Compact 40×20 mm case fan

The Zyvpee MGT4012ZB-R20 is a 12 V DC square cooler measuring 40×40×20 mm. It draws 0.22 A through a standard 3-pin connector and uses a dual-ball bearing for reliable rotation. The black, non-LED frame suits builders who need a small airflow source for tight chassis spaces or targeted component cooling.

Airflow capacity and limits

At 40 mm square the fan moves modest air volume suitable for VRM heatsinks, chipset coolers or slim 1U enclosures. The 0.22 A current draw keeps power demand low but also caps static pressure, so it cannot overcome dense radiator fins or high-restriction filters. It is not for builders who need high CFM for overclocked CPUs or multi-GPU thermal loads.

Bearing and connector implications

The 2-ball bearing reduces friction noise and extends service life compared to sleeve alternatives, while the 3-pin header allows voltage-based speed control from any compatible motherboard or fan controller. No PWM wire is present, so automatic duty-cycle curves are not supported. The package includes only the fan unit itself.

Questions about this item

Will the 40*40*20mm size fit my older 40 mm mounting holes?

The fan measures 40*40*20 mm, matching the standard 40 mm square footprint used on legacy cases and heatsinks.

How can I confirm the 2 Ball bearing is spinning correctly after install?

Connect the 3-pin header to 12 V; the fan should start smoothly at 0.22 A draw with no rattling from the dual ball bearings.

Does the package include mounting screws for the 40 mm frame?

The box contains the MGT4012ZB-R20 fan with its 3-pin lead; mounting screws are not included and must be sourced separately.
