Compact 51×25 mm case fan

The Zyvpee BM5125-04W-B40 is a 51 mm square, 25 mm thick case fan built around a ball-bearing motor. It runs on 12 V DC at 0.17 A through a two-pin power connector and carries no lighting. The black frame targets compact enclosures such as projector housings or small-form-factor PCs where a low-profile cooler is required.

Fits tight layouts with two-wire power

Because the fan draws only 0.17 A from a standard 12 V rail, it can be powered directly from a motherboard header or a fan controller without a PWM circuit. The 51×25 mm footprint clears narrow brackets and leaves room for adjacent components, while the ball bearing tolerates varied mounting angles. No additional wiring or adapters are needed beyond the supplied two-pin lead.

Suits space-constrained cooling.

Buyers replacing a projector or slim-chassis fan of the same dimensions will find a direct mechanical match. The two-pin design means speed is voltage-dependent, so systems that require PWM control or higher static pressure should look elsewhere. The absence of RGB or addressable lighting also makes it unsuitable for showcase builds that rely on visual effects.

Questions about this item

What sustained-load limit appears first with the BM5125-04W-B40's ball bearing and 0.17 A draw?

The ball bearing and 0.17 A current set the thermal and electrical ceiling; sustained 12 V operation will hit bearing temperature limits before the motor overloads.

How much noise and heat does the 51×25 mm frame produce when running 12 V all day?

At 0.17 A the fan draws about 2 W, so heat output is low; ball-bearing noise is a steady whisper that stays constant during continuous 12 V use.

Which 12 V two-pin header must my board already have for this 5125 fan to work?

A standard 12 V two-pin fan header on the motherboard or controller is required; the BM5125-04W-B40 plugs directly onto that connector.
