Test setup and results …
For the practical test, we have installed the Scythe Ninja 5 on our new AM4 test system, which consists of the following components:
ASRock Fatal1ty AB350 Gaming K4
AMD A8-9600 @ 3.8 GHz with 1.4 Volt
4GB DDR4-2400
Cooler Master Testbench v1.0
For measurement, the following tools were used: Prime95 and SpeedFan.
Thermal compound: Scythe (included)
The ambient temperature during the test was about 21°C.
The Scythe Ninja 5 as always, competes against the AMD Boxed cooler, but you may also want to check out our recently released test of the Cooler Master MA610P and the Cooler Master MA620P which were tested under the same conditions and compare the results.
We then used the CPU for 30 minutes with Prime95 and recorded the temperatures.
Of course, the Scythe Ninja 5 beats the AMD Boxed cooler in both temperature and noise levels.
In addition, to put the Ninja 5 in front of a just challenge, we have it also compete against the Noctua NH-D15. But this time on an AMD Ryzen 7 1800X.
Here, the Ninja 5 has indeed been beaten at the temperature, but if you look at the values in terms of volume, both opponents are almost equal, that means at the same volume and temperatures are both cooler almost equal. A great result for the Ninja 5.
The fan volume is measured with a dB meter from 100cm distance. In addition, we determine the respective rotational speed.
| Scythe Ninja 5 | ||
| 20% | 32dB | 465rpm |
| 40% | 33dB | 543rpm |
| 60% | 33.5dB | 630rpm |
| 80% | 34dB | 716rpm |
| 100% | 35dB | 759rpm |
Here you can see once again that Scythe has tuned the fans very quietly. Even at 100% they are barely audible. A dream for any silent lover. The fan noise is free of disorders.
To be able to estimate the fan noise, there is again a video with the full rpm range:
