Typical CPU coolers can do standard thermal management jobs, but often fall short when it comes to quiet operation and peak cooling efficiency. This gap has prompted enthusiasts and PC manufacturers to turn to professional aftermarket solutions designed for their unique needs. The premium aftermarket cooling market is highly competitive, with brands competing to provide best-in-class thermal management solutions.
Today, we focus on DeepCool’s AK620 digital cooler, which is a well-known product in the field of high-end CPU coolers. At first glance, the AK620 Digital stands out mainly because of its integrated LCD screen. However, aesthetics aside, beneath the racy screen is a tower cooler that’s designed first and foremost to exceed the cooling needs of even the most powerful mainstream CPUs. It’s a big cooler: with a weight of 1.5kg and a height of 162mm, this is no lightweight radiator and fan assembly. All of this helps it stand out in a highly competitive market.
With that in mind, let’s take a deeper look at the AK620 Digital’s performance and its place in the aftermarket cooling world.

Packaging and bundling
The DeepCool AK620 Digital CPU Cooler comes in a stylish packaging with a simple cardboard box decorated with a stylish ribbon that adds an elegant touch. The cooler is securely packaged for easy shipping, comes in a nylon bag, and has foam padding to ensure it arrives in pristine condition. The back of the box highlights the key features and performance highlights of the AK620 Digital, giving potential buyers a concise overview of the benefits this cooler will bring to their PC setup.
When you open the package, you’ll find a small cardboard box containing the necessary installation accessories and basic, simple instructions. Have a syringe of quality thermal compound and a very basic screwdriver for installing the cooler. The included mounting kit is compatible with a variety of CPU sockets, allowing the AK620 Digital to work with a wide range of Intel (1700 / 1200 / 115x / 2066 / 2011) and AMD (AM5 / AM4) processors.
DeepCool AK620 Digital CPU Cooler
The DeepCool AK620 Digital CPU Cooler stands out among its peers with its powerful twin-tower design, integrating six premium 6mm copper heat pipes that transfer heat from the base to twin large fin arrays. The designer made the entire cooler black, sprayed each metal part with matte black paint, and used two all-black fans. The height of this radiator reaches 162mm, so compatibility is a consideration in a variety of situations. Weighing nearly 1.5 kilograms, the AK620 Digital is one of the sturdiest coolers on the market, highlighting the importance of removing the cooler from the motherboard during system relocation to prevent any potential damage.
DeepCool’s engineers designed the fin array to be quite dense. The front intake and rear exhaust form a checkerboard pattern, presumably to reduce aerodynamic noise, but the fins facing the center fan are completely straight. The front array has an extra notch for the digital display’s cable to pass through, improving cable management slightly. We also discovered that the top fin array had been scratched by some kind of tool, probably during the manufacturing process, but it was under the top cover, so factory quality control might have missed it.
The base of the DeepCool AK620 Digital is a basic metal block that holds the heat pipe and contact plate, while also acting as a support for the mounting bracket. Its top and mounting brackets are painted the same satin black paint as the rest of the cooler. The lowest part of the base, the contact plate, is made of solid copper, like any high-quality cooler today – however, DeepCool goes a step further and also electroplates the copper, creating a perfect mirror effect that won’t fade over time. oxidized over time.
One of the most outstanding features of the AK620 Digital is its high-quality fan. DeepCool uses two FK120 (DF1202512CM) fans with a Fluid Dynamic Bearing (FDB) engine and a custom frame with integrated shock-absorbing material. The fan has a maximum speed of 1850 RPM and features a high air volume/low pressure design with many small blades. This type of fan is typically used when minimal airflow resistance is expected. The fans lock onto the fin array via typical wire brackets, which also allow the mounting height of the front fans to be adjusted to facilitate access to the RAM modules if necessary. That being said, if you do need to move a fan, be sure to consider that raising the height of the fan will not only require a chassis with higher clearance, but may also incur a minor performance penalty.
The main feature of the AK620 is its digital display on the top, which is accessible via the JUSB motherboard connector. In addition, DeepCool installed A-RGB LED strips on the edge of the top cover, adding an extra touch of style. The operation of the digital display is separate from the RGB lighting, which is connected to the A-RGB controller header on the motherboard or third party. It requires the installation of a basic software driver, which offers very limited programming options, such as switching temperature units from Celsius to Fahrenheit. The display only reads and displays the CPU temperature and usage from the motherboard sensors, it does not affect the performance or functionality of the cooler in any way. The monitor only has one orientation, so the cooler needs to be installed in a specific orientation.
