The Best AIO Coolers for Gaming PC 2023

The Best AIO Coolers for Gaming PC

When it comes to PC building, most gamers rave about processors and graphics cards. However, there are other important computer components that not only ensure excellent gaming performance but also improve the aesthetics of your PC. One of these components is the cooling system.

Responsible for keeping your computer’s temperature low, these systems can take the form of either an air or liquid cooler. While air coolers are the more popular variant and are ideal for the majority of computer users, an all-in-one (AIO) or liquid cooler is another solution for casual and hardcore gamers. Read on to learn more about liquid cooling and the best AIO coolers for a gaming PC in 2023.

What is Liquid Cooling in PCs?

If you haven't built a PC yet or only used air coolers in all your builds, you might have concerns about liquid cooling and what it even means. A liquid or water cooling system works like a car’s radiator. However, instead of cooling the car’s engine, it keeps your computer’s thermal performance stable. 

It does this by circulating liquid coolant through the heat sink attached to your CPU. As the coolant runs through the heat sink, the heat generated is transferred from your processor to the liquid. Tubes then move the hot liquid to a radiator at the back of your case. The heat is dissipated to the ambient air, and the now cool liquid flows back to the heat sink to repeat the cooling loop.

While having a liquid substance in close proximity to sensitive electronic components might be alarming, liquid cooling systems are safe. However, they should be properly installed, and the cooling system you pick must be high-quality.

Is an AIO CPU Cooler Worth It?

Whether or not an AIO CPU cooler is worth it depends on what kind of PC user you are. If you’re just a general user who only makes documents, browses the internet, and uses non-demanding software, then an air cooler should be enough for you. However, for power users and gamers, a water cooling system is worth it for the many benefits it offers.

Better Heat Dissipation

Liquid can dissipate heat faster than air. Thus, AIO coolers offer a superior cooling capability. While light programs like MS Word won’t cause too much heat buildup, demanding programs like modern AAA titles can cause CPU heat to ramp up fairly quickly. To avoid thermal throttling and reduced game performance, you need high-performance CPU cooling that only AIO coolers can deliver. 

Less Maintenance

An AIO cooler is easier to maintain than alternatives like a custom water cooling loop. To clean the fans, all you need is some compressed air and a small brush. There’s no need to do any complex and risky disassembly. Premium water cooling systems are also quite robust, with some units lasting for over ten years.

Lower Noise Level

A CPU cooler’s fans can get noisy, which can distract gamers and ruin immersion. Fortunately, most AIO coolers have an efficient radiator that can keep PC temperatures stable even when the fan speed is set to low. Hence, if you’re a gamer who doesn’t want to constantly use headphones, an AIO cooler can offer you a quiet gaming experience.

What Liquid Is Used in AIO?

AIO coolers use a liquid coolant solution to dissipate heat from your CPU. Here are the most common liquids and additives used on AIO cooling systems.

Distilled Water

Distilled water is a popular and inexpensive non-conductive coolant. It’s essentially vaporized water that has been turned back to liquid. Despite being initially non-conductive, distilled water eventually regains conductivity as it passes through the cooling loop and collects ions from the radiator and other AIO components. Hence, you should ensure that your cooling system is properly installed and conduct regular inspections to avoid damage from leakage.

Deionized Water

Deionized water is a more expensive coolant that has undergone a complex chemical process. This process removes most of the ions and dissolved minerals in the liquid, making deionized water the better coolant option in terms of conductivity. 

Coolant Additives

Essential coolant additives are likewise mixed with distilled or deionized water. One of these additives is ethylene glycol. This compound prevents bacterial growth and corrosion. Moreover, dyes and colors are sometimes used to make the system pop even further. However, the solution is often kept clear to avoid slime buildup and avoid pH imbalances.

Do You Need To Refill AIO Coolers?

AIO coolers do not need to be refilled and are almost maintenance-free. These CPU coolers have a closed-loop system. The pump, radiator, and tubing are all built-in, making the liquid coolant inside well-secured and less prone to contamination. Since the coolant is unlikely to get compromised, there’s no need to refill or replace it.

This is in contrast to open-loop liquid cooling systems, whose pumps, reservoirs, and radiators are divided into different segments. Because of their complex and less compact design, open-loop systems need to be inspected, drained, and cleaned every year or two. The liquid coolant within likewise needs regular refilling and replacement.

How Long Do AIO Pumps Usually Last?

The lifespan of AIO pumps will depend on the overall quality of the cooling system. For example, an AIO pump from a subpar manufacturer can fail in just a couple of months. Meanwhile, a water cooling pump from reputable brands like Cooler Master, Corsair, and MSI can last anywhere between seven to ten years, sometimes even longer.

To put things into perspective, modern motherboards have the same average lifespan. Hence, the longevity of AIO coolers is within industry standards.

Moreover, there are several factors that impact the lifespan of AIO pumps and coolers in general. Installation issues, such as incorrect tubing placement, can cause bubble buildup and hamper liquid movement. These can damage the pump. Corrosion due to poor coolant mixture, substandard welding, or leakage can also cause premature pump failure.

Thus, to lengthen the life of your AIO cooler, you should properly install the cooling system and regularly monitor its performance.

Which Is Better? Liquid Cooler or Air Cooler?

If you’re a gamer or someone who uses demanding computer applications, a liquid cooler is generally the better choice. However, some arguments in favor of air coolers can be made. Here are the factors you should consider to determine the right PC cooling solution for you. 


In terms of temperature regulation and noise levels, liquid coolers have a clear advantage over air coolers. An air cooler dissipates heat using a heatsink and a fan. The fan sits at either the top or side of the heatsink and blows air away from the CPU. This cools the processor down. While air coolers can keep CPU temperatures low, a liquid cooler can keep your system cooler more efficiently and quickly. Moreover, liquid coolers produce less noise compared to even the most silent air cooler. 


Generally, air coolers are more affordable than AIO coolers. This is expected since AIO coolers have a more complex cooling mechanism and provide better performance. For power users, the difference in price is justified. However, there are gamers who only use a budget gaming PC and don’t need the performance boost of a liquid cooling system. Moreover, some PC builders prefer allocating more funds to other components like the CPU, GPU, RAM, and storage. For these people, an air cooler would be a better option.


Air and liquid coolers have completely different architectures. Most air coolers have a huge heatsink, although the rest of their components tend to be compact. In contrast, liquid coolers don’t have any bulky parts, but they need enough space for the radiator, CPU block, and coolant tubes. Hence, when it comes to space accommodation, the type of CPU cooler that’s best for you will depend on the size and type of your PC case. 


Since air coolers only consist of two main parts, they’re easier to install. Meanwhile, installing a liquid cooler requires more skill, especially since you have to find a proper place for its individual components. Moreover, you have to be more cautious when installing an AIO cooler to avoid leaks. If you’re a veteran PC builder, then either of these CPU coolers would be a breeze to install. However, if it’s your first time building a gaming PC, it’s advisable that you get an air cooler.


Liquid coolers are great CPU coolers if you’re after superior cooling and noise reduction. From the Lian Li Galahad to the MSI MEG CoreLiquid S360, there are several excellent AIO coolers available in the market. Just make sure to consider all factors, like case size and your PC-building experience, before you select a water cooling system.
