Small square black 30mm frame fan with three wires

SXDOOL

SXDOOL AFB0312HA 12V 30mm case fan

SKU CH-AXH2-V6Q0F MPN AFB0312HA

A 30 mm hydraulic-bearing fan delivering 3.5 CFM at 9000 RPM with 25 dB noise for tight-space cooling

  • Delivers 3.5 CFM airflow for compact cooling
  • Hydraulic bearing runs at 25 dB for quiet operation
  • 9000 RPM provides strong static pressure of 0.100 inH2O
  • 3-pin 12 V connection draws only 1.08 W
  • Operates from -10 °C to 70 °C for industrial reliability

30 mm 12 V case fan

The SXDOOL AFB0312HA is a 30 mm square fan designed for tight spaces such as industrial drives or compact PC builds. It runs on 12 VDC and draws 0.15 A through a standard three-pin connector. The hydraulic bearing and tube shaft construction target long service life in continuous operation. Buyers needing higher airflow or larger frame sizes should look elsewhere.

25 dB(A) at 1.08 W

At the rated 9000 RPM the fan produces 25 dB(A) while consuming 1.08 W. Airflow reaches 3.5 CFM (0.099 m³/min) against a static pressure of 0.100 inches of water column (24.9 Pa). The hydraulic bearing helps keep noise steady during normal use. The unit weighs 10.43 g and measures 30×30×10 mm.

Sustained load within -10 °C to 70 °C

The fan is specified for continuous operation across a working temperature range of -10 °C to 70 °C (14 °F to 158 °F). Hydraulic bearing lubrication is rated for extended duty without the rapid wear seen in sleeve designs. Performance figures remain stable at the published 9000 RPM throughout the thermal envelope. Installers requiring PWM speed control or a fourth tachometer wire will need a different model.

Questions about this item

How do I install the 3-pin connector on the AFB0312HA and what step is often missed?

Plug the three leads into a 12 V header matching the pinout; the step often missed is confirming the tachometer wire is seated so the motherboard reads the 9000 RPM signal.

What maintenance will the hydraulic bearing need later?

The hydraulic bearing is sealed and not user-serviceable; plan to replace the fan when noise rises above the rated 25 dB or airflow drops below 3.5 CFM.

At what temperature does the AFB0312HA hit its operating limit first?

The upper working temperature is 70 °C (158 °F); sustained operation beyond that point will trigger the first thermal limit.
