How to Build a Liquid Cooled Gaming PC

Are you tired of your gaming PC overheating and causing your games to lag? Are you looking for a way to keep your PC running cool even during intense gaming sessions? If so, then it’s time to consider building a liquid-cooled gaming PC. In this article, we will show you how to build a liquid-cooled gaming PC step by step, from selecting the right components to assembling the PC.

Selecting the Right Components

Selecting the Right Components

The first step in building a liquid-cooled gaming PC is to select the right components. Here are the components you will need:

1. CPU

The CPU is the brain of your PC and one of the most important components you’ll need to select. When it comes to gaming, you want a CPU that can handle the demands of your favorite games without slowing down. Some popular choices include the Intel Core i5 and i7 and the AMD Ryzen 5 and 7.

2. GPU

The GPU is the component that handles the graphics of your PC. For gaming, you want a powerful GPU that can handle the latest games at high settings. Popular choices include the Nvidia GeForce RTX 3060 Ti and the AMD Radeon RX 6700 XT.

3. Motherboard

The motherboard is the component that connects all the other components together. You want to select a motherboard that is compatible with your CPU and GPU and has the necessary features you need, such as Wi-Fi and Bluetooth.

4. RAM

RAM is the memory that your PC uses to run programs and games. For gaming, you want at least 16GB of RAM, but more is better.

5. Storage

You will need a storage device to install your operating system and store your games and files. You can choose between a traditional hard drive or a faster solid-state drive (SSD).

6. Power Supply

The power supply is the component that powers all the other components in your PC. You want to select a power supply that can handle the power demands of your CPU and GPU.

7. Liquid Cooling System

The liquid cooling system is what keeps your PC running cool during intense gaming sessions. You will need a liquid cooling system that is compatible with your CPU and GPU and has enough cooling capacity.

Assembling the PC

Assembling the PC

Now that you have selected the right components, it’s time to assemble your PC. Here are the steps to follow:

1. Install the CPU

The first step is to install the CPU into the motherboard. Follow the manufacturer’s instructions carefully to avoid damaging the CPU.

2. Install the RAM

Next, install the RAM into the motherboard. Make sure to install the RAM in the correct slots and apply equal pressure to both sides to ensure it is installed correctly.

3. Install the Motherboard

Install the motherboard into the case and secure it using the screws provided. Make sure the motherboard is level and that all the ports line up correctly with the openings in the case.

4. Install the GPU

Install the GPU into the PCIe slot on the motherboard. Make sure to secure it using the screws provided and connect the power cables to the GPU.

5. Install the Storage

Install the storage device into the case and connect the necessary cables. If you are using an SSD, make sure to install it in a location that allows it to dissipate heat properly.

6. Install the Power Supply

Install the power supply into the case and connect the necessary cables to the motherboard, GPU, and storage devices.

7. Install the Liquid Cooling System

To install the liquid cooling system, you will need to carefully follow the manufacturer’s instructions for your specific system. Generally, the installation process will involve mounting the water block onto the CPU, attaching the pump to the radiator, connecting the tubing, and filling the system with coolant.

First, mount the water block onto your CPU using the appropriate mounting hardware. Be sure to apply thermal paste to ensure proper heat transfer between the CPU and water block.

Next, mount the radiator in a suitable location in your PC case. The radiator should be mounted in a position where it can easily dissipate heat from the coolant. Many cases have specific areas for mounting radiators, so check your case’s manual for guidance.

Once the radiator is mounted, attach the pump to the radiator using the included hardware. The pump should be positioned so that it can circulate the coolant effectively through the system.

Next, attach the tubing to the water block and pump using the appropriate fittings. Make sure the tubing is routed cleanly and securely without any sharp bends or kinks that could restrict flow.

Finally, fill the system with coolant, following the manufacturer’s instructions for your specific system. It’s important to use the correct type of coolant and to fill the system to the recommended level to ensure proper cooling performance.

Once the system is filled, turn on the pump and check for any leaks or issues. Monitor the temperatures of your CPU and GPU to ensure they are running within safe ranges. If everything is working correctly, you’re ready to move on to the next step!

8. Connect the Cables

Connect all the necessary cables to the motherboard, GPU, storage devices, and liquid cooling system. Make sure to double-check that everything is connected correctly.

9. Power On the PC

Power on the PC and make sure everything is running correctly. Check the temperatures of your CPU and GPU using software such as MSI Afterburner to ensure they are running within safe ranges.

10. Install Operating System and Drivers

Install your operating system and all necessary drivers for your components. Make sure to download and install the latest drivers for your GPU to ensure optimal performance.

Maintenance and Upgrades

Maintenance and Upgrades

Congratulations, you have successfully built your liquid-cooled gaming PC! However, it’s important to keep your PC running smoothly by performing regular maintenance and upgrades. Here are some tips:

  • Clean your PC regularly to prevent dust buildup that can affect cooling performance.
  • Monitor your temperatures regularly and adjust fan speeds or overclocking settings if necessary.
  • Upgrade your components as needed to keep up with the latest games and technology.

By following these tips, you can keep your liquid-cooled gaming PC running smoothly for years to come.


Is liquid cooling better than air cooling for gaming PCs?

Liquid cooling is generally more efficient and effective than air cooling, especially for high-performance gaming PCs.

Do I need to use a liquid cooling system for my gaming PC?

No, you can use air cooling if you prefer. However, liquid cooling can provide better cooling performance and allow for higher overclocking.

How much does it cost to build a liquid-cooled gaming PC?

The cost will depend on the components you choose, but a high-performance liquid-cooled gaming PC can cost upwards of $2000.

Can I install a liquid cooling system myself?

Yes, but it’s important to follow the manufacturer’s instructions carefully to avoid damaging your components.

Do I need to refill the liquid cooling system?

It depends on the type of liquid cooling system you choose. Some systems are sealed and do not require refilling, while others may require periodic maintenance and refilling.


Building a liquid-cooled gaming PC can seem intimidating, but with the right components and careful assembly, it can be a rewarding and enjoyable experience. By following the steps outlined in this article, you can build a PC that can handle the demands of the latest games without overheating or slowing down.
