Best CPU Coolers for Ryzen 7 5800X

The new AMD Ryzen 5000 Series CPUs have been announced, and gaming enthusiasts now have a new CPU to look forward to. Maximizing the potential of the previous Zen 2-generation processors, these CPUs hold the crowns for the best gaming and best content creation CPUs, all in one. The CPU that is looking to become the best value of all Ryzen 5000 Series CPUs is the Ryzen 7 5800X – especially when it comes to gaming.

What differentiates these Zen 3 processors, from previous AMD CPUs, is that they have expanded CCXs (Core Complex) that are able to hold 8 cores and 32 MB of Level 3 cache – up from the 4 cores and 16 MBs of the Zen 2 CCX. This means that inter-core latency is drastically reduced, which is especially important for gaming and single-core performance. Due to the fact that gaming applications will not use more than eight cores and 16 threads – nor will they in the foreseeable future, as this is also the limitation of next-generation gaming consoles – means that having a multiple CCX Ryzen CPU (like the R9) will inevitably become redundant. This is also apparent in the fact that the gaming benchmarks shown for the Ryzen 9 5900X and Ryzen 9 5950X display an almost equal performance (with some games even favoring the R9 5900X) in comparison to the i9-10900K. This only goes to show that anything more than the necessary core and thread counts will provide little to any enhancement in FPS for gaming.

The Ryzen 7 5800X has one maximized CCX, which is really all that is needed for top-level performance for several years to come. Of course, it must be said, that AMD has increased the prices of their Ryzen CPUs, compared to the launch prices of Zen 2, and this time around they also will not include a stock cooler (the only exception being the Ryzen 5 5600X).

When purchasing a CPU cooler, it is wise to invest as much as possible, because the CPU cooler will not only allow you to maximize the power of your processor’s overclocking capabilities, but it will also last for several upgrades of the CPU. That is why we’ve compiled a list of the best CPU coolers to pair with the Ryzen 7 5800X based on both price and performance.

For under $50, the Scythe Mugen 5 Rev.B provides optimal cooling, with noise levels that rival some of the best CPU coolers the industry has to offer.

This CPU cooler makes use of a single 120 mm Scythe Kaze Flex fan that outputs an airflow of 51.17 CFM and static pressure of 1.05 mmH2O, utilizing fluid dynamic ball bearings that provide an incredibly low noise level of under 30 decibels –while maintaining a standard lifetime of 120,000 hours. When TweakTown put the Scythe Mugen 5 Rev.

B to the test, it surprisingly performed very close to CPU coolers that are upwards of twice their price. Additionally, it is the only cooler that was tested that did not exceed 30 decibels, even at overclocked loads (12V).

Not only will this cooler last, but it can also be upgraded by mounting a second 120 mm fan; so it is not just affordable, but it is also futureproofed. You can find the Scythe Mugen 5 Rev.B for only $48.99 – a no-brainer for those looking to chill the Ryzen 7 5800X without breaking the bank.

Buying Guide: Choosing the Right CPU Cooler for Your Needs

Compatibility with Ryzen 7 5800X

When selecting a CPU cooler for your Ryzen 7 5800X, ensure that the cooler is compatible with the AM4 socket, which is used by this processor. Most coolers come with mounting brackets that cater to different socket types. However, it is crucial to double-check the compatibility before making a purchase.

Cooler Size and Clearance

CPU coolers come in various sizes and designs, which can affect the overall compatibility with your system. Consider the dimensions of the cooler and the clearance required for your case, RAM, and other components. Low-profile coolers are ideal for small form factor (SFF) builds, while larger coolers can offer better performance in full-sized cases. Be sure to measure your case’s clearance and compare it with the cooler’s dimensions.

Noise Levels

Noise can be a significant concern for some users, especially if the computer is used in a shared or quiet environment. CPU coolers have varying noise levels, measured in decibels (dB). Typically, air coolers tend to be quieter, but some AIO coolers have advanced fan designs that minimize noise. Look for coolers with low noise levels or adjustable fan speeds to control the noise according to your preferences.

Cooling Performance and Efficiency

The primary purpose of a CPU cooler is to maintain optimal temperatures and prevent overheating. Consider the cooling performance of the cooler, measured by its ability to dissipate heat effectively. AIO coolers generally provide better cooling efficiency due to their liquid cooling systems, but high-quality air coolers can compete with them. Analyze the cooler’s thermal performance, taking into account its heat dissipation capacity, the number of heat pipes, and the cooling solution used.

Installation and Ease of Use

A straightforward installation process can save time and frustration. Look for coolers that come with clear instructions and mounting hardware that is easy to use. Some coolers may require the removal of the motherboard for installation, which can be a cumbersome process. Opt for a cooler with a user-friendly installation method to ensure a hassle-free experience.

Budget Considerations

When choosing a CPU cooler, consider your budget constraints. While some high-end coolers offer excellent performance, they might be overkill for your specific needs. Determine the ideal balance between price and performance, considering the other factors mentioned in this buying guide. There are affordable coolers available that offer great value for their price.

Aesthetics and Customization

For those who prioritize the appearance of their PC build, aesthetics, and customization options are essential factors. RGB lighting, customizable color schemes, and unique designs can enhance the overall look of your setup. Choose a cooler that complements your system’s design and allows for personalization, if that is important to you.


We have discussed four exceptional CPU coolers for the Ryzen 7 5800X, each excelling in different categories: the Scythe Mugen 5 Rev.B (budget), Noctua NH-L12S (low-profile), Corsair H115i Elite Capellix (AIO), and Noctua NH-D15 (air cooler).

Choosing the right CPU cooler for your Ryzen 7 5800X is crucial for optimal performance and longevity. Consider factors such as compatibility, size and clearance, noise levels, cooling efficiency, installation, budget, and aesthetics. By carefully weighing these aspects, you can make an informed decision and select a cooler that best meets your needs and preferences.
