80 mm 12 V 3-Pin Server Fan

This 80 mm square fan from OEM Industries runs on 12 V and draws 2.4 W through a three-pin connector. It is built for server and workstation chassis that need a compact airflow device. The ball bearing and 8025 frame suit continuous duty in rack environments. Buyers who require PWM speed control or a four-pin header will need a different model.

Three-Pin Voltage Control Limits

The three-pin interface adjusts speed by varying voltage rather than a PWM signal. Motherboard headers that only supply a fixed 12 V line will run the fan at full speed constantly. Headers without monitoring pins cannot report rpm back to the system. Builders who need closed-loop speed curves or software fan profiles should verify header capabilities first.

Clearance and Header Check Before Ordering

Measure the mounting holes to confirm an 80 mm by 80 mm square footprint with 25 mm thickness fits your heatsink or case opening. Ensure the board or fan controller provides a standard three-pin 12 V header with the correct pinout. Systems that only offer four-pin PWM headers or proprietary connectors will not mate without an adapter.

Questions about this item

Should I choose the 80 mm version or a larger fan for my server CPU cooler?

This model is an 80 mm square fan with a 25 mm thickness, designed as a direct replacement for 8025 form-factor server coolers.

What does the 2.4 W rating mean once the fan is installed in a real machine?

At 12 V the fan draws 2.4 W, which translates to modest airflow for compact 1U or 2U server chassis without overloading the header.

How does the 3-pin connector limit speed control in practice?

The 3-pin header supplies fixed 12 V power; speed varies only with voltage changes, so PWM control is not available on this unit.
