Compact 40 mm Micro Axial Fan

The OEM Industries YM1204PFB1 is a 40 mm square micro axial fan built for confined chassis positions. It runs on 12 V at 0.1 A through a standard two-pin connector. The ball-bearing design supports a speed range of 5500 to 5999 rpm with an acoustic output of 25 to 30 dBA.

Suited for Space-Constrained Cooling Slots

This unit fits builders who need a low-profile 4010 frame to cool small-form-factor boards, embedded appliances or replacement spots in legacy enclosures. It is not for buyers who require higher static pressure, larger frame dimensions or PWM speed control via a four-pin header.

Two-Pin Power Connector Decides Fit

The 2-pin interface supplies fixed-voltage operation without RPM reporting or motherboard-controlled curves. Verify that the target header delivers 12 V and accepts a two-pin plug before ordering.

Questions about this item

How much noise and heat does the 40 mm ball-bearing fan produce when it runs continuously at 5500–5999 rpm?

The fan is rated at 25–30 dBA at its operating speed of 5500–5999 rpm and draws 12 V at 0.1 A, so heat output is minimal for a 40 mm frame.

What power connector must my system provide for this 2-pin 12 V fan?

A standard 2-pin 12 V header is required; the fan uses two wires and a 2-pin connector with no PWM or LED wiring.

Will this 40×10 mm micro axial fan fit the mounting holes on my older 40 mm chassis or heatsink?

It matches the common 40 mm square footprint and 10 mm thickness, so it aligns with legacy 4010 mounting patterns.
