CPUs are the ‘brain’ of the PC, processing instructions given to it via computer programs. All modern PC CPUs need to be cooled, the more powerful the CPU, the more powerful the cooling solution needed to keep it in check. This is especially true for the 5950X, as it’s an extremely powerful PC with a decently high default TDP of 105W. So we’re going to need a very effective cooling solution to keep it cool. So what is the best AMD Ryzen 9 5950X CPU cooler? 

In this article, we are going to outline the best CPU cooler for the Ryzen 9 5950X

How do CPU coolers work? 

CPU coolers are pretty complicated in terms of physics, but they aim to fulfill one single purpose and that’s to dump as much heat out of the CPU as possible. CPU coolers achieve this in a few ways. 

There are some basic physics to understand here if you want to know how CPU coolers work. Heat dissipation is performed via three main methods, conduction, convection, and radiation. Most CPU coolers use at least one of the three methods at some stage throughout the cooling cycle. 

Heat moves from the CPU to the cold plate, then through the heat pipe, the heat is transferred to the heatsink. This is where, with the aid of a fan, the heat is dissipated into the air around the heatsink. 

This is a very simple explanation of how CPU coolers work and we have one far more in-depth in our “Best CPU cooler for Ryzen 9 5900X” article. 


Things to consider 

There are a few things to consider when opting for a brand new CPU cooler such as air vs liquid, socket, TDP, and more. We will run through everything you need to know before picking the cooler that’s right for you and your 5950X. 

TDP 

TDP is the enemy and the very reason we’re installing a CPU cooler in the first place, TDP stands for thermal dynamic power and is the maximum amount of heat a component can output at its maximum load. 

A more powerful CPU may contain more cores or threads, clocked at a higher speed, for example, the addition of these features increases power consumption, creating more waste. 

When any electrical component operates, it wastes some of its energy as heat energy. This is a natural occurrence, all we can do is integrate IHS’ onto the CPU die to allow a more efficient transfer of heat between CPU and cooler. 

Make sure the TDP dissipation statistic on the CPU cooler you’re planning on getting exceeded the TDP of your CPU, especially if you plan on overclocking. 

AIR vs liquid cooling 

Both air and liquid cooling are viable options when it comes to PC cooling, but one is superior to another in terms of performance. 

Air cooling

Air cooling has been around since the dawn of computers, and even the most advanced forms of water cooling still use forms of air cooling to dissipate heat away from its radiators. 

There’s not a whole lot to say about air coolers, other than the fact they are some of the cheaper options on the market. Cheap doesn’t necessarily mean bad though, as you will see some air coolers can compete with lower-end liquid coolers on the market. 

Air coolers are easy to install and maintain, and their simplicity is one of their strengths. 

Liquid cooling

Liquid cooling comes in a couple of different forms, AIOs and custom loops. AIO coolers are all the goodness of custom loops rolled into one neat little package, whereas custom loops can be as complex or as simple as you want them to be. 

AIOs

AIOs consist of a water block, a built-in pump, transport tubes, a radiator, and a few fans. These components put together comprise a mid-level water cooling system. 

AIOs are closed, meaning you cant open them up to access the pump or any of the water block internals. Some, however, do include a fill port to allow you to top up your AIO cooler with a cooling solution. This enclosed design means that AIOs are less susceptible to dust build-up and damage around the pump area but still suffer the same dust build-up on radiators and fans – depending on your airflow configuration. 

AIOs are generally less expensive than custom loops, but they can be much more expensive than a good air cooler. There are a lot of AIO’s out there and they all come in different shapes and sizes, some even feature LCD screens mounted onto the water block. 

Despite the price increase, AIOs do generally perform significantly better than air coolers. 

Custom loops

Custom loops are the most expensive way to regulate temperatures in your PC, costing anywhere from $150 to around $1000 for a decent setup. 

The goal of custom loops is the same as AIO coolers, to use water to draw heat from the CPU to a radiator. The trick is that custom loops do it a lot more efficiently.  

Custom loops can use any size reservoir with a pump capable of moving large volumes of water rapidly. They can also incorporate whatever size radiator is required multiple times into the system. This combination of advantages means custom loops can cool a lot more efficiently than AIOs as they aren’t restricted to a specific size. 

Maintenance is a lot harder on a custom loop, however. Custom loop maintenance involves draining the entire system of all water and then attempting whatever repairs or cleaning is necessary. Not to mention the twice-yearly water replacement you should perform as standard.  

Besides the points we mentioned, a custom loop isn’t too much different than an AIO in an operational sense. 

Socket

When selecting any CPU cooler it’s important you make sure that the cooler fits the CPU socket on your motherboard. This isn’t usually a problem in this day and age as most coolers ship with native compatibility for most sockets. However, if you’re opting for an older cooler whilst owning a newer socket, it would be wise to check the compatibility sheet online. 

Spacial requirements 

Ensure your PC case supports the CPU cooler you’re planning on purchasing, this may be a height requirement for air coolers or radiator dimensions for liquid coolers. Having a CPU cooler that does not fit into your case is less than ideal, as improper mounting can significantly diminish the efficiency of the cooler.

Editor’s Rating

The ASUS ROG Ryujin II is one of the most visually pleasing AIO coolers on the market, mostly thanks to its huge pump and vivid, industrial-looking LCD screen.

This model is available in both 240 and 360mm variants, giving builders with different form factor cases some flexibility regarding the size. 

The main talking point of the Ryujin II is the addition of the LCD screen, which allows any image or GIF to be displayed. The LCD screen has full AIDA64 support, meaning you can display current system state information on the 3.5″ full-color screen if you so wish, but if you want to display your favorite cat gif, that’s fine too. 

The Ryuijin ii also features 380mm sleeved tubing comprised of thick rubber, to add durability and improve the visuals over the duller tube designs. 

All in all, we have a beefy, efficient radiator that will provide your 5950X with all the cooling it needs, and the inclusion of a hefty, high-flow water pump means your CPU will never be in short supply of cold water to cool it.

The Noctua NH-D15 stands tall against its competition, this air cooler even gives some lower-end liquid coolers a run for their money.

The design is certainly to a specific taste, but it’s the cooling potential that matters most when opting for a CPU cooler. 

The size can be an issue if you’re wanting to build in a smaller form factor case, with extra clearance needed for the two giant heatsinks and accompanying 140mm fans. Noctua does offer an ‘S’ variant, which is significantly smaller for those that lack the space for the larger model, without compromising on cooling effectiveness. 

Overall, if you can fit this into your PC, it’s one of the best air coolers on the market to date. The max noise sits near 24.6dB and with a max RPM of 1500, offering high-end air cooling performance with low noise levels. 

Pros
  • Solid thermal performance
  • Excellent acoustic performance
  • User-friendly mounting system
  • Outstanding build quality
  • Comes with (2) 140mm fans
Cons
  • Relatively expensive
  • Hefty size

Final word 

Whether you’ve just got a 5950X or you’re just looking for a new cooler, there’s no denying it’s an absolute multicore beast. All this performance means the 5950X works up a sweat and needs some powerful cooling to keep it ticking over.

Our recommendation is the industrial-looking ASUS ROG Ryujin ii, its superior cooling performance coupled with its strong, bold, and industrial aesthetics shows it means business. 

You wouldn’t be disappointed picking up the Noctua, however, if air cooling is more your thing. The Noctua offers superior cooling performance at a very low noise level.
