Product identity

The OEM Industries MGA12012HS-O25 is a 120 mm fan-only cooler built around a sleeve bearing motor. It suits builders who need a direct 12 V replacement for a worn or missing case or heatsink fan.

Build integration

The unit draws 0.45 A through a two-wire 12 V lead, so it connects to any standard motherboard or fan-controller header without an adapter. Its 120×120×25 mm footprint fits common mounting holes, leaving clearance for taller memory modules or VRM heatsinks.

Sustained operation

At 2500 RPM the fan moves 98.97 CFM while producing 43.3 dB of noise, figures that hold steady during long sessions because the sleeve bearing maintains consistent speed without PWM ramping. It is not aimed at silent-focused builds or at radiators that demand higher static pressure.

Questions about this item

At 2500 RPM how long before the sleeve bearing becomes the limiting factor?

The sleeve bearing is rated for continuous operation at 2500 RPM with a 10 % speed tolerance, so the limit appears only after extended running time rather than a fixed interval.

What noise and heat output should I expect when the fan runs at 43.3 dB all day?

At full speed the fan produces 43.3 dB and moves 98.97 CFM; the 2 W motor adds minimal heat to the case during all-day use.

Which power header must my motherboard already provide for the 2-wire 12 V 0.45 A connector?

A standard 12 V 2-pin fan header supplying at least 0.45 A is required; no PWM or 4-pin connector is needed.
