that provide a 5 V fan header. It will not suit builds that require a larger diameter or higher airflow than a 5.5 cm frame can deliver. Users without a 5 V header should look at alternative voltage options.

Questions about this item

How do I install the BSB05505HP 4-wire fan and which step is often missed?

Mount the 5.5 cm frame with four screws, then connect the 4-wire PWM plug to a 5 V motherboard header; the step often missed is seating the connector fully so the tachometer signal works.

What maintenance will the BSB05505HP 5008 fan need later?

Use compressed air to clear dust from the blades and rotor every few months; if bearing noise appears, replace the whole unit as the motor is not serviceable.
