Compact 40 mm server fan

The SXDOOL MMF-04C24DS is a 40 by 15 mm case fan built for 24 V DC environments such as inverter cabinets, ABB drives or Fanuc server coolers. It draws 0.09 A through a three-pin connector and uses a hydraulic bearing for quiet, long-life operation in black frame finish.

Hydraulic bearing and three-pin lead

The hydraulic bearing reduces friction compared with sleeve designs, extending service life inside vibration-heavy enclosures. The three-wire lead supplies power, ground and a tachometer signal so the host controller can monitor actual fan speed without extra wiring.

Verify 24 V header and 40 mm mount

Confirm your chassis or controller provides a 24 V DC three-pin header; a 12 V header will not spin this fan correctly. Ensure the mounting holes match a 40 mm square pattern and that 15 mm depth clears adjacent components or cable looms.

Questions about this item

How often should the hydraulic bearing be replaced?

Hydraulic bearings are sealed and maintenance-free; the fan runs until the bearing wears out, then the whole unit is replaced.

What thermal limit appears first during continuous 24 V operation?

The 40×15 mm frame reaches its maximum safe surface temperature before the motor hits its current ceiling.

How loud and warm does the fan get after running all day at 24 V?

It emits a steady low hum and the housing becomes noticeably warm to the touch.
