120mm AIOs don’t provide significantly better cooling than high-end air CPU coolers. In other words, a 120mm AIO and a stock air cooler of a high-end CPU are mostly similar in their performance. But in most cases, AIOs are ahead of air coolers.
As water has a higher specific heat capacity and thermal conductivity than air, AIOs can keep your PC slightly cooler than air coolers. And in long-term use, AIOs can extend the health of your PC more than air coolers do.
Let’s discuss more details about 120mm AIO vs Air Cooler and identify which one is better between these coolers.

120mm AIO vs Air Cooler – Let’s See Which One Is Better?
A 120mm AIO may not give you extra performance, but it is quieter than the air cooler. AIO cools down your CPU by both air and water and that is why it makes less noise than an air cooler.
Liquid cooling works very much like a radiator in your car or home. This system cools off the CPU by taking the heat from the CPU by water and dissipating it by the fans. On the other hand, an air cooler uses a heat sink and air instead of water which is used in an AIO.

Pros & Cons of Air Coolers
Here are the pros & cons of Air Coolers –
Air Coolers | |
Pros | Cons |
The biggest pro of an air cooler is it is affordable. | An air cooler is louder than AIOs. |
An air cooler does not need maintenance as much as an AIO. | Most of the time, these are bulky and look less attractive. |
There is no chance of leaking so you do not need to worry about it. | Air cooling technologies take up more space inside of a PC case than AIOs |
The ratio of price to performance of an air cooler is impressive. | Sometimes it bumps against other components like RAM or PSU (Power Supply Unit). |
Its cooling rate is limited on an air cooler. |
Overclocking | AIO vs air cooler
As AIOs keep CPUs cooler than an air cooler does, AIOs play a better role if you want to overclock your CPU. Because an overclocked CPU heats up more and may get damaged if not properly handled.
Style | AIO vs Air Coolers
We really should talk about the style of the coolers. Nowadays, decorating the PC with RGB strips, RGB fans, and stylish coolers is a common trend. And coolers play the most vital role in decorating the PC. Between the water cooler and air cooler, the water cooler looks more stylish.

As you can see in the picture above, the 120mm AIO makes the internal space more usable and it looks cleaner than an air cooler. As it takes less space inside the case, the RGB lights of the fans and RAMs are more visible here.
Frequently Asked Questions
Are 120mm AIO Coolers Good?
120 mm AIO coolers are good almost every way – it is compatible with different cases, and can cool better than other coolers. However, the price of this cooler is little-bit higher than regular cooler and you may need more effort to install this cooler.
Should I Switch from Air Cooler to AIO?
AIO coolers are comparatively cheap, compact, good-looking, and provide more than enough cooling for entry-level to mid-range CPUs. So, switching from air cooler to AIO is always a good decision.
Is Air Cooler Better than Liquid?
No, air cooler isn’t better than liquid coolers. It is true that air coolers are quite good at relocating heat away from the CPU, but the heat is dispersed into the case after that. As a result, the temperature of your system may increase. Liquid coolers on the other hand relocate head off the CPU and through them outside of the system via the fans on the radiator. So, liquid coolers are actually do a better job than air coolers.
Should I Get an Air Cooler in Humid Conditions?
The effect of an air cooler is dramatically decreased when utilized in extremely humid situations. This is because coolers cool the air by adding humidity to it, and once the air is saturated, it can no longer absorb any more moisture, rendering the device less effective.
Conclusion
Air coolers are quite good at relocating heat from CPUs. But the heat is then dispersed into the case, so the other components might get hotter. You can open a side of the case permanently but then you have to sacrifice the aesthetics of the PC. AIOs handle the situation best, as they take the heat outside of the case.
