SXDOOL DFB402024M 40mm 24V Server Fan

The SXDOOL DFB402024M is a 40mm case fan built for 24V DC operation. It draws 1.9W and connects through a 3-pin hydraulic-bearing assembly. This component targets server and industrial chassis that supply a 24V fan header.

Suited for 24V server bays.

Technicians maintaining rackmount gear or embedded appliances with native 24V cooling circuits will find a direct fit. Builders assembling conventional desktop systems cannot use this fan on typical motherboard headers. Buyers needing variable speed control via PWM should consider other models.

24V DC input voltage decides compatibility

The single specification that determines fit is the 24V DC power requirement. Only enclosures and controllers rated for 24V fan outputs can drive this unit correctly. Verify the header voltage before purchase.

Questions about this item

What mounting holes does the 40 mm frame use?

The fan has a 40 mm square frame with four corner mounting holes for standard M3 screws.

How do I connect the 3-pin plug to a 24 V source?

Insert the 3-pin connector into a 24 V fan header, aligning the keyed notch; the third wire carries the tachometer signal.

When should the hydraulic bearing be replaced?

Replace the fan when the hydraulic bearing becomes noisy or the rotor speed drops below the rated 1.9 W draw.
