Frequently Asked Questions

Q: Which devices is this 80×80×25mm 12V fan compatible with?

A: This fan is designed for EF06 and EF07 form-factor slots and fits a wide range of 80mm-compatible equipment, including servers, inverters, UPS units, network switches, and DIY electronics enclosures that require a standard 80×80×25mm cooling fan running on 12V DC.

Q: What does the 3rd wire (tachometer wire) do on this cooling fan?

A: The third wire transmits an RPM tachometer signal back to your system's motherboard or fan controller, allowing you to monitor the fan's rotational speed in real time. This is useful for diagnosing cooling performance and receiving alerts if the fan slows down or stops unexpectedly.

Q: How do I install the EF06/EF07 80mm server cooling fan?

A: Installation is straightforward — align the fan with the existing 80×80mm mounting holes in your enclosure, secure it with the appropriate screws (M3 is standard for 80mm fans), and connect the 3-pin connector to your motherboard or fan header. Ensure airflow direction (intake or exhaust) matches your system's cooling design before powering on.
