These are our recommendations for the best CPU coolers for Ryzen 5900X and 5950X in 2021.
The Ryzen 5900X and the 5950X are the two latest flagship processors by AMD. Released in late 2020, the 5900X and 5950X feature 12 and 16 cores, respectively, and excel at every task you throw at them.
Before these two, Ryzen 3900X and 3950X were the AMD’s best consumer-grade CPUs. As good as they were in productive apps, Intel managed to get a slight lead in gaming due to the higher boost clock speed and better single-core performance.
Best Cooler For Ryzen 9 5900X And 5950X Review Guide
As a result, AMD made several improvements in Ryzen 5000 series, such as double L3 cache accessible per core, lower latency, and high clock speeds.
It results in 5900X/5950X comprehensively beating Intel offerings by a good margin – in both gaming and productivity.
Not only that, they offer far better performance than their predecessors Ryzen 3900X/3950X, despite featuring the same number of cores and threads.
All we cay say is that AMD has done a pretty good job.
But for a balling rig featuring either of these processors, it is crucial to find the right CPU cooler. A cooler that can quickly and consistently dissipate high amounts of heat, play well with the clearances involved in your case and RAM choices, and match the overall aesthetics you are going for.
Here, we take a look at four excellent cooling options at different price points that can be the perfect foil for your Ryzen 9 5900X or 5950X.
1. Be Quiet! Dark Rock Pro 4
Best Air Cooler For Ryzen 9 5900X And 5950X
- Two virtually inaudible silent Wings PWM fans
- Funnel-shaped frame of the front fan for high air pressure
- Achieves only 24.3Db(a) at maximum fan speed
If you are looking to keep your system air-cooled through and through, the Dark Rock Pro 4 is a great place to start.
A lot of people swear by air cooling and the impact it has on the overall airflow inside your case.
For such use cases, the Dark Rock Pro 4 is a large, sturdy, and efficient cooler with an understated look and quiet operation.
The cooler incorporates seven high-performance heat pipes made from copper to achieve around 250W TDP of cooling.
The specially designed cooling fins are optimized for high airflow and maximum surface area with a wave contour and small dots on the surface.
The black coating on the entire area uses ceramic particles to further aid heat transfer.
The double-tower layout uses two aluminum heatsinks and two fans—a smaller 120mm at the front and a larger 140mm in the middle position.
These Silent Wings fans are optimized for both airflow and static pressure.
One standout feature is the attention to detail that brings excellent RAM compatibility and clearance even for a cooler this large.
The front fan is smaller and raised with special cutouts in place to prevent clearance issues.
This way, you can install this cooler even in cramped cases.
There is also an option to add a third fan in the rear to achieve even more airflow.
The funnel design of the front fan increases static pressure and both fans use a decoupled mounting for less vibration.
The fans are exceptionally quiet, even if you set them at 100% in PWM mode.
With the excellent thermal performance and quiet operation, this can be a perfect choice for a workstation PC or a minimalist gaming setup.
- Almost silent operation
- Great cooling
- Versatile fan config
- Large and unwieldy

Best CPU Cooler For Ryzen 9 5900X And 5950X – FAQs
Below are some of the common questions people ask about the Ryzen 5900/5950X CPUs and their coolers.
Does Ryzen 9 5900X And 5950X Come With A Stock Cooler?
No. In Ryzen 3000 lineup, you get a stock cooler with all processors except the 3950X. The Ryzen 5000 Processors, though, don’t offer such coolers except the 5600X.
Does Ryzen 9 Processors Need Liquid Cooling?
No, it’s not mandatory.
The Ryzen 9 processors are flagship models, which means while it’s good to pair them up with an AIO cooler (especially if you intend to do overclocking later), you will get almost similar results with a high-end Air cooler, such as Be Quiet! Dark Pro 4.
Is 240mm AIO Enough For 5900X And 5950X?
Yes, good quality 240mm AIO cooler will be good enough to handle the load for both of these CPUs.
How Long Will An AIO Cooler Last?
With proper care, an AIO cooler can easily last 5-7 years. Some manufacturers rate their AIO pump’s life expectancy to as much as 70,000 hours.
Is Custom Loop Better Than AIO?
It depends on different factors. Custom Loops are visually more pleasing and offer higher performance but a higher price. On the other hand, AIO coolers come with more reliability and require less maintenance than custom loops.
Do You Have To Refill Liquid Cooling?
If it’s a custom loop, then yes, you require periodic refilling and maintenance of other sorts. AIO coolers don’t need such refillings, and that’s why they’re called closed-loop coolers (CLC).
