Design and Aesthetics of the AK620

When looking at the DeepCool AK620 CPU cooler, one of the first things that caught my eye was its minimalist design. There’s a prevailing trend among PC build enthusiasts to opt for flashy RGB lighting, but the AK620 steers clear of this, prioritizing a more subdued appearance that can blend in with any build. That said, the lack of RGB might be a downside for some, but I appreciate the sleekness it brings to my setup.

Here’s a quick rundown of what sets the aesthetic of the AK620 apart:

  • Dual-tower “Chessboard” fin design: Not only does it look modern and unique, but it also serves a purpose, optimizing airflow for better cooling efficiency.

  • Top decorative boards on the heatsinks: These add a nice touch of class, distinguishing the cooler from more utilitarian-looking competitors.

  • Minimal branding: DeepCool keeps it classy with just a subtle logo on the top, avoiding the brand-heavy look of some other coolers.

In terms of build quality, the off-black, almost gunmetal color of the aluminum fins and heat pipes give it a premium feel. The craftsmanship is apparent—there are no sharp edges or cheap plastic parts to be found here.

However, the larger size of the unit was something that initially caused concern. It stands quite tall at 160mm and is definitely bulkier than a stock cooler. While this didn’t pose a problem for my case, which could accommodate its size comfortably, I can see it being an issue for those with more compact cases or who prefer a more low-profile setup. So, double-check your case clearance before taking the plunge.

The 43mm clearance for standard RAM was sufficient for my build, but I can imagine the need to adjust fan heights for those using RAM sticks with taller heat spreaders. Thankfully, the cut-out fin design gives you that extra flexibility if necessary.

On the flip side, there are some undeniable advantages:

  • Silent performance that doesn’t compromise on efficiency.

  • A design that supports heat dissipation for even overclocked CPUs, thanks to its ample TDP of 260W.

While the aesthetic of a CPU cooler is not everyone’s top priority, there’s no denying that the AK620’s design is thoughtful—not just in terms of looks but also functionality. The no-frills, utilitarian approach DeepCool has taken with the AK620 is refreshing, offering builders an option that’s both understated and effective. Sure, it might not be the right fit for everyone’s taste or case constraints, but for those who appreciate clean lines and quiet operation, it’s right on the money.

Installation Process and Compatibility

When I decided to upgrade my CPU cooler, the DeepCool AK620 caught my attention due to its mix of performance and aesthetics. Before jumping into the installation process, I had to make sure it was compatible with my system. It boasted wide compatibility with both Intel and AMD sockets, including the latest AMD AM5 and Intel 1700 platforms. This gave me peace of mind, knowing it could handle future upgrades.

Here’s a rundown of my experience with the setup:

  • Read the manual: The included instructions are clear with separate sections for Intel and AMD installations.

  • Check your case size: The AK620 stands 160mm tall, so make sure your case can accommodate this height.

  • RAM clearance: With 43mm standard clearance, it’s versatile, but be sure to adjust the fan height if you’ve got those sweet-looking high-profile RAM sticks.

  • All-metal bracket: It feels sturdy, and having an included screwdriver was a nice touch that simplified the process.

I won’t lie, the installation was a bit intimidating at first. This cooler is sizeable but the fear was unnecessary. The all-metal mounting bracket provided a secure fit once everything was lined up. However, it wasn’t without its quirks. The provided magnetic screwdriver just barely met the required length, making it somewhat tricky to navigate around the tall heat sinks. Plus, applying the right amount of pressure when fastening the screws was a balancing act between securing the cooler and not damaging the motherboard.

As for compatibility, the adjustable fan height was a godsend. High-profile memory modules are a staple in many builds, and the AK620 accounted for that. The cut-out fin design meant no headaches with RAM slots, which is more than I can say for other coolers I’ve wrestled with in the past.

Here’s a markdown list summarizing my key takeaways from the installation:


  • Informative, hardware-specific manual

  • Provided screwdriver (although could be longer)

  • Ample RAM clearance with adjustable fan height

  • Broad compatibility across CPU platforms


  • Magnetic screwdriver length

  • Installation pressure can be nerve-wracking

In the realm of PC building, user experience and product adaptability are critical. While the AK620 installation posed a mild challenge, mostly from exerting enough force without causing damage, the process was a valuable exercise in patience and precision. The payoff, however, was instantly gratifying when I saw my CPU temps drop while maintaining a near-silent operation. Despite the minor stumbling blocks, I was ultimately happy — another testament to the reality that great things in the PC world don’t always come easy. This puts the DeepCool AK620 on the list of coolers I’d recommend, but with the caveat to prepare for a little elbow grease during installation.

Cooling Performance and Noise Levels

When it comes to keeping my CPU cool under load, the DeepCool AK620 has been an impressive performer. Here’s a rundown of my thoughts on its cooling performance and noise levels:

  • Efficient Heat Dissipation: With a TDP rating of 260w, I’ve found the cooler adept at handling the heat from my overclocked CPU. It has managed to keep things considerably cooler than my previous cooler, which I definitely appreciate during intense gaming sessions.

  • Noise Levels: While noise is subjective, I’d say the cooler operates quietly under normal usage. Sure, there’s a bit of noise when the CPU is under full load, but it’s not overwhelming. It’s a noticeable hum that doesn’t intrude on my concentration or gaming audio.

  • Speedy Fans: The high rotational speed of the fans at 1850 RPM means more efficient cooling but can also mean a little more noise as they really get going. Even then, it’s more of a white noise rather than a distracting sound.

Coming from a liquid cooling setup, I was initially concerned about the noise levels of an air cooler. However, the AK620’s dual FK120 fans have a maximum noise level of 28 dB(A) according to the specs, which, based on my experience, seems fairly accurate. Only during peak loads did I notice the fan noise, but even then, it wasn’t disruptive. The included low noise adapter is a thoughtful addition for users particularly sensitive to fan noise.

Another aspect to consider is the presence of noise damping pads in the fan corners, which works effectively to minimize vibrations — a common contributor to annoying sounds. This is an example of attention to detail I appreciate.

However, it’s not all sunshines and rainbows. There are some caveats to note:

  • On the noise front, it’s essential to tailor your fan curves carefully. Certain RPMs can lead to a resonant hum that can be irksome if you hit the wrong frequency. It’s something that can usually be managed via your motherboard’s software but is worth mentioning.

  • The cooling proficiency, while fantastic for my needs, might not stack up against a more robust AIO if you’re pushing your CPU to its absolute limits. That said, for most users, including myself, this cooler provides more than adequate cooling performance, even with a bit of overclocking thrown into the mix.

In the territory of air cooling, the AK620 certainly holds its own, blending quiet operation with serious thermal management abilities. It’s quiet enough to not be a distraction during everyday tasks and yet powerful enough to ramp up when the CPU starts sweating. The silent efficiency this cooler promises isn’t just marketing fluff—it’s genuinely delivered in my use case.

Value for Money and Overall Impressions

When assessing value for money and overall impressions of the DeepCool AK620 CPU Cooler, I’ve got to consider a few crucial points:

  • Price: It’s relatively cheap compared to some heavyweight names in the market.

  • Performance: It keeps up with its promises, maintaining cool temperatures even during intense sessions.

  • Noise Levels: While not silent, it’s quieter than many competitors, especially under load.

  • Installation: It’s manageable, though not the easiest I’ve ever done.

  • Extras: The inclusion of a screwdriver and thermal paste is a nice touch.

For the budget-conscious builder, the DeepCool AK620 strikes an appealing balance between cost and performance. Despite not being the lowest-priced cooler on the market, it definitely punches above its weight class, performing on par with much more expensive units like the infamous Noctua series. That alone makes it a compelling choice for anyone looking to get the most out of their buck.

I appreciate the thoughtful extras like the screwdriver and thermal paste — it’s a small thing, but they show DeepCool’s commitment to ensuring a complete package. However, those who are new to installing coolers might find the mounting pressure required a bit off-putting; it’s nerve-wracking to apply that much force when you’re so close to your motherboard.

Now, noise is subjective, and while the AK620 is not the quietest air cooler I’ve encountered, it’s still impressively silent most of the time – unless you push it into overdrive. If you’re interested in alternative cooling solutions that prioritize low noise levels, you might find the Noctua NH-L9i Low-Profile CPU Cooler to be a suitable option. If your case has sound dampening, it’s unlikely this cooler will disturb you in the slightest.

Drawbacks? They exist, but they’re not deal-breakers. The cooler’s size could pose a problem in smaller cases, or if you’re using RAM with tall heat spreaders. And the mounting system, while sturdy and secure once in place, could be more intuitive for the less experienced builders.

Looking at the overall picture, the DeepCool AK620 has been a satisfactory workhorse in my rig. It’s maintained cool temperatures, didn’t break the bank, and the subtle design doesn’t scream for attention inside the case. For many users, those benefits are exactly what’s needed. While it’s no unicorn in the world of CPU coolers, it’s definitely a solid thoroughbred that deserves consideration for your next build or upgrade.
