Compact 40mm Case Fan for Tight Builds

This 40 by 40 by 10 millimetre fan fits small chassis, routers or switches where space is limited. It runs on 12 volts at 0.12 amps through a standard three-pin connector. The black frame carries no LEDs, keeping the look neutral for any build.

Suits Low-Profile Cooling.

Builders working on compact cases, network switches or router enclosures will find the dimensions and voltage a direct match. The ball bearing offers reliable operation in continuous-use scenarios. Systems that require high static pressure or large-volume airflow should consider larger alternatives.

Ball Bearing Decides Longevity and Noise

The ball bearing is the single specification that determines service life and acoustic profile in this form factor. It resists wear better than sleeve designs in always-on equipment such as routers. Verify that your device accepts a three-pin 12 volt header before ordering.

Questions about this item

What 3-pin header voltage and current rating does my motherboard or controller need to supply for this R124010DM fan?

The fan is rated for 12 V and draws 0.12 A, so the header must provide 12 V and at least 0.12 A per fan.

Will the 40 mm frame and 10 mm thickness fit the same mounting holes as the 40 mm fan I am replacing in my router?

Yes, the dimensions are 40×40×10 mm, matching the standard 40 mm square mounting pattern used in many routers and switches.

How can I confirm the ball-bearing fan is spinning correctly after I connect the three wires?

Connect the 3-pin connector to a 12 V header, power the system, and verify the fan rotates smoothly; the tachometer wire will report speed to the BIOS or monitoring software.
