Well, I think some have already guessed what a water cooling system is - it’s a water cooling system. What's happened water pump ? - This is a pump that forces coolant to circulate through the system. In this article I will tell you one example of a homemade pump.
The engine of our homemade pump is a cooler. I took the standard 60 mm. and for a current of 300 mA I advise you to take a 120mm cooler with a maximum current for normal results!
Let's start. First, let's break off its outer casing and wings. See the picture. Then we’ll cut it into 6 parts so that we can glue our own impeller.

We will coat with sealant or epoxy everything where water or coolant can get in, because our cooler will be completely immersed in liquid.

I cut an impeller from a blue pen cap. And glued it.

Next, you need to take a vessel the diameter of our engine and attach it there with glue. See photo.

Coat the outlet of the wires with sealant. We do everything without cracks.

We glue a transparent lid with a hole in the center on top - this will be the water inlet. The tube on the side is the exit.
