Air coolers have been DeepCool’s focus as of late, and the company has been on a tear lately introducing very effective cooling products to the market. This time, DeepCool has unveiled their AK620 CPU cooler, which boasts amazing characteristics on paper and delivers effective cooling while also allowing for optimal airflow.
The DeepCool AK620 is a Twin-Tower cooler that measures around 160 millimeters in height. For improved conduction of heat, it has six heat pipes with nickel plating and solder connections to the base plate. Aside from that, it includes two fans of the same size, each measuring 120 millimeters and equipped with fluid dynamic bearings. These limit the amount of noise produced by the fans without sacrificing performance. The fans have a PWM speed that ranges from 500 to 1850 RPM, and the overall noise output of the cooler is just 28 dBA, which is quite low for a cooler of this size. In addition, the airflow from the fans is 68.99 CFM, and the air pressure is 2.19 more.
In terms of compatibility, this large cooler has a width of 138 millimeters, which means that ram clearance may be a problem; despite this, it is not too difficult to move the fan to the other side of the cooler. The CPU cooler has a height of 160 millimeters, which enables it to be installed in almost any case you choose. Additionally, the DeepCool AK620 features a square design on both sides, which assists with the airflow of the product as a whole. It’s also important to note that this particular cooler does not have any RGB lighting of any kind. The design was purposefully kept simple and classy by DeepCool.
Incredible thermal performance may be expected from the DeepCool AK620. The Ryzen 9 3900x can run in its factory settings while the DeepCool AK620, which has a TDP of around 260 watts, is able to keep it cool without any issues. Even while operating under heavy load, the 120mm fans continue to function quietly while still performing very well. There is just a little audible disturbance. It is possible to utilize the DeepCool AK620 as an excellent air cooler for first-time builders, and it is also possible to suggest it for use with CPUs that are not intended for gaming. Although the DeepCool AK620 offers remarkable performance in comparison to its cost, it is not at all a low-cost air cooler, coming in at roughly 70 dollars in the United States. In addition to that, ram clearance is another potential problem with the DeepCool AK620, as was discussed before in the paragraph. Additionally, the third set of fan clips would have been a welcome addition to this CPU cooler if it had been included. Adding one more fan would have been helpful in making this cooler a total overkill for its intended use.
DeepCool is one of the leading manufacturers of air cooling solutions, and they have been making a name for themselves over the last decade with their highly efficient CPU cooling solutions. DeepCool’s AK620 is a high-end air cooler with a unique design; it also features two RGB LED fans, which provide additional cooling and lighting options. The DeepCool AK620 is a good air cooler for the Ryzen 9 3900x. The cooler is based on a 3-phase power supply design and has an aluminum heat sink. It has a maximum fan speed of 2200 RPM, which is quite fast and should be enough to cool the processor.

The high-performance air coolers manufactured by Noctua are available at a range of pricing ranges and are compatible with a variety of computer systems. It was the first company to create an efficient method of keeping a computer’s central processing unit (CPU) cool using fans of a hue other than the customary brown. This fact surprised many customers. On the other hand, some people find it distracting to see a brown fan sitting within a black-themed computer setup. As a result, Noctua has started, over the course of the last several years, to transform its already-existing products into the black-themed portfolio of coolers known as Chromax. Since we are seeking for the most effective air cooler for Ryzen 9 3900x, we will investigate the Noctua NH-U12A, which is one of the most effective coolers that Noctua has to offer.
The Noctua NH-U12A was first released with brown fans with the Noctua logo; however, customers expressed interest in purchasing an all-black edition of the cooler. As a result, after years of pleading with Noctua, the company has finally responded by releasing the Noctua NH-U12A in an all-chromax black finish. Let’s find out whether it was worth our time to wait for it.
Further investigation reveals a Noctua NT-H1 thermal compound, regarded as one of the best on the market. You also receive a Y-splitter PWM fan cable, which allows you to connect both fans to a single fan connector if your Ryzen 9 3900x motherboard does not have two CPU fan headers. Furthermore, the package includes a low noise adaptor connection for running the fan at a reduced speed, however this extra is unneeded for some individuals since these fans are among the quietest on the market. Finally, the black-themed CPU cooler is paired with the highly sought-after NF-A12x25 PWM fans for a twin fan configuration. This gigantic cooler is as large as the Noctua NH-D15/S, but it is not as powerful as the Noctua NH-D15/S since it keeps the cooling power of a 140-millimeter fan in a 120-millimeter. It also includes the popular NF-A12x25 PWM fans for a twin fan arrangement.
In terms of specs, it is quite comparable to the ordinary Noctua NH-U12A except for the addition of a black paint job all over the product. Chromax Noctua NH-U12A. Because it does not extend towards the RAM sticks, Black is 158 millimeters tall with and without fans. The CPU cooler is 125 millimeters broad and 58 millimeters deep, with a TDP of 150W. Surprisingly, the heat sink is denser than any other Noctua model of comparable size. It weighs 1.22 kg more than the Noctua NH-D15/S with both fans attached.
Noctua built them such that they stay close to the fan’s frame, allowing less air to escape through them and creating superior air pressure towards the heatsink. This is how these fans make a shockingly low amount of noise even at full speed, estimated at just 22.6 decibels. The rating is reduced to 18.8 decibels with the inclusion of the low noise adaptor. As a result, the low noise adaptor was judged superfluous.
Furthermore, the fans are rated at 2000 RPM, which is reasonable for dual-tower CPU cooling. In terms of stress detection, the 4-pin PWM y-cable included enables the fan to automatically detect whether or not the CPU is becoming hot. Under stress or idle, the fans exhibit no signs of squeaks or wear and tear, making them perfect for overclocking. The nickel-plated mirror finish base at the bottom is reflective enough to provide a soft light on your face. The seven black-painted heat pipes are soldered to the metal finery immediately.
Overall, we like the NH-U12A Chromax. Black is a one-of-a-kind serial murderer. I don’t mind the absence of RGB since the cooler seems more stealthy in the dark black hue. Noctua’s supplementary covers are also quite appealing since they contribute to the minimalistic appearance that most people strive for. We can’t complain about the pricing since this small cooler is practically silent and runs like a beast. Finally, if you don’t like the notion of an AIO liquid cooler and don’t mind spending money, this is the Best Air Cooler For Ryzen 9 3900x.

The well-known Noctua need no introduction since it has already been discussed. However, it would be a pity to proceed without first appreciating the brand. Noctua, known for developing a broad range of coolers, strives to outperform and dominate the CPU cooler industry, and it is successful in responding to varied customer needs. Some people want a large, high-performance cooler, but others are ready to spend their money wisely on a cooler that will do the job. Because Noctua caters to consumers on a restricted budget, it has chosen to release a low-profile CPU cooler, the NH-L9a.
The Noctua NH-L9a-AM4 is an enhanced version of the NH-L9a created exclusively for the AMD Ryzen platform. The previous standard edition of the Noctua NH-L9a-AM4 was finished in Noctua’s well-known wood-brown hue. Many folks want a low-cost cooler with an all-black look. Noctua has totally renovated its low profile cooler in an appealing black dress and unveiled the Noctua NH-L9a-AM4 chromax.black, knowing the business is recognized for providing a high-quality black variation of their current goods.
When we look at the Noctua NH-L9a-AM4 specs, we see that it is just 37 mm tall, 114 mm wide, and 92 mm deep. Because of its very compact size, it offers unfettered RAM clearance compatibility. This enables it to fit into any of the smallest SFF cases presently available. This low-profile cooler employs just two copper-made heat pipes, each with a diameter of 6mm, for heat dispersion. These pipes make direct contact with the cooler’s base plate, forming a U-shaped run through the fifty-three black metal fins. When seen from the side of the cooler, the heat pipe ends, which are equally polished and completed, seem somewhat. This is how it seems.
When it comes to fans, the NF-A9x14 Chromax.Black HS-PWM is crucial since it provides the high-quality features that Noctua is known for. Among these characteristics are flow acceleration channels on the blade, stepped intake design, inner surface micro-suction, and the now-famous SSO2 bearing, all of which increase airflow management. With all of these characteristics, it delivers an airflow of 33.8 CFM (24.03 CFM with LNA) and a pressure of 2.11 MM/H2O. Fortunately, this fan is PWM compliant and operates at the speed specified by the motherboard. This 92mm fan has a 14mm thickness but a minimum speed of 660 RPM and a maximum speed of 2500 RPM with a TDP of 95W. The fan has a maximum sound rating of 23.6 dBA, which is reduced to 14.8 dBA when the low noise adaptor is used.
This low-profile cooler is an excellent value for the money. Because it is practically shorter than the motherboard’s VRM heatsink, it enables 100 percent RAM clearance. It is rather quiet and delivers excellent airflow with all of the fan functions available from Noctua. It is far more difficult to complain about a cooler at this pricing point. RGB, on the other hand, is something that consumers may want to have in a little cooler. Aside from that, the 95W TDP is lower than other coolers, limiting the ability to readily overclock this cooler.
Finally, the NH-L9a-AM4 chromax.black includes a number of characteristics that make it a good choice for customers on a restricted budget. It is a fantastic small-factor cooler that can manage a powerful CPU, such as the Ryzen 9 3900X, in both gaming and most tasks. The absence of RGB compliments the dark aesthetic and is not very necessary. However, because of the low TDP, overclocking may be an option that customers choose to ignore, which may frustrate certain users. In conclusion, NH-L9a-AM4 chromax.black is the best budget CPU cooler for Ryzen 9 3900X if you want a low-profile cooler with quiet and performance.

Arctic is a well-known brand that produces some of the finest liquid coolers on the market. They are also well-known for their high-quality thermal compound. They’ve made a wide range of goods, including air coolers and other liquid coolers. Today, we’ll look at its most well-known cooler, the Arctic Liquid Freezer II in the 240mm model, which is suited for practically every CPU.
This newest AIO cooler has RGB lighting that is completely adjustable and compatible with a variety of RGB softwares such as Arctic’s addressable RGB system, Asus Aura Sync, MSI Mystic Light Sync, RGB Fusion 2.0 Gigabyte, and Asrock Polychrome Sync, to name a few.
The Arctic Liquid Freezer II boasts a 240mm radiator with an amazing 38mm thickness, as the label says. The radiator seems to be sturdy and well-made, and it gives the impression of a high-quality product at first sight. The pump unit, without a doubt, is the star of the show. The pump unit is outfitted with a little VRM fan, much like a future one-eyed robot or just an astronaut. This 40mm small VRM fan has a speed range of 1000 to 3000 RPM and serves the useful goal of discreetly cooling the VRM on your motherboard or comes in handy in the event of insufficient airflow. It follows a rigorous cable management guideline by employing just one cable method, with a single PVM spinning the fan and a three-pin A-RGB keeping everything lighted.
If the little pump fan irritates you in any way, just look at the bottom of the pump unit and unhook the fan. While you’re rotating the pump unit, have a look at the copper-plated base. Arctic claims to boost efficiency and reduce power usage while making things quieter. By comparing these claims to the specs, we may be able to gain a good image of what Arctic has to offer. The pump speed varies from 800 to 2000 RPM while requiring just 0.5W to 2.7W of electricity. Aside from that, the pump is scarcely audible, so Arctic honors their terms.
Moving on to the fans, Arctic picked two of the Arctic P12 PWM RGB 120mm fans with rubber pads to dampen vibrations. These fans have so much power that they can compete with some of the market’s 360mm AIO systems. Despite fan speeds ranging from 200 to 1800 RPM, these fans function effectively while maintaining a relatively quiet profile of roughly 32.6 dB(A). The maximum airflow is 48.8 CFM, and the maximum static pressure is 1.85mmH20. Arctic has doubled the amount of rubber bumpers and added fluid dynamic bearings, all of which assist decrease vibrations by up to 95%.
The Arctic Liquid Freezer II 240mm is an excellent all-arounder. Despite their effectiveness, the fan and pump are rather quiet. The VRM fan on the pump unit, on the other hand, may seem unneeded to some, but the ability to disconnect it makes it better. The plastic cover on the radiator and pump unit might have been made of solid metal in the same gray color, adding to the CPU cooler’s durability. Aside from that, the Arctic Liquid Freezer II 240 is the Best AIO CPU Cooler for Ryzen 9 3900x.
