When considering the best PC components, one simply cannot skip ASUS. In our list of the best Ryzen 9 3900x and 3950X CPU coolers, ASUS’s ROG Ryujin takes the spot. This 360 AIO CPU cooler is a heavy-duty next-gen beast that serves the most satisfying looks and incredible cooling performance.
The ROG Ryujin 360 is a flagship cooler that ensures top-notch thermal performance through its elegant and somewhat huge water pump and the obvious large fan set-up. When it comes to performance, the ROG Ryujin 360 is certainly our most favorite, and you can undoubtedly pair it with any high-end, even the ones far up the line, PCs, and you won’t be disappointed.
The 360 trio of Noctua Industrial PPC fans on the radiator ensures maximum airflow while maintaining the lowest noise levels possible. The 120-mm fans generate 122 m3/h of airflow at 2,000 RPM but still don’t go any far beyond 29.7-dB(A) of noise, which is the bare minimum for three fans running side-by-side.
The elegantly designed pump head is larger than most of the conventional pump heads, but it does bring with itself extra features to justify the size; the pump is equipped with a 60mm fan in its housing to circulate air beyond the processor, all around to the VRM and M.2 slots, to accommodate the most excellent thermal performance by working both as a powerful liquid cooler and as a traditional fan and heatsink set-up.
The ASUS ROG Ryujin 360 is one of the finest AIO coolers and the design is flawless. The dark black look with elegant RGB and logo placing brings about stunning aesthetics. It is the very first all-in-one cooler to have a fixed 1.77-inch LiveDash Color OLED that is used to display concise and useful PC information such as voltages, temperatures, frequencies, or fan speeds.
The range of personalization is also more than enough, so you can personalize the cooler however you like it, and get the best out of your bucks.

One of the most interesting choices to make was the Cyroig C7 G Graphene Edition. This super cool and small CPU cooler is an underrated pick because apparently, the single fan can only do so much cooling for such high-end PCs, but Cyroig C7 G does wonders in this case. It is specifically made for small form factor builds, say if you choose to build a Mini-ITX Ryzen 9 3900x you would have no trouble pushing it above and beyond the limits with the C7 G.
This compact CPU cooler is certainly far quieter than conventional coolers, and equally cool in every aspect. One of the most special detail about this cooler is that it is fully copper-made and covered in high-tech Graphene; Which if you are not aware is a metal-class material with an extremely high thermal conductivity level.
The cooling performance of the C7 G is high-efficient, so don’t skip it because of its high compatibility with small form factors, it will do just fine for bigger form factors, too. It gives in three different variants, but since Graphene is much more advanced and better in thermal conductivity, we choose it over the full-Aluminimum and full-copper variants.
This 47mm low-profile cooler can fit anywhere, there is “almost” in this case, and thus present in no PCI-e or RAM interference. The heatsink is copper made and there are quite a few 6mm heat pipes all in an effort to ensure that such a small cooler can prove to be highly efficient for high-end CPUs.
The single PWM fan on top comes with 11 curved blades that rotate at a speed of 600 – 2500 RPM. The noise is comparatively higher at around 30 dB (A), but it is only a single fan so it can’t be justified.
The deep black color all around, and the compact design make for very appealing aesthetics and the size attributes to the well-fitting design that looks good in every case. The heat pipes are very nicely incorporated into the heatsink and do not stick out at all.
Owning to its compactness, the price of this cooler is comparatively very low, and can easily be considered a budget high-end cooler in this case. With a TDP rating of 125 W, the C7 G, however, is just as good a choice as any other on the list.
|Radiator Size||97 mm|
|Noise Level||30 dB (A)|
|Fan RPM||600 – 2500 RPM|
- Compact Design
- Decent cooling performance
- Covered in High-tech Graphene
- Best for Smaller form factors
- Fair price
- Not very good for demanding rigs
- Comparatively louder
One of the paramount names among the cooling components manufacturers, the Cooler Master presents another compact and budget-friendly choice for the Ryzen 9 3900x and 3950x.
The Hyper 212 EVO V2 is another compact and budget-friendly choice that can give you the best possible thermal performance for your Ryzen 9 3900x without tying your hands on a budget. Compared to the previous model, the Evo V2 comes with a lot of improvement, including an Asymmetrical tilt to guarantee RAM Clearance, and revised brackets to make sure that the installation is easy and convenient. Just like the C7 G, it also consists of a compact heatsink and a single 120mm fan over it.
It is as compact as advertised and does not present any interference at all, in fact, its adequately small height gives it a 100% chassis clearance for any form factor. The X-vents design featured on every fin-blade presents a better and improved airflow mechanism by creating areas of high and low air pressure to identify where the increase in airflow would matter the most. The heat pipes are not only designed to give more clearance but also with direct contact technology to create a sleek contact surface area for maximum heat dissipation.
The SICKLEFLOW 120 fan comes with optimized fan blades that ensure incredible airflow and quiet operation.
The overall design, however, is not as sleek as the C7 G when it comes to compactness, but it surely is quite functional in every way. The aesthetics are still very much appealing, especially the fan looks elegant and give the overall cooler a minimalistic look which most of the users appreciate. Owing to its size, the price is also fairly low, and thus you can easily get the best value for your bucks with this one.
|Noise Level||8 – 27 dB|
|Fan RPM||650 – 1800 RPM|
- Incredibly compact
- Decent cooling performance
- Much quieter than previous models
