50mm 12V Maglev Case Fan

This 50mm case fan operates on 12V DC power with a two-pin connector. It uses maglev bearing technology for quiet running at 4000 RPM. The compact 50 x 50 x 10 mm frame fits small-form-factor enclosures and 3D printer mounts.

Builders needing a slim 50mm 12V replacement

Suitable for anyone replacing a 5010-size fan in tight cases or on printer hot-ends. Not for builds that require PWM speed control, larger airflow volumes, or LED illumination.

Two-pin 12V power connector

The fan draws 0.1 A at 12V for 1.26 W total power. Speed is fixed at 4000 RPM because the two-pin interface cannot accept PWM signals. Verify your header supplies constant 12V before fitting.

Questions about this item

What power connector does the mb50101v2-000c-a99 need from my system?

The fan uses a 2-pin power connector, so your motherboard or controller must provide a matching 2-pin header supplying 12 V DC.

Will the 4000 RPM speed of this 50 mm fan overwhelm older 3-pin headers that expect lower current?

It draws 0.1 A at 1.26 W, well within the capability of legacy 3-pin headers; the 2-pin plug fits the first two pins and runs at full speed without PWM control.

How can I confirm the Sunon MB50101V2-000C-A99 is spinning correctly after installation?

Check the BIOS or fan-monitoring software for a stable reading near 4000 RPM and feel steady airflow from the 50×50×10 mm frame.
