DIY mini water cooling system

To reduce the heat on your computer's CPU, you can switch from air to liquid cooling. Usually such an upgrade is accompanied by large costs. If you choose components wisely, then it is quite possible to assemble a budget mini system.
Such a small installation can cool not only the computer processor, but also, say, a power amplifier chip in order to improve heat dissipation.

Materials:

• liquid radiator 80 mm -
  
• fan -
  
• mini water pump -
  
• deodorant cap;
  
• plywood or plank;
  
• step down converter from 12V to 6V -
  
• hose -
  
• aluminum CPU water cooling block -

The manufacturing process of a liquid cooling system for PCs and more

A fan is screwed to the liquid radiator.

Next you need to modify the pump.

To do this, you will need to drill through the center of the deodorant cap.

Its outer side of the bottom is sanded to create a rough surface for gluing. Then it is glued to the pump using epoxy glue. The hole in it is aligned for the pump fluid intake.



While the glue dries, you need to make a plug with a fitting for the glued lid.It can be printed on a 3D printer, machined or selected. To make it fit tightly, grooves are made on it for sealing rubber bands.


A radiator with a fan and a pump are installed on a base made of any sheet material. Since the pump is 6V, a step-down converter will be required to power it from a 12V computer unit. It is soldered to the pump contacts.



After this, a hose is connected to the pump, the second end of which is connected to the radiator. Another tube is put on the fitting of a homemade cap. The free ends of the hoses are then pulled over the CPU water cooling unit.


To start the system, you need to open the cap on the running pump and pour coolant into it.


The pump will pump it around and start draining it back. You should draw the liquid level slightly below the edges to allow its thermal expansion, after which the lid is closed.
