Compact 5 V Turbo Blower

The SXDOOL BFB0405LA-A is a 40 mm square, 10 mm thick blower fan designed for targeted airflow in tight spaces. It operates on 5 V DC at 0.09 A and connects via a 4-wire, 4-pin header for speed control.

Builders needing a low-profile side-exhaust cooler

This unit suits projects that require a focused airstream across a heatsink or through a narrow duct where a standard axial fan cannot fit. It is not for builds that need high static pressure from a larger frame or a different voltage supply.

4-wire 4-pin PWM interface

The four-pin connector enables motherboard or controller-based speed regulation, which is the single specification that determines whether this blower can be integrated into a given thermal solution.

Questions about this item

How much current does the 5 V blower actually draw once it is running in a system?

The unit is rated at 0.09 A at 5 V, so a typical USB header or 5 V rail will supply that current without issue.

What does the 4-wire 4-pin connector provide for this blower?

The four pins carry power, ground and a PWM control signal, allowing the motherboard or controller to vary the blower speed.

Will the 40 mm by 40 mm by 10 mm frame fit a standard 4010 mounting pattern?

Yes, the 40 mm square footprint and 10 mm thickness match the common 4010 mounting holes used in many compact enclosures.
