Methodology
A Ryzen 5 3600 has to be cooled at factory settings, joined by 16GB Crucial Ballistix Sport (2x8GB) DDR4 memory on an MSI B550 Tomahawk (BIOS 7C91vA9). The Asus ROG Strix GTX 1060 6GB runs in zero-fan mode for the CPU stress tests only and a Fractal Design Ion Gold 750W serves as the power source. The whole thing is housed in the Thermaltake Core P3 as an open benchtable.
All records are logged with HWInfo64 v6.30-4240 – 2000ms logging, the specified temperature is derived from the sensor CPU Die (Average). The load of Prime95 produces an average of 88 watts of CPU package power. Since I don’t have air conditioning, the values in the graphs are the delta between room temperature and CPU temperature. This allows all cooling systems to be compared fairly, even if the ambient temperature is different. The thermal paste included with the cooler or pre-applied is used in each case.
I determine the sound level with a Voltcraft SL-200 meter at a distance of 40cm, which operates in 125ms cycles in Lo mode. The room was measured at 33.2 dB(A), an external sample table helps to break it down.
Benchmarks
I have saved myself new tests with only one fan, you can simply read the article from the normal AK400.
2 fans |
30% PWM |
60% PWM |
100% PWM |
Speed fan front |
555 RPM |
1054 RPM |
1596 RPM |
Speed fan back |
552 RPM |
1057 RPM |
1602 RPM |
Sound level / characteristic |
33.3 dB(A) |
34.4 dB(A) |
40.7 dB(A) |
Ambient temperature |
22,4 – 22,6°C |
22,8 – 23,0°C |
22,9 – 23,4°C |
And that’s how this cooler compares to competitor offerings of about the same price:
Summary and conclusion
And with that, the last cooler on this processor has completed its test run. Cleanly manufactured and blackened, no points of criticism can be found in the workmanship. Installation is a bit fiddly, but the bracket spacers hold onto the screws by themselves. So you can do the whole thing quite well on your own.
Only when evaluating the results did I notice that the Zero Dark variant has other fans with 200 RPM lower maximum speed according to the data sheet. I have assumed that these are identical to the normal AK400. The R-AK400-BKNNMN-G-1 (AK400) and R-AK400-BKNNMD-G-1 (here) are slightly different, but both are pleasantly quiet in operation.
Depending on the processor, you may prefer to install the second fan in the case; it is usually of little use on these compact coolers. In terms of cooling performance, this cooler lands in the midfield, but is nice and quiet at the same time. If you like the looks, you will get a chic air cooler in either almost completely black or white for a good price.
The test sample was provided by Deepcool without obligation. There was and is no influence on the tests and results. There was also no compensation for expenses and no obligation to publish.
