What this fan is and who it serves

The OEM Industries 4010M24S NDD is a 40mm square cooling fan that runs on 24V at 0.09A and connects through a 3‑pin header. It is built for tight spaces where a small axial fan can move air across a heatsink or chassis vent. Buyers maintaining compact industrial PCs, embedded boards or legacy server trays will find the 40mm footprint and sleeve bearing a direct fit for existing mountings.

Who should buy it and who should not

This unit suits technicians who need a straight 24V replacement for a 4010‑frame fan and can accept sleeve‑bearing acoustics. It does not suit builders who want PWM speed control, ball‑bearing longevity or an integrated heatsink assembly; those needs require a different mechanical and electrical design.

The specification that decides fit

The 3‑pin power connector and 24V 0.09A rating are the decisive figures: the motherboard or controller must supply 24V on a 3‑pin header, otherwise the fan will not spin or may be damaged.

商品問答

Does the 3-pin connector carry PWM speed control or only voltage regulation?

A 3-pin connector provides voltage-based speed control; it does not carry a separate PWM signal.

What are the physical dimensions for mounting this 40 mm square fan?

The frame is 40 by 40 by 10 mm with mounting holes at the four corners.

How is the fan wired and which lead is often connected incorrectly?

Three wires carry 24 V power, ground and a tachometer signal; reversing the power leads will prevent the fan from spinning.
