The Ryzen 7 5800X3D is one of the best CPUs available on the AM4 platform, that much is true but with the integration of a 3D V-cache comes increased thermal sensitivity. We need a cooler to be able to handle the heat, literally, so we have outlined the best coolers for the Ryzen 7 5800X3D.

The Ryzen 7 X3D, with its advanced 3D V-Cache technology, is a powerhouse that demands efficient heat dissipation to prevent thermal throttling and maintain peak efficiency. Because of this, it’s the best choice for games on the AM4 platform who want to save money.

If you’re looking to secure this CPU for yourself, then you’re going to want a CPU cooler to fully support it. There is a mix of both budget and not-so-budget-friendly performance options that would be a perfect pair with this particular CPU. Let’s jump right in.

The ASUS Ryujin III 240 is one of the best 240mm coolers on the market today, being the third iteration of the Ryujin, all of the kinks and hiccups have been ironed out, shaping a truly capable cooler. This cooler is especially effective at cooling the 5800X3D and then some, we know this because we reviewed this cooler using the 14600K as the benchmark CPU, and it cooled that CPU with no problem.

It’s worth mentioning, that the 14600K has a much higher TDP than the 5800X3D, (125W vs 105W). This doesn’t seem like a lot, but it can really make a difference, regardless, the Ryujin III didn’t struggle with the 14600K and it certainly won’t struggle now. This cooler is made with only the most high quality of components, and thermally efficient materials. Including the new 8th-generation Asetek pump.

It’s hard to find a 240mm AIO that keeps the 14600K as cool as this cooler does, the performance is so good in fact that you would be forgiven for thinking that this was a 360mm

PC Guide

If you want a CPU cooler with an LCD screen that can display system health information, then the Ryujin just might be the CPU cooler for you. With that being said, you aren’t limited to just system information on this full-color LCD. You can display a funny image, GIF, or something to spice up your PC build further.

The industrial aesthetic that the Ryujin brings makes it fit into almost any build without looking out of place, especially if you have some of the more bulky high-end components inside your system.

What users say

The Ryujin III has a rating on Amazon of 4.6 out of 106 reviews, with one verified purchaser stating “Keeps 14900k pretty cool” This speaks for itself really, doesn’t it?

The Noctua NH-D15, which we recently reviewed, is one of the best air-based coolers on the market. Whilst air coolers are generally less efficient at cooling than their AIO counterparts, they offer an affordable option and option that will pair nicely with the 5800X3D. The D15 features a dual fan setup with two main heatsink stacks, offering double the surface area and cooling potential of most air coolers on the market.

The Noctua cooler we’re testing today is certainly capable of keeping thermal throttling at bay, but the temperatures aren’t exactly AIO level, of course, that makes sense, given the fact this CPU cooler isn’t an AIO

PC Guide

With this Noctua cooler, you get the basic foundation of a CPU cooler, there’s no fancy screens to be had here, it’s a bare-bones cooler but cooling is something It does very well. Driving almost all of the cooling process are the Noctua NF-A15 140mm fans, which can move air in volumes at a lightning-fast pace.

What users say

The Noctua NH-D15 has a 4.7 rating out of 5 on Amazon, based on 11,807 reviews of the product, which if the sales alone are any testament to this cooler quality, says that this is a very widely revered product. One user went as far as to say “I replaced a 3-year-old AIO liquid loop with this and I just wish I’d done it sooner. It’s MUCH quieter and both my idle and stress temperatures have decreased by a good amount. It is definitely a chunky boy but it’s actually really straightforward to install”.

The Corsair H150i LCD may seem like overkill for the 5800X3D specifically, but the cooler you keep your CPU, the longer it should last. So really, this is just an investment into the longevity of your hardware, and with this cooler rated to last around 6 years (as the warranty states) it’s likely this AIO will see a couple of your CPU choices.

If you need a CPU cooler to titillate the need to plaster memes all over the inside of your PC, or you’re more sensible and want to display system information to keep better track of your PC, then this cooler might be the one for you

PC Guide

Maybe you want to go ahead and shoot for the 7000 series, or the upcoming 9000 series on your next CPU, this cooler will take you there. Corsair is well known for its quality and performance in the cooling space with years in the business of keeping PC components cool. This is reflected heavily in our Corsair H150i LCD review.

Not to mention, you have a 480 x 480 LCD screen to display real-time system information, fed to you by iCUE, Corsair’s proprietary monitoring and control software. iCUE is relatively easy to use and handles all of the updates your cooler will need throughout its life. Yes updated, coolers need updates in 2024.

What users say

The Corsair h150i LCD has a 4.3 rating out of 1,033 reviews, another astonishing sales record. One user, in particular, had this to say about this Corsair CPU cooler: “This bad boy is like the superhero of CPU coolers – keeping your processor chill while looking cool with its LCD display”.

Features and considerations

Here we outline some considerations that you should take when selecting a CPU cooler, it doesn’t matter if the cooler is for the 5800X3D or any other CPU, these considerations remain mostly the same. Apart from the cooling demands of the CPU, that’s about the only variable.

Efficiency and performance

When selecting a CPU cooler for a Ryzen 7 5800X3D, cooling efficiency is the top priority. The cooler must be capable of handling the processor’s heat output, particularly under sustained loads like gaming or video editing. Look for coolers with a high TDP rating, which indicates their cooling capacity.

System compatibility

Another vital aspect is the cooler’s compatibility with your system. Ensure that the cooler fits within your case and doesn’t obstruct other components, especially RAM slots. Noise level is also a consideration; a quieter cooler is preferable for a distraction-free environment.

To screen, or not to screen?

Do you want your CPU cooler to have a screen? You have that option now, we’re living in the future and it’s starting to show. Having an LCD screen on your PC is entirely your choice and doesn’t really do anything to affect performance. Saying that there is some argument to be made that seeing your CPU temperatures constantly will help you take better care of it.

But, to be honest, most of us just end up putting cat pictures on the screen anyway.

Is the 5800X3D hard to cool?

Compared to more modern CPUs, not really. Even compared to the same generation of CPU, then why do we need a good cooler for it? Well, good question. Keeping the Ryzen 7 cool increases its longevity, as it does with any CPU. Not to mention the fact that the 3D V-cache inside the X3D is very sensitive to high temperatures. So it’s in your and the CPUs best interest to keep that CPU on ice.

Is a 240mm radiator enough for 5800X3D?

A 240mm radiator is more than enough to cool the 5800X3D, but the same job can also be handled by a good air cooler, such as the Noctua NH-D15 that we recommend in this article. The fact of the matter is that the X3D does not generate that much heat with its 105W TDP, but it’s better the cooler it is, thanks to the 3D Cache.
