What is a Liquid CPU Cooler?

Liquid coolers are radiators that are designed for the cooling of the processor embedded in your computer. This radiator has a system where the heat sink is used to pass through liquid and cool off the processor. The liquid is used to absorb all the hot air from the processor, and then it moves outside the case, transferring the heat outside. The cooler liquid then moves back into the system to repeat the process again. It is a more efficient way of keeping your systems cool and ensuring the computer’s longevity and performance as the processor operates on higher speeds. 

How Does a Liquid CPU Cooler Work?

The liquid that is used inside these radiators is usually made of water and ethanol glycol. The reason why this solution is used instead of pure water is to prevent the liquid from freezing, inhibit any bacterial growth, and also prevent galvanic corrosion inside the tubes. There should be no debris inside; otherwise, the tubes get clogged. 

The ‘cold plate’ is a solid piece of copper that is attached to the CPU from one side, and several micro-fins from the other, for the liquid to flow through. A gasket holds this plate in place, and underneath that is another cover for the pump unit. Below these two are the Channel and Peller, which allows the flow of liquid from one tube rusted by the impeller through the copper micro-fins and outside the other tube. The compeller has a magnetic ring around it and is held in place by a plastic rod that allows it to spin freely when the motor is powered. 

How to Choose a Liquid CPU Cooler

Now that you have a detailed overview of how a liquid CPU cooler works, let’s dive into the features that should be examined before choosing a new liquid CPU cooler. 


If you are looking for a cooler that performs quietly and lowers the CPU’s temperatures without making any noise, you should go for a high-end AIO 280mm or 360mm radiator. This can instantly cool up your CPU and performs better than any of the air-coolers in the market. 

Computer Specs

The cooler’s radiator size is the biggest factor that needs to be considered. Since AIO coolers come in a lot of different sizes, you need to find the one that suits your CPU, and that can accommodate the radiator well inside the CPU. 


Some of the users want a sleek and minimal design of the cooler, one that doesn’t look or seem too bulky. Others prefer the high-end bulkiness of the cooler. It usually depends on the preference, but this is also one of the factors that should be considered before getting a liquid cooler. However, bulky ones can have issues with clearance, so it’s important that you check to see if the cooler is meddling with the hardware of your CPU or not.

Aspects to Consider Before Buying

There are several aspects that you need to keep in mind before purchasing a liquid cooler. Here are a few of the important ones that you should consider:


The quality and construction of the liquid cooler are really important as they determine the performance and the durability of the cooler. If you buy a cooler that is constructed with cheap materials, it will not be able to withstand the heavy load of the CPU.


You have to make sure that your table has enough space to install a liquid cooler. If you get a bulky cooler and do not have adequate space for it, it can get damaged easily, and will not work as efficiently as it would on the desktop. Radiators need open fan slots, and the reservoirs also require space in the case too. 


If you’re a hardcore gamer who wants the best use out of your CPU’s graphics card, you need the best cooling system, which means that a DIY cooling system would be better for you. If you want to keep your overclocking processor cold and benefit from minimized noise, then get a sealed liquid cooler to overcome these flaws. 

How to Install a Liquid CPU Cooler

Now that you’ve learned almost everything that you need to know about a liquid CPU cooler, let’s go over the instructions on how to actually install one at home. You can also watch the link of the video for a visual manual:

1. You will need to ensure that you have the radiator, the thumbscrews, fan screws, radiator screws, and the support screws before you start. You will also need the backplate and a screwdriver.

2. Remove the front and the back panels of the case of your CPU. Then, grab the radiator and fan and the set of long extended screws. The push method will be utilized here.

3. Secure the fan in place with the included four screws, and make sure it’s adjusted in a way that the lead wires shouldn’t be in an odd position

4. Take the fastener corresponding to the socket type. It is a squared red pattern for Intel, and rectangle for AMD. Latch it to the base of the water cooler. It should lock after some rotation. 

5. Take the corresponding backplate and secure it from behind your motherboard. 

6. Grab the support screws with equal lengths and secure in the forepins. 

7. Apply the thermal paste on the base of the water block.

8. Mount the radiator and secure it to the PC’s chassis, preferably at the front or the back. 

9. Once the radiator and the fan are secured, grab the opposite end of the AIO cooler, the water block, and align the fastener with the support screws. 

10. Slide the block on top of the CPU through the supports, and while holding the block in place, use the larger thumb screws to sandwich the entire assembly together. Do this in a cross pattern without using a screwdriver. 

11. Double-check that your pipes are routed appropriately and ensure that no cable leads are wrapped up in circuit components or fans. 

12. Grab the shortest cable lead and plug it into the CPU fan header on the motherboard. The longer cable is for USB support. 


Hopefully, this article was able to help you decide which liquid CPU cooler is best for you and suits your needs. These kinds of devices need a lot of research and thorough checking, which is why this article was designed to eliminate some of the doubts and give you some clarity. So, good luck shopping!

People Also Ask

If you still have a few ambiguities in mind that need to be cleared out, you can read this portion and get answers on the doubts that you have. Just go over these frequently asked questions to gain some insight on the functionality of the liquid coolers for your CPU:

Can Liquid Cooling Leak?

You can encounter pump failure when you purchase a liquid cooler for your CPU, which can lead to some level of leakage. If you are overclocking heavily, then liquid cooling is the best option for your motherboard; otherwise, regular air coolers are fine. Hence, yes, liquid cooling can leak. 

Do Liquid Cooling Systems Require Maintenance?

Yes, liquid cooling systems do require maintenance. It usually depends on the quality of the cooler you purchase; however, you have to go through the hassle of replacing the card and periodically top-off fluid levels. You also need to check pipes for any debris so that it doesn’t get clogged. 

How Often Should You Change Liquid Cooling PC?

This depends largely on the type of tubing the cooler has. However, with the modern coolants with innovative technologies, the fluid should remain active in the pipes for about a year. This largely depends on the material; otherwise, you should get it checked regularly for any debris or clogs.
