The DeepCool AK620 Digital CPU Cooler Review: Big, Heavy, and Lit

Common CPU coolers work for standard thermal management but often fall short when it comes to quiet operation and peak cooling effectiveness. This difference drives enthusiasts and PC builders to specialized aftermarket solutions designed for their unique demands. The premium aftermarket cooling space is fiercely competitive, with brands striving to offer advanced thermal management solutions.

Today we're highlighting DeepCool's AK620 Digital Cooler, a notable entry into the high-end CPU cooler arena. At first blush, the AK620 Digital stands out from the crowd mostly for its integrated LCD screen. Yet aesthetics aside, beneath the sharp screen is a tower cooler that was first and foremost engineered to meet the cooling needs of the most powerful mainstream CPUs. And it's a big cooler at that: weighing 1.5Kg and 162mm tall, it's no lightweight heatsink and fan assembly. All this helps to set it apart in a competitive market.

With that in mind, let's examine how the AK620 Digital adds performance and its place in the aftermarket cooling landscape.

Packaging and bundles

The DeepCool AK620 Digital CPU Cooler is presented in sleek packaging, with a simple cardboard box adorned with a stylish ribbon for an added touch of elegance. The cooler is securely packaged for transit, placed in a nylon bag and cushioned with a foam insert to ensure it arrives in pristine condition. On the back of the box, the key features and performance highlights of the AK620 Digital are prominently displayed, giving potential buyers a brief overview of what this cooler brings to their PC setup.

Opening the packaging reveals a small cardboard box containing the necessary mounting accessories along with basic, straightforward instructions. All you need to install the cooler is a syringe of premium thermal compound and a very basic screwdriver. The included mounting kit is compatible with a wide array of CPU sockets, making the AK620 Digital versatile for use with a variety of Intel (1700/1200/115x/2066/2011) and AMD (AM5/AM4) processors.

Deep Cool AK620 Digital CPU Cooler

The Deep Cool AK620 Digital CPU Cooler stands out in its category with a robust dual-tower design, featuring six premium 6mm copper heat pipes that transfer thermal energy from the base to dual large fin arrays. The designer made the cooler completely black, spraying every metal part with matte black paint and using two all-black fans. This cooler reaches a height of 162 mm, so compatibility is a consideration for many cases. At around 1.5kg, the AK620 is one of the coolest coolers on the digital market, highlighting the importance of removing the cooler from the motherboard during system replacement to prevent any potential damage.

Deep Cool's engineers have designed the fin arrays to be quite dense. The front intake and rear exhaust form a checkerboard pattern, possibly as a measure to reduce aerodynamic noise, yet the fins facing the center fan are perfectly straight. The front row has an additional notch for running digital display cables, which slightly improves cable management. We also found a top fan scratch from some kind of tool, probably during the manufacturing process, but it's under the top cover so factory quality control probably missed it.

The base of the Deep Cool AK620 Digital is a basic metal block that braces the heatpipes and contact plate, while also serving as a support for the mounting brace. Both the top and the mounting brackets are sprayed with 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, as is the case on any high-quality cooler today – however, Deep Cool took it a step further and plated the copper as well, giving a The perfect mirror will oxidize over time.

One of the most prominent features of the AK620 Digital is its very high quality fans. DeepCool is using two FK120 (DF1202512CM) fans with a Fluid Dynamic Bearing (FDB) engine and custom frames with shock absorbing material. The fan has a maximum rotation speed of 1850 RPM and is a high airflow/low pressure design with many small blades. This type of fan is generally used when the expected airflow resistance is minimal. The fans lock onto the fin arrays with standard wire braces, which also allow for adjustable front fan mounting height to clear RAM modules if and when necessary. Also, if you need to move the fan, keep in mind that increasing the height of the fan will both require a case with more clearance, and there may be a small loss of performance. .

The main feature of the AK620 is its digital display at the top, which works through the JUSB motherboard header. Additionally, DeepCool has installed A-RGB LED strips on the edge of the top cover for that extra flair. Digital display operation is separate from RGB lighting, which is connected to an A-RGB controller header, on the motherboard or third party. This requires the installation of a basic software driver, which offers very limited programming options, such as switching the temperature unit 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 function of the cooler in any way. The display has only one orientation, so the cooler needs to be installed in a specific orientation.
