What this product is

The Zyvpee BM5125-04W-B49 T55 is a 12 V DC case fan measuring 51 x 25 mm. It uses a ball bearing and a three-pin power connector, spinning below 1600 RPM for blower-style cooling in compact devices such as projectors or printers.

What to check before ordering

Confirm that your device has a three-pin header supplying 12 V and can accommodate a 51 x 25 mm housing. The fan draws 0.17 A, so the header must support that current. No LED lighting is present, and the connector is not a four-pin PWM type.

Who this suits and who should look elsewhere

Suitable for repair or upgrade projects needing a small 12 V blower with a three-pin connection. Not for builders who require PWM speed control, larger frame sizes, higher airflow, or addressable lighting.

Questions about this item

What comes with the Zyvpee BM5125-04W-B49 T55 fan and do I need a separate cable?

The fan is supplied as a single unit with a 3-pin connector attached; no extra cable is required for a standard 3-pin motherboard header.

Should I pick this 51×25 mm blower or a larger frame for my projector?

Choose this 51×25 mm model when the mounting holes and airflow direction match the original NMB 5125 specification; a larger frame will not fit the same cut-out.

What does the sub-1600 RPM rating mean once the fan is installed?

At full 12 V the blower spins below 1600 RPM, delivering focused airflow through the 0.17 A motor while keeping acoustic levels low for projector or printer cooling.
