Compact 40 mm Dual-Ball Fan

The Fans DS04010B12U is a 40 mm square case fan with a 10 mm thickness. It runs on 12 V at 0.14 A and spins at 5500 rpm with a double ball bearing rated for 80000 hours. A three-pin motherboard connector with a 10 cm lead provides speed monitoring.

Builders needing a thin 12 V cooler

This fan suits tight enclosures that accept a 40 mm frame and can supply a three-pin header. It is not for systems that require a larger frame, higher static pressure, or a four-pin PWM connector for automatic speed curves.

Airflow range and bearing headroom

The unit moves between 28.17 and 35.97 CFM at a noise reference of 25 dBA. The double ball bearing gives a long service life, but the small frame limits total airflow for high-heat loads.

Questions about this item

What motherboard header does the 3-pin interface on the DS04010B12U require?

The fan uses a standard motherboard 3-pin header; the supplied cable is about 10 cm long.

Will the 12 V 0.14 A rating of this 4010 fan work with a legacy 5 V fan controller?

No, the fan is rated for 12 V operation and draws 0.14 A; a 5 V controller will not supply the correct voltage.

How can I verify the DS04010B12U is running at its specified speed after installation?

The 3-pin connector supports speed monitoring; check the RPM reading in BIOS or fan-control software — it should show around 5500 RPM.
