Compact 12 V blower for tight spaces

The Zyvpee BM5020-04W-B50 is a 50 mm by 20 mm DC blower that runs on 12 V at .24 A. Its two-wire power connector suits builds that need a small, non-LED fan for targeted airflow in confined areas such as slim enclosures or specialised cooling ducts.

Ball-bearing construction with simple wiring

A ball bearing supports the rotor for consistent rotation over long periods. The black frame carries no lighting, keeping the unit visually neutral. Only two wires emerge from the housing, so polarity must be observed during installation and speed control is limited to voltage regulation.

Verify voltage, dimensions

Confirm that your system supplies 12 V DC and can deliver at least .24 A to the fan header. Measure the available mounting area to ensure the 50 mm by 20 mm footprint fits without interference. Check that the two-wire lead matches your board or controller pinout, as no adapter is included.

Questions about this item

What does the 2-wire DC 12 V interface mean for speed control?

The two-wire design supplies constant 12 V power with no PWM or voltage-regulation signal, so the blower runs at full speed whenever it is powered.

Will the 50 mm by 20 mm frame fit my chassis fan slot?

It needs a mounting opening that accepts a 50 mm square frame with 20 mm depth; verify your case or heatsink has matching screw holes and clearance.

How do I connect the two leads correctly?

Match the red wire to 12 V and the black wire to ground on the motherboard header or fan controller; reversing them will prevent the blower from spinning.
