120mm AIOs vs Air Coolers: What’s The Difference?

There are two main types of CPU coolers: liquid and air. Both types have their advantages and disadvantages, and the one that’s right for you will depend on your specific needs and preferences. Here is a detailed comparison of liquid and air CPU coolers:


In general, liquid CPU coolers tend to be more effective at cooling than air coolers. This is because the liquid has a higher thermal conductivity than air, allowing it to transfer heat more efficiently. As a result, liquid CPU coolers are often more effective than air coolers at keeping CPUs cool, especially under heavy workloads.

However, this doesn’t mean that air coolers are always inferior – some high-end air coolers can perform just as well as liquid coolers, and they may be a good choice if you don’t need the extra cooling power.


Air coolers are generally quieter than liquid coolers. This is since the only moving part in an air cooler is the fan, whereas a liquid cooler has a pump in addition to the fan. The pump can generate noise, especially when it’s working hard to cool the CPU. However, there are some quiet liquid coolers on the market, so noise levels will vary depending on the model.


Air coolers are generally easier to install than liquid coolers. They simply require you to mount the cooler to the CPU and attach the fan, which is usually accomplished with a few screws. On the other hand, liquid coolers require you to install a radiator and attach it to the CPU with hoses. This process can be more time-consuming and may require you to remove other components from your computer, such as the motherboard, to access the CPU.


Air coolers are typically less expensive than liquid coolers. This is because they have fewer parts and are easier to manufacture. This results in air coolers having less cost to manufacture and making them more affordable. However, some high-end air coolers can be just as expensive as liquid coolers. 

Overall, liquid CPU coolers tend to offer better performance than air coolers, but they can be louder and more difficult to install. On the other hand, air coolers are quieter and easier to install, but they may be less effective at cooling.

Ultimately, choosing between a liquid and air cooler will depend on your specific needs and preferences. If you want the best cooling performance and don’t mind a little extra noise, a liquid cooler may be the right choice for you. If you want a quieter, more affordable cooler that’s easy to install, an air cooler may be the better option

Best 120mm AIOs – Is A 120mm Radiator Enough For CPU?

A 120mm radiator can be sufficient for cooling a CPU, but it depends on the specific heat output of the CPU, the ambient temperature of the environment, and the cooling capacity of the rest of the system.

We recommended using a radiator that is at least as large as the size of the fan you are using, as this will allow for sufficient airflow and heat dissipation. For example, if you are using a 120mm fan, a 120mm radiator would be a good choice.

In addition to the size of the radiator, the efficiency of the radiator and the overall design of the cooling system will also play a role in its effectiveness. If you are building a new system and want to ensure that your CPU is adequately cooled, it’s a good idea to research the cooling requirements of your specific CPU and choose a radiator and fan combination that will be sufficient.

Buyer’s Guide – 120mm AIO Coolers

An all-in-one (AIO) water cooling system is a popular choice for CPU cooling because it is easy to install and requires minimal maintenance. A 120mm AIO is a good size for cooling a CPU, but there are a few key factors to consider when shopping for one.


It is essential to make sure that the AIO is compatible with your specific CPU socket and motherboard. Most AIOs will specify which sockets they are compatible with, but it is still a good idea to double-check. Some AIOs may also come with mounting hardware for multiple socket types, while others may be limited to a single socket. In addition to the socket compatibility, check that the AIO will fit properly in your system. Make sure there is sufficient clearance around the CPU and that the radiator will fit in your case.

Cooling performance

The primary purpose of an AIO is to cool your CPU, so it is essential to consider its cooling performance. Look for an AIO with a high TDP (thermal design power) rating, which is a measure of the maximum amount of heat that the best 120mm AIOs can dissipate. 

A higher TDP rating means that the AIO is capable of cooling more powerful CPUs. In addition to the TDP rating, you should also look for reviews or testing data that demonstrate the AIO’s cooling performance.

Fan speed and noise

The fan on an AIO plays a significant role in its cooling performance and overall noise level. Pay attention to the fan speed and noise level, as well as the overall design of the fan and radiator. Some AIOs use high-quality fans that are designed to be efficient and quiet, while others may be louder and less efficient. In addition to the fan itself, consider the fan mounting system and whether it is designed to reduce vibrations and noise.

Ease of installation

AIOs should be relatively easy to install, but some may be more straightforward than others. Look for an AIO with a well-designed mounting system to make the installation process as smooth as possible. Consider whether the AIO comes with all the necessary mounting hardware. You also want to look for any features that make it easier to install. A self-contained mounting system or pre-applied thermal paste are good examples.


AIOs can vary significantly in price, depending on their features and performance. Determine your budget and look for an AIO that offers good value for the price. Keep in mind that a more expensive AIO is not always better, and it is essential to consider the overall performance and features of the AIO rather than just the price.

Brand and warranty

Consider the reputation of the manufacturer and the warranty they offer. A good warranty can provide peace of mind and protect your investment in case of any issues. So, when on the hunt for the best 120mm AIO CPU coolers, look out for something from a reputable brand.
