How to make a mini cooling system

Every computer needs a cooling system because when it heats up it needs to be brought back down to a normal temperature so that there are no risks. But computer cooling systems are usually very large, bulky, and expensive. However, we have a solution for his problem. Today we will show you how to make a mini cooling system that is very easy to make. Read more to find out how it is made.


Products needed for this DIY project:

1.      80 mm radiator

2.      Mini computer fan

3.      Small water pipes

4.      Water pump

5.      Cooling liquid

6.      Step down converter

7.      Cooling block

8.      Glue


Let’s get started with this DIY project!


Step 1:

First, let’s work on the fan of this mini cooling system. Screw the small computer fan on the 80 mm radiator with the help of four screws and a drill. You could even use a normal screwdriver if you don’t have a drill, just make sure that the screws aren’t loose.

Step 2:

Take a perfume bottle cap and drill a large hole in the center of the cap on the top. Use some sanding paper to smooth out the surface so that we have an even layer. Stick this cut-out perfume bottle cap to an ordinary water pump with the help of some glue. Apply a generous amount of glue on both surfaces so that it’s properly stuck in place.

Step 3:

While this cooling pump is drying, using a 3D printer, print out a lid for this cooling system. Put a rubber ring around the lid for friction and put it on top of the cooling pump that you made in the previous step to see if it fits.

Step 4:

Now it’s time to attach all these parts on a solid base. Take a block of PVC and put all the parts together like how it’s given in the picture attached below.

Step 5:

Let’s work on the electronics now. Since both the attachments work at a different voltage: the fan works at 12 volts and the cooler works at six volts, we need a step-down converter. Solder the wires of both these devices on the step-down converter using a soldering iron. Make sure to do this in a well-ventilated area since the fumes of the soldering iron can be dangerous if inhaled for long periods of time. Once the wires have been connected, attach this converter to the same PVC board carefully.

Step 6:

Use a small pipe to connect the top-hole cooling pump to the radiator and fan contraption. Take another small pipe and insert it into the back of the cooling pump and take a third small pipe and insert it into the other hole of the radiator. Connect the other ends of these two small pipes to a cooling block.

Step 7:

Your mini cooling system is almost ready. The last step is to put the cooling liquid into the device. Power up the device first and then put the cooling liquid into the water pump and watch the magic happen as your device circulates the coolant throughout the whole mini cooling system.

Your mini cooling system is now complete! This mini cooling system is portable, easy to make, and cost-effective unlike the expensive and bulky cooling systems available in the market. You could use this for a number of different purposes. Enjoy your latest creation!
