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.

4010 blower fan, 12V

With its lead and white 2-pin plug fitted. Mounting screws are not included.

Great for

Cooling printed layers through a part cooling duct on a 12V 3D printer
Replacing a worn or noisy 12V 4010 blower
Blowing air across a heatsink or driver board in a small 12V enclosure
Pushing air through a narrow printed duct in a 12V project

Wiring & getting started

  1. 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.

  2. 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.

  3. 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.

Frequently Asked Questions

Answers to the questions buyers ask most.

Will it plug into my 3D printer board?
Usually, yes. It ends in a white 2-pin 2.54mm XH-style plug, the plug used on most printer board fan ports. Before plugging in, check that the port supplies 12V and which pin is +. Red is + and black is 0V.
Will it work on a 24V printer?
Not directly. This is a 12V fan, and on a 24V fan port it would run over voltage and fail early. Many current printers, including the Ender 3 series and Voron builds, run their fans at 24V. Use a 24V 4010 blower there, or feed this fan through a step-down converter set to 12V. The voltage is usually printed on the old fan's label.
What is the difference between a blower and an axial 4010 fan?
A blower like this one pulls air in through its round intake and pushes it out sideways through a narrow outlet, with enough pressure to drive air through a duct and nozzle. An axial 4010 fan blows straight through its frame, moving air over a wider area at lower pressure, which suits heatsink cooling. Part cooling ducts are designed for blowers.
Which way does the air go?
In through the round intake on the blade side and out of the rectangular side outlet. The moulded arrow on the intake face points towards the outlet. The side with the round label is the back of the fan.
What screws fit the mounting holes?
The four holes are about 2.4 mm across and about 35 mm apart, about 2.5 mm in from each edge. M2 screws pass through them, and M2.5 self-tapping screws will cut their own thread. Do not force M3 screws. The datasheet has a dimensioned drawing.
Can I control the speed?
Yes. A printer board's PWM fan output sets the speed from your slicer or with M106. Very low percentages may not be enough to start it. It has two wires and no speed signal, so the board cannot read its speed.

Why Buy from NZN

Useful parts, fair prices and someone local to help.

I'm Lukas, an engineering student and maker based in Te Awamutu. NZN grew out of a CNC build that dragged on for months because every missing cable, bolt or electronic part meant another overseas order. I started the shop so Kiwi makers can spend more time building and less time waiting for the next parcel.
