Zyvpee MGT4012ZB-R20 40*20mm 12V 0.22A 3-pin case fan

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.
