Compact blower for tight ducting

The Zyvpee BM4515-04W-B49 is a 45 mm square blower fan built around a ball bearing and a 2-pin 12 V 0.18 A motor. Its 45 by 15 mm frame pushes air along the motor axis, making it suitable for small-form-factor enclosures or custom ducts where a radial airflow path is required.

Suits space-constrained builds needing axial exhaust

Installers fitting a miniature industrial chassis, a thin client refresh or a bespoke heatsink shroud can use this non-LED black unit where a conventional frame fan cannot mount. Buyers who need PWM speed control, a larger frame or higher static pressure should look at other models.

2-pin connector fixes voltage-only operation

The two-wire power lead supplies 12 V at 0.18 A with no tachometer or PWM line, so the fan runs at full speed whenever powered. Systems that require motherboard fan headers with speed reporting or variable control cannot use this blower without an external controller.

Questions about this item

How does the 2-pin connector limit speed control on this blower?

The 2-pin design supplies a fixed 12 V feed with no PWM wire, so the fan runs at full 0.18 A continuously unless an external voltage reducer is added.

Will the 45 mm by 15 mm frame fit my NMB 4515 mounting holes?

Yes, the 45 mm square frame and 15 mm thickness match the standard NMB 4515 footprint, using four corner screw holes on 4.5 cm centres.

Which way do I orient the blower so air blows over the heatsink?

The label side is the intake; mount it with the open impeller facing the heatsink so air is pushed through the fins.
