Description
A CAIZHU 4010 radial blower fan for 12V systems: 40 x 40 mm square, 10 mm thick, with a brushless motor on dual ball bearings. It draws air in through the round intake and pushes a narrow, strong stream out of the side outlet, which is what a 3D printer part cooling duct needs. It comes with a red and black lead of about 30 cm and a white 2-pin 2.54mm plug.

Wiring & getting started
-
Check the fan voltage
Make sure the fan port or supply is 12V. Many current printers, such as the Ender 3 series and Voron builds, run their fans at 24V. On a 24V port this fan needs a step-down converter set to 12V.
-
Fit it to the duct
Push the rectangular outlet into the duct and fix the fan through the corner holes. The moulded arrow on the intake face points to the outlet, and the label side is the back.
-
Plug in and test
Red goes to + and black to 0V. Check which pin of your board’s port is + before plugging in. Set the part cooling fan speed in your slicer or with M106; very low percentages may not start the fan.
