Frequently Asked Questions

Q: What systems is the AFB0312HA 30mm cooling fan compatible with?

A: The AFB0312HA is designed for use as a CPU fan replacement, server fan, or chassis cooling fan in any system that uses a 30×30×10mm 12V fan with a 3-pin connector. It fits many small form-factor PCs, server blades, network switches, and other electronics that require compact 30mm fans.

Q: Does this cooling fan support speed monitoring?

A: Yes. The AFB0312HA uses a 3-pin connector that includes a tachometer (RPM signal) wire, allowing your motherboard or controller to monitor fan speed in real time through your system's BIOS or fan control software.

Q: What type of bearing does this fan use and why does it matter?

A: This fan uses a double ball bearing, which offers longer operational life, better performance at higher temperatures, and lower noise over time compared to sleeve bearings. It's the preferred choice for server and 24/7 environments.

Q: How do I install the AFB0312HA replacement fan?

A: Power off and unplug your system before installation. Remove the old 30mm fan, align the new AFB0312HA fan with the mounting holes (ensuring correct airflow direction), secure it with the appropriate screws, and connect the 3-pin connector to the corresponding fan header on your motherboard or controller.
