Choosing the Right Components

▶ CPU and GPU Selection

Select a CPU and GPU that have compatible water blocks available, and ensure that the water blocks provide adequate coverage for the surface area of the components. This will ensure that heat is efficiently transferred from the components to the liquid cooling system.

▶ Radiator and Fan Selection

Choose a radiator that fits your case and has enough surface area to dissipate the heat generated by your components. The size and thickness of the radiator will affect cooling performance. Make sure to choose fans that are compatible with the radiator and have sufficient airflow and static pressure to efficiently move air through the radiator.

▶ Pump and Reservoir Selection

Select a pump with sufficient flow rate and head pressure to move liquid through the system and ensure adequate cooling. A reservoir is not strictly necessary, but it can help with filling and bleeding the system and can provide additional coolant capacity.

▶ Tubing and Fitting Selection

Choose tubing with a suitable diameter and material for your system, and fittings that are compatible with your components and tubing. Compression fittings are popular for their ease of use and reliability.

▶ Coolant Selection

Select a coolant that is compatible with your system components and tubing, and that provides sufficient heat transfer and corrosion resistance. Consider the color and appearance of the coolant, as it can contribute to the aesthetics of the system.

By carefully selecting each component, you can ensure that your liquid cooling system is compatible, efficient, and effective in cooling your components.

Building the Liquid Cooling System

▶ Preparation and Planning

Before you begin the installation process, it’s important to prepare and plan. This involves selecting the right components, measuring the dimensions of your case and components, and ensuring that you have all the necessary tools and equipment.

▶ Installation of CPU and GPU Water Blocks

The first step in building a liquid cooling PC is to install the water blocks onto the CPU and GPU. This involves carefully removing the existing heatsinks, cleaning the surfaces, and applying thermal paste before installing the water blocks.

▶ Installation of Radiators, Fans, and Pump/Reservoir Combo

Next, install the radiators and fans in your case, ensuring that they are compatible with each other and with your case. The pump and reservoir combo should also be installed at this stage, usually in the front or back of the case.

▶ Tubing and Fitting Installation

Once the water blocks, radiators, fans, and pump/reservoir combo are installed, it’s time to connect them with tubing and fittings. Cut the tubing to the appropriate length and connect it to the water blocks and pump/reservoir combo using fittings. Make sure that all connections are secure and leak-proof.

▶ Coolant Filling and Leak Testing

Finally, fill the system with coolant and test for leaks. Start the pump and run the system for a few minutes, checking for any leaks or other issues. Once you’re confident that the system is leak-free, you can start using your new liquid-cooling PC.

Remember to take your time and be careful throughout the installation process. Building a liquid cooling PC can be time-consuming and challenging, but the end result is a high-performance system that looks and performs great.
