motor Idea # 1 - Using the
cooler In order to assemble the USB fan from the cooler, it usually takes no more than 15 minutes. First you need to prepare a cooler. From the device there are two wires - black and red. Strip the insulation by 10 mm and lay the prepared element aside.
Next, you need to prepare your wire. Cut one half of it and peel off the insulation in the place of the cut. Below it you will see four contacts, of which two are necessary: red and black. They, too, are cleaned, while the other two( usually green and white) are better cut off so as not to get in the way.
Now, as you understand, it is necessary to pair prepared contacts according to the color coding of the wires: red with red, black with black. After this, you must carefully insulate the connection points of the cable and make a stand. As for the stand, there is already a matter of your imagination. Some successfully use wire, some very interestingly cut out the landing nest in a cardboard box.
After all, a homemade mini fan connects to a computer and you can enjoy the work of your own electrical appliance.
Idea # 2 - Use the motor
In order to make a USB fan from the motor and CD, it takes a little longer, but in an hour you can easily make such an appliance yourself.
First, prepare all the elements of the device. In this case, you will need the impeller( blades) too.
To make an impeller we recommend using an ordinary CD-ROM.Straighten it into 8 equal parts and carefully cut to the center. Next, warm up the disc( you can use a lighter), and when the plastic becomes more elastic, bend the blades( as shown in the photo).
If the impeller does not bend, the air flow will not be created during the rotation of the disc. Here you need to feel the measure, so as not to overdo it too.
When the blades are ready, go to the creation of the main mechanism. Inside the disc, we recommend inserting a plastic stopper in which it is necessary to make a hole under the motor shaft. Carefully fix the core and proceed to create a USB fan support for the laptop.
Here, as in the previous version, it all depends on your imagination. Of all the improvised means, the variant with the wire is the most suitable. When the homemade USB fan is ready, we connect the wires of the motor to the wires of the cord, carefully isolate the twist and proceed to the test works.

As you can see, in order to make a fan from a cooler or motor from a machine, it takes less time and skills to work with electrical appliances. Even a beginner can cope with such a task!
