Methodology
An AMD Ryzen 9 3950X has to be cooled in various power consumption levels, plus 16GB Crucial Ballistix Sport (2x8GB) DDR4 RAM on an MSI B550 Tomahawk (BIOS 7C91vAB). The Asus ROG Strix GTX 1060 6GB runs for the CPU stress tests only for the image output in zero-fan mode and a Fractal Design Ion Gold 750W serves as the power source. The whole thing is located in the Thermaltake Core P3 as an open benchtable.
The test system runs on Windows 10 Pro 22H2 (Build 19045.2251). All data sets are recorded with HWInfo64 v7.34-4930 – 5000ms logging, the specified temperature results from the CPU Die (Average) sensor. Since I don’t have air conditioning, the values in the graphs are the delta between room temperature and CPU temperature. This means that all cooling systems can be compared fairly, even if the ambient temperature is different. The heat-conducting paste supplied with the cooler or applied beforehand is used in each case.
I determine the sound level with a Voltcraft SL-200 measuring device at a distance of 40 cm, which works in 125 ms cycles in Lo mode. The room was measured at 33.2 dB(A), an external example table helps to break it down.
Benchmarks
In the first test run, a loudness of 40 dB(A) was set at a distance of 40cm from the center of the front, in my setup this is 78% PWM with both fans installed:
And after that, this cooler is still allowed to show what it can achieve in terms of cooling performance at maximum speed, regardless of the volume. A maximum of 47.0 dB(A) was achieved at 100% PWM and a distance of 40 cm.

Summary and conclusion
I think the linked comparison shows it quite well, at the time of testing the AK620 can play at the top and almost outperforms the Assassin IV.
However, with an installation height of 160mm, this air cooler doesn’t fit into every midi case, so you should definitely keep that in mind. However, this also applies to the other front runners, a lot of cooling capacity comes at the price of a large heat sink.
As always, looks are a matter of taste, but purely in terms of performance, the AK620 makes a really good impression for the current price of 65 euros and is practically on a par with the more expensive flagship from the manufacturer’s own range. If you are looking for a good all-round air cooler and have enough space in the case, this is a tempting offer.
