Test setup and results …
For the practical test, we have installed the Asus ROG Ryuo 240 water cooling system 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
Cooler Master Testbench v1.0
For measurement, the following tools were used: Prime95 and SpeedFan.
The ambient temperature during the test was about 21°C.
The Asus ROG Ryujin 360 first competes against the AMD Boxed cooler as usual. If you want, you can also join our recently released test of the Asus Ryuo 240 AIO water cooling, which was tested under the same conditions, and compare the results.
Another special feature of the Asus ROG Ryujin 360 is that on Asus motherboards you could connect the fans to the cooler via the two 4-pin PWM sockets and connect the cooler with the 4-pin PWM connector to a 4-pin CPU cooler connector on the motherboard. You could then use the Asus own software AI Suite 3. However, since our test system is equipped with an ASRock motherboard, at least this way is denied.
Instead, we connected and regulated the fans separately via a 4-pin PWM Y cable and the CPU cooler to a 4-pin PWM fan connector. Here, the pump integrated in the cooler always ran in the same control mode as the fans, with 40% being the minimum for the pump, i. at 20% fan speed, the pump ran at 40%, at 40% fan speed, the pump ran at 40%, and so on …
As the AMD Boxed cooler is not really a serious opponent for a 360 AIO watercooling, we also – as in the case of the Asus Ryuo 240 review – sent the Noctua NH-D15 into the race as opponent.
We then used the CPU for 30 minutes with Prime95 and recorded the temperatures.
Of course, the Asus ROG Ryujin 360 water cooling beats the AMD Boxed cooler both in terms of temperature and noise level. For the first time, the Noctua cooler can be beaten, at least in terms of temperature. The Ryujin 360 undercuts it at the temperature values, but paid for it with a slightly higher noise levels.
Here is the same picture, as on the AMD A8 APU: Although the NH-D15 has been beaten in the temperatures, the Ryujin 360 paid for it with a higher volume.
The cooling performance drops only moderately even at 40% pump speed, so that you can calmly control the pump in favor of a quieter operation.
The fan volume is measured with a dB meter from 100cm distance. In addition, we determine the respective rotational speed. In the case of the Asus ROG Ryujin 360 watercooling, however, the pump was also included, so that the values remain practical.

The fans can score with a very good control range, which allows both the silent operation and full throttle. The fan noise is free of noise.
To be able to estimate the fans better, we have a video as usual, by letting the speed range run completely up and down again.
It is not uncommon for AIO water coolers to encounter a slight pump hum or buzzing, which unfortunately we have also noticed in the Asus ROG Ryujin 360. However, since the pump can be regulated so well by PWM, you can also fine-tune this. Again, we have a short video.
Overall, however, the whirring is so low that it quickly goes down in the fan noise as soon as you switch them on.
Let us now turn to the optical criteria of AIO water cooling.
