Recent high-end processors fromthe Raptor Lake RefreshandRyzen 7000 serieshave made it extremely important to understand why users shouldn’t settle for just any CPU cooler.
Record-breaking performanceand increasingly high temperatures contribute to the need for an efficient CPU cooler. This is especially true in contrast to processors from previous generations. CPU chips are now more power-hungry than ever. Likewise, they run at much higher temps due to their die design. This particularly applies well to the Ryzen 3D processors, which have unusual stacking that creates thermal issues. However, with a powerful cooling solution, thermals can be controlled to achieve higher clock speeds and maintain them throughout the operation.

Corsair iCUE H170i Elite CAPELLIX XT
ASUS ROG Ryujin III 360 ARGB AIO Liquid Cooler
Although there is a wide array of high-end CPU coolers available, the best-performing are easily AIO coolers. This is because of their water cooled design, utilizing the efficiency and lower temperatures associated with liquid cooled PC loops, and implementing this cooling power through a convenient, all-in-one (AIO) package.
Whether users are looking for an AIO cooler to maintain their CPU turbo speed or want to achieve higher clock speeds through overclocking, Game Rant has compiled a list of the best AIO coolers for every budget.

How to Choose an AIO CPU Cooler
Radiator size:AIO coolers are categorized based on their radiator sizes. These sizes tend to vary, but 120mm, 240mm, 280mm, 360mm, and 420mm radiators are the most popular ones on the market. While the smaller ones are ideal for power-efficient and budget gaming CPUs, bigger radiators are aimed toward fulfilling the cooling requirements of higher-end chips that tend to generate more heat. However, bigger coolers may have a compatibility problem depending on the PC case being used.
Fan and Pump speed:Each AIO cooler comes with a dedicated pump and cooling fans, which run at a particular range of speed measured in RPM. Higher speed means better heat dissipation but at the same time, more noise is generated. While the speed of the fans or pump can be controlled, it’s best to figure out how much performance users may want before the purchase.

Software compatibility:AIO coolers that come with dedicated software support are easier to customize or control through the software. Users can change the fan speed, customize the RGB LEDs, and make custom speed graphs. However, AIO coolers without software support can be controlled via BIOS, which can be a frustrating task.
Tubing:Smaller coolers like 120mm AIO ones have shorter tubing, making it difficult to install the radiator in the front panel. This might not sound like a big deal, but depending on the PC case, installation of the radiators can pose a problem. Similarly, well-sleeved tubing should be preferred for more durability.
