DeepCool AK620 Digital CPU Cooler Review

Two years ago, Mike reviewed the DeepCool AK620 Air Cooler, it was pretty great, but there’s always room for a little improvement. Now DeepCool is back with a new version, the AK620 Digital, with a new all-black design, improved fans, a new top cover that has a built-in LCD display, and a touch of RGB for good measure. It’s basically the same core cooler design though, but I’m hoping to see some general improvements in performance as a result, not just aesthetic improvements.

The features list looks good though, with the new Digital version coming with that real-time temperature and CPU utilisation readout right on the top, not needed, but hey, it’s still pretty cool. The cooler itself features 6 x 6mm heat pipes through a large copper coldplate, with the heat pipes and cooler finished in an all-black design, while the older one was an all-silver finish.


  • As the first member of DeepCool digital CPU air cooler, the newborn AK620 DIGITAL carries everything you love about the classical AK ZERO DARK Series, with the sleek low-profile magnetic status display and ARGB LED strips.
  • DeepCool AK620 DIGITAL features six pieces 6mm all-black heatpipes with raised copper coldplate to maximize heat dissipation to overall 260w TDP which supports even overclocked CPUs for mighty gaming performance. AK620 DIGITAL carries a thermal paste in package, please apply it on after removing the protective film of coldplate.
  • Heatsinks of AK620 DIGITAL CPU air cooler is covered by a digital screen to display the real-time temperature and utilization of system’s CPU, number on screen will flash as warning when CPU temp is over 90℃(194℉). The display requires an open USB 2.0 header for data synchronization and is controlled via a simple application which can be downloaded in DeepCool official website.
  • Tired of crazy bling CPU coolers but don’t want the zero-light style? DeepCool AK620 DIGITAL offers a solution in balance. Two slim ARGB LED strips are attached on the digital screen sides, whiches combine the minimalism of AK ZERO DARK with proper cyber style as the new design language of DeepCool aesthetics.
  • High-speed FK120 120mm FDB fan on AK620 DIGITAL CPU air cooler features 1850RPM and 68.99CFM airflow to build an efficient air cooling system, noise damping pads in fan corners avoid vibration whiches keep noise level under 28dB(A) even in full load, meanwhile, a low noise adaptor is contained in the box for quieter using experience.
  • AK620 DIGITAL CPU air cooler measures 138mm width without blocking most RAM, the fan can be adjusted to proper height if RAM slots are too high to be compatible with; Standing 162mm height is compatible with most ATX/ M-ATX case, checking CPU cooler height limit of PC case before buying is highly recommended.
  • AK620 DIGITAL CPU Air Cooler widely supports Intel LGA 1700/1200/1151/1150/1155/2066/2011-v3/2011/AM5/AM4 with suitable bracket in the box. Please leave the protective film over the display in place until the installation of your new cooler i s complete; this will ensure that the glassy panel stays as pristine as possible.

As a child still in my 30's (but not for long), I spend my day combining my love of music and movies with a life-long passion for gaming, from arcade classics and retro consoles to the latest high-end PC and console games. So it's no wonder I write about tech and test the latest hardware while I enjoy my hobbies!
