The Ryzen 9 5900X is an outstanding comprehensive CPU that only comes second to the well-known 16-core R9 5950X. This CPU is among the top consumer choices for premium refresh rate gaming and for users who don’t need the best-in-class productivity performance of the 12900K or the 5950X. The CPU features 105W of TDP and a base clock of 3.7GHz with a boost speed of 4.8GHz. This exceptional power-optimizing capacity allows it to pair up perfectly with a large number of cooling solutions. 

Due to such an enormous supply of CPU coolers available on the market, ranging from air and liquid to AIO (All-in-one) types,  picking the Best CPU Cooler for AMD Ryzen 9 5900X can be a daunting task. However, this is exactly why you are reading this article as we have a team of experts who will be of great help to you.

1.  DeepCool AS500

If you want the Ryzen 9 5900X to run at stock clocks or with an undervolt, consider the DeepCool AS500. Although its thermal performance isn’t as great as the NH-D15 and the Assassin III, that isn’t too big a deal to explain their price difference. 

The AS500 is currently a better choice for the price it is worth. Aesthetically speaking, it is designed beautifully with delicate RGB lighting, besides its excellent performance. It also weighs more than 1 kg (roughly 2.2 lbs), which is heavier than its single-tower cousin.

Another great feature of the AS500 is that it runs very quietly thanks to a 140mm fan. Although you can get two fans with the AS500 plus, the latter is not quite scarce to be found. Plus, they don’t have much of a difference in performance. The only drawback is that it is up to 164 mm high, which is too much for a single-tower cooler. That means the AS500 probably won’t fit mid-tower cases.

2.  Noctua NH-D15

If you want an air cooler that runs even the most quietly and also delivers the best performance, then consider buying the Noctua NH-D15. For such reasons, this cooler is designed specifically for high-ranking CPUs and also makes outstanding thermal performance.  

Additionally, the NH-D15 can also deal with an overclocked 5900X without any problem. The biggest shortcoming that it has is that its size is too large, especially if you have an mATX or a smaller-sized mid-tower case. The RAM space is also relatively limited. If the NH-D15’s color palette isn’t really your thing, you can go for the plain black version.

3. DeepCool Assassin III

Similar to the NH-D15, the DeepCool Assassin III is a great alternative. The only difference is that it’s slighter louder than the Noctua, but their thermal performances are both the same. Once again, its major problem is its big size and tight RAM space, which doesn’t allow it to fit into smaller cases. If you truly want this air cooler, make sure you study the best low-key RAM kits as it’s highly likely that you’ll find it useful.

4. Scythe Big Shuriken 3

A CPU such as the Ryzen 9 5900X and slim form factor coolers aren’t typically the best combination. Despite its strength, the SFF air cooler is not designed to run a 12-core monster like the 5900X. 

However, the best option you can find on the market for an SFF rig is the Scythe Big Shuriken 3. It is considered the best low-profile CPU cooler currently. This SFF radiator should have enough capacity for a 5900X used in gaming to run at a stock clock.

The CPU temperature could be increased above the thermal throttling threshold by larger volumes of work. Nevertheless, if you lower the CPU temperature a bit and reduce the PPT, it should be able to operate safely even under heavy workloads with a performance loss of a single digit.

5. Arctic Liquid Freezer II

Switching to AIO coolers, we have the best price-to-performance AIO cooler here that is the Arctic Liquid Freezer II. There are two versions: the 280mm and the 360mm, of which the former is more suitable for a CPU with 12 cores. 

If you want something to run silently or have a plan to test the OC limits of the 5900X, then consider the 360mm version as this AIO cooler will mostly run at very low RPMs.

Overall, the Arctic Liquid Freezer II is regarded as the top-choice AIO cooler for the 5900X and the best AIO cooler that is very economical at the same time. Its price is set lower than most of the AIO cooling systems available on the market.

These are the most commonly asked questions related to the Best Cpu Cooler For Amd Ryzen 9 5900x.

1. Is the Ryzen 9 5900X equipped with a stock cooler?

The bad news is AMD doesn’t offer a ready-to-go thermal solution , so you’ll have to pick a separate cooler to cool things down. 

2. Does the Ryzen 9 5900X heat up too much? 

Both yes and no. AMD has admitted that the processor might experience overheating problems, with temperatures reaching up to more than 90 celsius degrees. They have announced that these are common temperatures for this CPU and won’t influence the life cycle of the processor.   

3. Do you need a replacement CPU Cooler for the  Ryzen 9 5900X?

Absolutely yes. As stated above, it can get very heated with this type of CPU. This explains why a replacement CPU cooler is definitely needed to maintain and raise its performance and durability.

4. Which kind of cooler works best for the Ryzen 9 5900X? 

This question entirely depends on your personal preferences as air, liquid, or AIO CPU coolers have just about the same performance level. Speaking of liquid coolers, you run the risk of damaging your internal components if a malfunction or water leakage occurs. Meanwhile, with air coolers, insufficient thermal paste installation and inappropriate cooler seating may cause mediocre cooling performance. Although AIO coolers can give you the best of both worlds, they come with a higher price than a regular durable air cooler. So the choice is always in your hands.
