The 5 Best 120mm AIO CPU Coolers 2023 – Buyers Guide

Best 120mm AIO CPU Coolers

Modern PCs can get very hot, especially if you are rendering or gaming for a long time. The stock cooling that comes with processors is more than enough for most cases, but the real problem shows in the long-term. Electronics and heat are part of the parcel. Take any electronics, and you will see it generates some heat as it uses electricity to power the device.

The same is the case for processors. To solve it, you can get a third-party CPU air cooler or step up the cooling using 120 mm AIO (All In One). An AIO CPU cooler is a liquid cooler that combines the radiators, water block, pump, fittings, fans, and tubes and offers a complete package to the user. That’s why it is known as AIO.

The catch is that they are expensive and can pose some risk to your PC due to liquid usage. But, in most cases, you are safe. Most of the AIO cooler manufacturer takes risks in consideration before releasing their product and in most cases. However, if something goes wrong, i.e., liquid spills, then most manufacturers cover that type of warranty where you are paid for the damaged goods. However, the path to get back the damages can be a long and not so pleasant one.

Anyway, in this guide, we will be listing the seven best 120mm AIO coolers that you can buy with your hard-earned money!

AIO cooler can be used as a standalone cooler for your entire PC, or you can also use it if you want your PC cooler water setup. In any case, 120mm AIO cooling for CPU provides the cooling performance. As we already know, the liquid is a good conductor of heat, and that’s why AIO liquid can be a good bet for good cooling performance.

But, before we list the best 120mm AIO cooler, we will go through the list of things that you should know before getting the AIO cooler for your PC.

120mm AIO Cooler: Things to look for best cooling

Check Clearance and Mounting

Great! You decided to get a 120mm AIO cooler. Before you get one, you need to make a check if you have the right clearance for it. You also need to know if the 120mm AIO supports the vertical or horizontal installation. This is important as it let you configure your airflow accordingly. If the 120mm AIO supports vertical mounting, then the air intake needs to be from the front. In horizontal mounting, the airflow can be either intake or outtake, based on your PC case.

Compatibility and Budget

You also need to make sure that your PC case and the processor on which you are using is compatible with the AIO you are going to buy.

RGB on Cooler

The RGB craze has been sweeping the industry for the past few years. You can find RGB on almost every type of hardware. The AIO is no different. It is nice to have RGB, but it is also nicer to have the option to turn it off. As a consumer, our taste changes over time, and one day you may not want to turn on the bling. In that case, having the option is helpful. Generally, a good 120 mm AIOs have the opportunity to turn them off.

Also, if you are an RGB fan, then you need to check how well it is implemented and if there is any form of the sync support for the RGB systems.

Is AIO cooler for you?

I know if you are reading this, you probably need one. However, AIO cooler comes with their risks like liquid spillage. The risks might not be worth it if you use a basic system with no such requirement for liquid cooling. What I meant to say is that a decent air cooler can also provide you the same value, and you do not have to worry about any liquid spillage to your system and potentially to damage it. However, the chance of it happening is almost nil, so there is not that much of a risk. In short, you should be wary of the risk before jumping on an AIO cooler, rather than regretting it later.

The longevity of the Cooler

We have liquid in the cooler, and is it allowing your CPU to be cooled passively. Also, it has a pump that is continuously working to pump liquid in and out. So, realistically speaking, a cooler can last anywhere between five to seven years. That’s not bad considering that it can last two of your builds providing value for an extended period. Most manufacturers rate their AIO cooler for 70000 hours, which means running the AIO cooler for eight years!
