We would not call Scythe the most recognizable brand on the planet. However, they make award-winning coolers.
In 2015, they earned an “Excellent” award from Hardware.info for their Fuma radiator.
Previously, they won the Best Cooler of The Year in 2014 from the same publication. While they may not be as famous as the other brands on this list, you can still expect some exceptionally crafted coolers from them.
The Scythe Mugen 5 Rev.B is exemplary of this fact.
The first thing you need to know about it is that it’s a tower cooler. Thus, you should make sure that you have enough clearance inside your rig before you purchase it. Just how much clearance do you need though?
The cooler measures at a height of 154.5 mm, a width of 130 mm, and a depth of 110 mm.
It weighs just under a kilogram (890 grams to be exact). Despite its size, it has extremely good RAM compatibility, although it depends on your motherboard as well.
Nevertheless, the radiator fins have a cut out to ensure that if it does encroach on the RAM sections of your motherboard, you can install your RAM underneath.
Not only is this cooler compatible with AMD AM4 socket (for Ryzen 7 5800X processors) but it can also be fitted to most of the latest Intel sockets too.
This includes LGA 775,1150,1151,1155,1156, ,1200,1366,2011(V3), Square ILM, and 2066 Square ILM. The Scythe Mugen 5 Rev.B is relatively easy to install. It comes with a spring-loaded mounting system.
Connected to the copper base plate exist six 6mm heat pipes, prime for effective heat dissipation. The fan that sits in front of the radiator seems standard. It’s a 120mm ball-bearing fan.
If you feel that this won’t provide your CPU with enough cooling, you can add an additional fan using the provided fan clip.
Overall, the Scythe Mugen 5 Rev.B delivers excellent cooling at a reasonable price. If you’re looking for a budget tower cooler, then we highly recommend this entry.

Deepcool has been producing quality computing peripherals and accessories since the late ’90s. It should not be a surprise to see one of their products on our list of the best Ryzen 7 5800X coolers.
Technically, the Assassin III falls under the Deepcool Gamer Storm product line which consists of gaming cases, cooling solutions, and other game-orientated accessories.
Thus, it should be understood that the Deepcool Assassin III is geared towards gaming cases. The new Ryzen 5000 series was created for gamers in mind, however, it would not go wasted in a professional set up. This is true for the Deepcool Assassin III.
As the name implies, it’s the third entry in Deepcool’s Assassin series. Much like its predecessor, the Assassin II, the Assassin III is built like a giant tower cooling sandwich.
However, where the Deepcool Assassin III had red fans, the Assassin III has uniformly black fans. This means it will cooperate with the color scheme of most builds.
The Deepcool Assassin III essentially consists of two coolers connected in a tower cooling setup. It’s made up of two fans and two cooling blocks/radiators.
The fans are made with Deepcool’s (Gamer Storm’s) patented double-layer fan blade design, held to the radiator with an obsidian-like spoiler. The fins on the radiator are nickel-plated.
The base plate is built primarily from copper and has a convex mirror finish. Connected to it are seven heat-pipes.
That’s one more heat-pipe than the Scythe Mugen 5 Rev.B. Since the Assassin III is a tower cooler, you will need to ensure that it has enough clearance in your rig. Its dimensions are as follows: 161×140×165 mm.
Overall, this may be more expensive than the previous entry but it objectively outperforms it. If you can afford it, we highly recommend the Deepcool Assassin III.

Nevertheless, it’s fairly silent and cannot be heard over the rest of your system’s noise. The pump on this cooler is part of the block. The impeller can be seen near the cold plate.
To neaten up the setup, Arctic has chosen to run the Liquid Freezer II 240’s fans through the tubes that connect to the base plate. Much like the previous entries on this list, there are no fancy RGB lights to speak of on this cooler.
That’s one of the reasons this is one of the most affordable all-in-one liquid cooling solutions. This cooler uses a sealed water loop. You don’t have to worry about refilling it or adding anything to it.
Overall, you’re paying purely for the ARCTIC Liquid Freezer II 240’s performance when you purchase it. It can be said that it goes above and beyond its price tag in terms of performance.
Furthermore, you can always replace its fans, if you want something more colorful in the future. Nevertheless, this entry is definitely one of the best value for money 240mm AIO Coolers.

As with the ARCTIC Liquid Freezer II 240, this cooler works with a closed loop and requires no maintenance.
Once you install it, you won’t need to worry about refilling or changing out the liquid.
Installation is relatively easy. However, the tight screws on the radiator will require you to use quite a bit of dexterity and strength to look them into place.
In addition to this, the wires can be a little tricky to route and work with.
The Corsair iCUE H115i RGB Pro XT is the best-looking cooler on this list. It’s quiet, customizable, and well built. The only thing that may discourage you from purchasing it is its price tag.

Frequently Asked Questions
Below are some popular questions people ask regarding Ryzen 5800X and CPU coolers, with our answers.
Does Ryzen 7 5800X Come With A Cooler?
No, the only Ryzen Zen 3 processor to come with a stock cooler is Ryzen 5 5600X.
Does Ryzen 7 5800X Come With Thermal Paste?
Thermal paste usually comes pre-applied on the stock cooler of a CPU. Since Ryzen 5800X doesn’t come with any stock cooler, there’s no thermal paste out of the box.
Air Vs AIO Cooling For Ryzen 7 5800x
You can take whichever route you like. AIO coolers look more pleasant but will cost more to provide the same level of performance as high-end air coolers.
They generally transfer heat more efficiently than air coolers and run quieter.
Air coolers cost less than AIO coolers for roughly the same performance and have a comparatively easier installation process. Their main disadvantage is that they can’t always fit inside your chassis, especially if you got an SFF PC build.
That’s why it’s better to check the compatibility of such coolers with your case before making a purchase.
Can A CPU Die From Overheating?
Overheating can be harmful to generally all of your PC components, and the same is the case with CPU. Overheating can make your system unstable and shut down.
Even if it doesn’t die immediately, overheating for a long period can reduce the lifespan of your CPU.
Can You Install A CPU Cooler Without Removing The Motherboard?
Yes, you can. Any good aftermarket PC chassis comes with cutouts through which you can access the motherboard from both sides and remove the cooler.
Is 70° Safe For CPU?
Yes, if 70° is the your CPU temp under full load, it’s perfectly fine. CPUs are designed to go as high as 100°.
After this point, you will start to feel throttling. Read our guide on lowering the CPU temperature for more info.
