DeepCool AK620

Testing

The following system was used to test the cooler:
– Processor: Intel i9 9900K @ 5GHz
– Motherboard: ASRock Z390 Phantom Gaming X
– RAM: Neo Forza Faye DDR4 64GB 3600MHz
– GPU: MSI GeForce RTX 2070 Super Gaming X Trio
– SSD: Crucial p5 500GB
– HDD: GOODRAM IRDM 1TB SSD
– PSU: Seasonic Snow Silent 750W Platinum
– Case: be quiet! Silent Base 802 White
– Thermal compound: Noctua NT-H2

 

Software used for testing the cooler:

– AIDA64 Extreme Version: 6.60.5900
– Intel Burn Test v2.54
– Prime95 29.1

The cooler was tested with the CPU at the default turbo frequency of 4.9 GHz and overclocked to 5 GHz with a core voltage of 1.261 V.
Also, the included fans have been used at their maximum speed.
The room temperature was approximately 26°C (78°F), with 2°C margin of error.
The idle test consists of the CPU sitting idle at the desktop for 30 minutes, the temperature was measured at the end of the test.

 

The settings of the software used are the following:
Intel Burn Test v2.54 – Stress level: Maximum
Prime95 29.1- small FFT
AIDA64 Extreme Version – FPU Benchmark & Temperature monitoring.
Each test was conducted for 40 minutes.

 

Idle

 

Full Load – IntelBurnTest V2

 

Full Load – AIDA64 CPU, FPU & Cache

 

The noise level was measured at three different distances from the fans (10cm, 20cm, 30cm.) the noise was measured with a margin of error of ± 2 db.

 

The DeepCool AK620 has an average RAM clearance, with approximately 40mm of space below the front fan. In addition, the front fan of the cooler covers all four RAM slots of the motherboard.
With regular RAM modules, the CPU cooler will work, however, tall RAM modules will require the front fan to be moved up.

 

The PCIe clearance with the DeepCool AK620 installed is average, with approximately 27mm of space between the CPU cooler and the graphics card. This space is enough to access the top M.2 Socket of the motherboard but not ideal, especially with large graphics cards.

 

Final thoughts

The DeepCool AK620 is a good CPU cooler, that not only looks great but it is very well made. The design of this CPU cooler is on the same level as what we see from Noctua or be quiet! This is thanks to not only the usage of high-quality materials but the complete lack of RGB LEDs and “gaming” inspired plastic components.

The AK620 uses two 120mm fans that will do their job but also create a higher-than-average noise output. These fans also do not have any type of sleeving on the wires and they use a standard Fluid Dynamic Bearing system.

The cooling performance of the DeepCool AK620 is good, and around the same level as the be quiet! Dark Rock Pro 4 or the Noctua NH-U12A. However, while the cooling performance is good the before mentioned noise output is not. There are many CPU coolers that use 120mm fans that are quieter and perform just as good or better.

The installation is easy, thanks to a simple mounting system and all metal components. However, the lack of a physical user manual is unacceptable even though a lot of manufacturers are doing the same. Relying on the end user to always have an internet connection on their smartphones or other devices in order to not print a user manual is not a good decision.

While the DeepCool AK620 is a good CPU cooler, it has its shortcomings. Starting with the average at best clearance for both the RAM and graphics card. The biggest drawback of this CPU cooler is the noise output which is higher than what you’d expect.

In conclusion, the DeepCool AK620 is a good air CPU cooler that is not only well made but looks great as well. The cooling performance is good and around the same level as the high-end air CPU coolers. The only drawbacks of the AK620 are the average clearance and the higher-than-average noise output.
