The new Ryzen Zen 3 CPUs offer groundbreaking gaming performance and a great headroom for overclocking. Ever since their launch, enthusiasts are all geared up to upgrade their builds.
While Ryzen 9 5900X is all about gaming performance with 12 cores and 24 threads, Ryzen 5950X bruises in multi-core workloads, featuring 3.4 GHz base clock speed and 4.9 GHz turbo clock speed, making it an ideal choice for content curators. And on top of that, both these CPUs now support PCIe 4.0, which surely translates into lag-free gaming and smooth functionality due to the higher bandwidth of the new PCI Express mode.
Even though these CPUs bring a lower TDP (Thermal Design Power) of just 105W but since they are so powerful and are able to run at high frequencies, it’s excessively hard to keep them cool. And the punch line here is that this time AMD has excluded a stock cooler or thermal solution for both Ryzen 9 5900x and 5950x.
If you’re among those enthusiasts who are either looking to upgrade or make a new build with Ryzen Zen 3 CPU, you’ll need an aftermarket cooler to ensure you can make the most out of the builds’ productivity and performance.
When it comes to aftermarket coolers, there are a lot of options in the market which makes it difficult to choose the best one for you. If you want to read more about the best CPU Coolers for a variety of builds, be fore to check out OvrClock’s CPU Coolers category.

Noctua NHL-12S is the ultimate choice for low-profile SFF builds. It offers a quiet cooling performance topped off with great efficiency. It’s just 70mm tall and features a slim 15mm thick 120mm fan with outstanding effectiveness in heat dissipation.
It offers the same performance as the Big Shuriken 3 but with a better cooling performance at a marginal price difference. But with the sort of price you’re paying up for your processor, this price difference is quite reasonable. If you want it to operate in the stealth mode, make sure to add the low noise adopter.
The CPU cooler provides extended clearance underneath the fin stack for memory modules. With that said, we would not recommend overclocking your CPUs on this SFF cooler; however, if you do plan on it and don’t have space constraints in your mITX build, the cooler supports integrating 25mm thick fans.
Noctua NH-L12S also tags in a premium-quality thermal compound and a 6-year manufacturers’ warranty, making it an easy winner for the best low-profile CPU cooler for Ryzen 9 5900x and 5950X.
Best Silent Air Cooler for Ryzen 9 5900X & 5950X
Be Quiet Dark Rock Pro 4
|Noise Levels||13 – 24 dBA|
|Fan Speed (RPM)||1,200-1,500 RPM (at 100%)|
|Dimensions||5.4″ x 5.7″ x 6.4″|
|Compatible Sockets||LGA 1150, 1151, 1155, 1156, 1200, 1366, 2011(-3) Square ILM, 2066, and AMD AM2(+), AM3(+), AM4, FM1, FM2(+)|
Bringing an immense cooling performance of 250W, enough for even AMD Threadripper CPUs, Be Quiet Dard Rock Pro 4 offers nothing but pure cooling performance and silence! Even putting extreme loads on the CPU, you’ll hardly hear anything.
With two virtually silent-wing inaudible PWM fans, the CPU cooler integrates seven high-performance copper heatpipes blended around air-flow optimized cooling fins. The cutouts on the fins ensure even better RAM compatibility and the two aluminum heatsinks offer excellent heat dissipation.
From an aesthetic point of view, since most of the motherboards these days come with a black-themed PCB, the cooler will surely add a nice vibe with the dark treatment.
One thing to note here is it’s a tower CPU cooler, and the size is pretty much the same as NH-D15, so the installation can be troublesome for some noobs builders.
Best RGB AIO Cooler For Ryzen 9 5900X and 5950X
Corsair H115i RGB Platinum
|Noise Levels||10 – 36 dBA|
|Fan Speed (RPM)||2,000 RPM (Maximum)|
|Dimensions||1.1″ x 5.4″ x 12.7″|
|Compatible Sockets||LGA 1200, 1150, 1151, 1155, 1156, 1366, 2011, 2066, and AMD AM4, AM3, AM2, sTRX4, sTR4|
Corsair H115i RGB Platinum is not just about the acoustics, the performance of this cooler in thermal dissipation is on the same par with many top-of-the-line AIO coolers, coming narrowly close to NZXT’s Kraken X62.
H115i RGB Platinum comes filled with coolant in a closed loop and the AIO cooler renders immense cooling performance with its two 140mm RGB-illuminated fans in correspondence with a 280mm radiator.
The PWM regulator on these fans automatically adjusts the speed of both fans. And even more, you can adjust the speeds of the fans and pump RPM and even customize the RGBs using the Corsair iCUE software.
The installation of the cooler seems a breeze with snap-fit mounting brackets that slide around the water block instead of using screws seen on traditional coolers.
But if you’re a performance enthusiast looking to maximize overclocking potential, you’re better off spending a little more and get the Corsair iCUE H150i Elite Capellix. The cooler has immense cooling potential with three PWM fans and using the zero PWM fan profiles, the cooler automatically turns off the fans at lower temperatures.
Best Silent AIO Liquid CPU Cooler for Ryzen 9 5900X & 5950X
Fractal Design Celsius S36
|Noise Levels||32 dBA (Maximum)|
|Fan Speed (RPM)||500 – 2,000 RPM|
|Dimensions||5.7″ x 7.0″ x 18.6″|
|Compatible Sockets||LGA 1200, 1150, 1151, 1155, 1156, 1366, 2011, 2011-v3, 2066, and AMD AM2, AM2+, AM3, AM3+, AM4, FM1, FM2, FM2+, TR4|
This was a tough decision to make because when it comes to silent cooling performance there’s no match for Corsair Hydro Series H150i PRO RGB 360mm. But paying such an extortionate price for a CPU cooler when Fractal Design Celsius S36 Prisma does the same job with half a price tag certainly makes this cooler the best silent AIO cooler for Ryzen Zen 3 builds.
The three dynamic x2 PWM fans feature automatic speed control and one of the best silent operations while the 360mm radiator covers an extended surface area for thermal dissipation during those rugged and extensive overclocking sessions. The radiator comes with a pre-applied thermal paste and fitting is pretty straightforward with traditional threads.
Being a no-frills silent cooler, Fractal has excluded an RGB light show. However, the cooler is certainly a sweet spot if you are just after a silent top-notch cooling performance with no strings attached to the aesthetics.
Best 280mm AIO Cooler for Ryzen 9 5900X & 5950X
ARCTIC Liquid Freezer II 280mm
|Noise Levels||~22.5 dBA|
|Fan Speed (RPM)||200 – 1,700 RPM|
|Dimensions||1.5″ x 5.4″ x 12.5″|
|Compatible Sockets||LGA 15X, 2011-3, 2066 *Square ILM, and AMD AM4|
Arctic Liquid Freezer II may seem way down there with the price tag and spartan appearance but you should have no doubts about the cooling capacity of this cooler. This AIO cooler is quiet, really quiet.
Integrated with specially-designed diagonal fans offering maximum airflow, 38mm thick radiators with a high-fin density covering an increased amount of surface area, you should consider yourself lucky if you find’em in stock.
Both the fans and the pump on this cooler are PWM-controlled with automatic voltage transformation. So no matter if you’re planning to go hours on CS Go or go nuts on rugged overclocking sessions, the cooler can effectively adjust the fan speeds based on the workload.
However, if you plan on testing the limits on your Ryzen 9 5900X or 5950X, take a look at the 360mm version.

It all depends on what you’re planning to do with your build. If you’re going to use it for less-intensive applications and are comfortable with moderate temperatures or are using a high airflow case, go for an air cooler. But if you’re planning to squeeze some power in terms of overclocking, we’d recommend you to go for an AIO cooler.
No, both Ryzen 9 5900x and 5950X do not come with a stock cooler. However, there are numerous third-party coolers in the market that offer support for these processors.
Among various factors, you should always decide the specific use case for your build. If you’re planning for a less-intensive workload, you can go for an air cooler but if you’re looking towards overclocking your Ryzen Zen 3 build, you’re better off using an AIO water cooler. The second most important aspect is to ensure that the CPU cooler and its radiator has enough RAM clearance to be installed in your form factor and PC case. One last thing is to check the sound levels of your CPU cooler. Generally, the larger the fans, the quieter they are.
If you’re planning on using your PC build for light uses cases and are comfortable with higher temperatures an air cooler is enough. If you’re planning on overclocking your build and need some extra help on that front, then a liquid CPU cooler is exactly what you need.
So, the Ryzen 9 5900X can support up to 128GB of RAM, but generally 32GB is enough for gaming, and 64GB is really enough for every single use case.
Aside from the typical methods of using a high air-flow case, and keeping your room cool, there are few options available. Closing all non-critical processes and windows through task manager is another option, but buying a quality CPU Cooler is really the best bet.
