12 V 40 mm Ball Bearing Fan
This 40 mm ball bearing fan runs on 12 V DC and fits 3D printers as a compact cooling accessory. It draws 0.06 A at a nominal speed of 6000 RPM and measures 40 x 40 x 10 mm with 3.5 mm mounting holes. Builders looking for a drop-in replacement for small-frame printers will find the dimensions match common 40 mm mounts.
Airflow and Noise Limits
The fan delivers 5.75 CFM (9.77 m³/h) of airflow at a noise level of 24 dBA, which is modest for a 40 mm frame. That output is sufficient for targeted cooling of hotend zones, stepper motors or control boards, but it cannot replace larger case fans or high-static-pressure radiators. Installers needing higher flow or lower noise for enclosed chambers should look elsewhere.
12 V Power Requirement
Operation is specified at 12 V DC only, so the fan must be driven from a 12 V rail or a compatible buck converter. Connecting it directly to a 24 V printer supply without regulation will damage the motor. Verify that your printer’s fan header or controller provides a stable 12 V output before wiring.

Questions about this item
Should I pick the 12 V or a different voltage for my printer?
This fan is rated for 12 V DC only; match it to a 12 V fan header or power supply on your machine.
What does the 5.75 CFM airflow figure mean once the fan is installed?
It moves 5.75 cubic feet of air per minute at 6000 RPM, providing targeted cooling for hot-ends, stepper drivers or small enclosure zones.
Does the 3.5 mm mounting hole pattern fit standard 40 mm fan mounts?
Yes, the 3.5 mm diameter holes on 40 mm centres align with the common 40×40 mm mounting grid used on most printers.
