We have compiled a list of the top-performing AIO coolers after conducting extensive tests on their cooling efficiency and noise levels. Below are the models that stood out among the rest.
When selecting the optimal AIO cooler for your new PC or CPU upgrade, it is crucial to take into account key factors if you desire the highest sustained clock speeds for your Core i9-14900K or Ryzen 7 7800X3D, or if you simply wish for your system to operate quietly under heavy loads.
AIO coolers offer greater convenience and affordability compared to custom liquid cooling loops. Historically, they have consistently provided lower CPU temperatures and reduced fan noise compared to air coolers. However, it is worth noting that air coolers have made significant advancements and, in certain instances, have become more efficient and larger in size.
Ensure that there is adequate space available in your PC case to accommodate an AIO cooler, ideally positioned at the top or rear to expel the heat generated by your CPU out of the chassis. AIO coolers are commonly available in three different sizes, which are determined by the dimensions of the radiator and the number of fans the radiator can accommodate: 120mm (one fan), 240mm (two fans), or 360mm (three fans).
1. There are also 140mm, 280mm, and 420mm AIO coolers available, although they are not as widely used. Typically, the larger the radiator, the better the cooling capacity. However, factors such as radiator thickness, materials used, and the performance of fans and pumps also play a role in determining cooling efficiency and noise levels.
If your CPU doesn’t have a high number of cores or fast speeds of 5-6 GHz, and you don’t plan on overclocking, a 120mm AIO cooler should be sufficient. This type of cooler can typically be installed in the rear exhaust fan area of your PC case. However, it’s worth noting that Intel’s 12th and 13th Gen CPUs tend to require more demanding coolers. Similarly, AMD’s Ryzen 7000 lineup, although less thermally demanding than Intel’s chips, still requires effective cooling. If you prioritize lower temperatures and quieter fans, a 240mm AIO cooler would be a better option. Keep in mind that it may not fit in as many cases though.
If you are not worried about the cost and prioritize silent operation and low temperatures, you might want to think about opting for a custom cooling loop. To get a better understanding of their performance and aesthetics, take a look at our Blue Shift build feature. However, it is important to note that custom loops are significantly more expensive than other conventional cooling options, require a much more complex assembly and installation process, and can complicate future upgrades, particularly if you include your GPU in the cooling loop.
When searching for the top AIO cooler, it is essential to take into account thermal paste or another thermal interface material (TIM) to pair with your AIO cooler. While many coolers include some form of paste, either in a small syringe or already applied to the metal cold plate, it is crucial to ensure optimal thermal transfer between your CPU and cooler plate. Explore the variety of products we extensively evaluated to discover the most effective thermal paste for your CPU.
When looking for the best AIO cooler, it is important to consider thermal paste or another thermal interface material (TIM) to use with your AIO cooler. While most coolers these days will include some type of paste, either in a small syringe or pre-applied to the metal cold plate, it is essential to guarantee the most efficient thermal transfer between your CPU and cooler plate. Take a look at the numerous products we have thoroughly tested to identify the best thermal paste for your CPU.
