70 mm dual-ball CPU fan

The OEM Industries AFB0712HB is a 70 mm axial fan built for compact processor cooling. Its double ball bearing and 4000 RPM rating target builders who need focused airflow in tight chassis. The 12 V, 0.33 A motor connects via a standard three-pin header. This unit suits small-form-factor repairs or upgrades where height is restricted.

Thermals noise and power

At full speed the fan moves air at 4000 RPM with a tolerance of plus ten percent. Acoustic output is specified at 30 dB under normal operation. Electrical draw is 0.33 A at 12 V, equating to roughly four watts. The dual ball bearing is designed to maintain consistent speed and noise levels over extended running periods.

Three-pin control and mounting

A three-pin power connector delivers supply and tachometer signal for motherboard speed monitoring. No PWM wire is present, so voltage-based control is the only option. The package includes the fan unit alone; no heatsink, clips or thermal compound are supplied. Buyers who need a complete cooler assembly or four-pin PWM regulation should look elsewhere.

Questions about this item

How do I install the AFB0712HB cooler and what is the common mistake?

Mount the 70mm fan using the four corner holes, connect the 3-pin power connector to the motherboard CPU fan header, and ensure the 4-pin connector is not forced into a 3-pin socket as the keying differs.

What maintenance will the AFB0712HB need later?

The double ball bearing is rated for long life; periodically clean dust from the 70mm blades and heatsink fins with compressed air to maintain the 30 dB noise level and 4000 RPM speed.

What limit appears first under sustained load?

The 12V 0.33A motor draws fixed power, so the 4000 RPM speed and 30 dB acoustic output are the primary limits; airflow cannot increase beyond the fan's maximum rotational velocity.
