Fans
Fans BFB03505HHA 5V 0.29A 3-wire 35×35×10mm centrifugal case fan
A pack of twenty 35 × 35 × 10 mm centrifugal case fans running at 5 V and 0.29 A with three-wire connectors
- 5 V operation keeps power draw low at 0.29 A
- 35 × 35 × 10 mm footprint fits tight chassis spaces
- Centrifugal turbine design directs focused airflow through restricted paths
- 3-wire connection enables speed monitoring for thermal control
Pack contents and voltage
This pack contains twenty new centrifugal case fans. Each unit is a 35 mm square turbine-style cooler measuring 10 mm thick. They run on 5 V DC and draw 0.29 A through a three-wire connection.
Target builders
Suitable for integrators populating multiple compact chassis or small-form-factor boards that provide 5 V three-pin headers. Builders who need a different voltage, a PWM control wire or larger frame dimensions should look elsewhere.

Questions about this item
What does the 0.29 A current draw mean for my 5 V header?
The fan pulls 0.29 A at 5 V, so a single standard 5 V fan header rated for 1 A can run up to three of these units safely.
How does the three-wire connection limit speed control?
The third wire provides a tachometer signal only; with no PWM wire the motherboard can only vary voltage, giving coarser speed steps than a four-wire PWM fan.
