Product Identity

The OEM Industries MFC30G-12T is a 30 mm square DC fan designed for compact CPU air cooling assemblies. It operates on a 12 V supply drawing 0.06 A and connects via a standard three-pin power header for speed monitoring.

Suitability

This unit suits builders repairing or assembling small-form-factor coolers where a 3010-size frame fits and low acoustic output around 25 to 30 dBA is required. It is not for systems needing higher static pressure, larger frame dimensions, PWM control via four-pin headers, or integrated lighting effects.

Decisive Specification

The 30 mm by 30 mm frame with three-pin 12 V 0.06 A electrical interface is the single specification that determines fit and electrical compatibility. Verify the cooler mounting holes match the 3010 footprint and that the motherboard header supplies three-pin voltage control before purchase.

Questions about this item

What are the mounting dimensions for the MFC30G-12T fan?

The fan measures 30mm square, matching the SEPA 3010 form factor, so it fits any 30mm mounting pattern with the standard screw spacing for that size.

How do I connect the 3-pin connector and which wire controls speed?

Plug the 3-pin connector into a 12V fan header; the third wire is the tachometer signal, while speed is controlled by varying the voltage on the power pin.

When should I expect to replace the ball-bearing fan?

Ball bearings typically last several years at 2000–2499 rpm; plan replacement if noise rises above the rated 25–30 dBA or if the fan stops spinning.
