With 1 fan that I have installed, it keeps the processor cool at around 36° in idle and 40-70° in demanding games and stress tests without noise. A very good choice and the white LED does not clash with the case.

Good, quiet, as effective as I expected, but I'm still waiting for the thermal paste to "settle" which will take another month.

Ryzen 3600x slightly overclocked Idle 32-35 degrees, in stress test maximum 64.
With the stock, it was Idle 47-50, and in stress test 81.
It is worth its money since the much more expensive and famous ones do not offer
higher performance compared to their price difference.
The build quality is amazing, it has nothing to envy from any other more expensive liquid cooling and even provides a container with liquid to refill in case its performance starts to decrease over time.
Also, it is really silent, and that is the main reason Be Quiet was chosen. You have to get close to the case to hear anything.
Finally, I have never seen another AIO liquid cooling with its pump in its tubes, and this is to prevent vibrations in the socket from its operation and to avoid extra noise.
Finally, in terms of appearance, it has a white LED around the water block which beautifies it a lot without making it look too flashy and makes it match any RGB or non-RGB composition, and above all, without losing its "seriousness".

P.S. It was tested and continues to operate with Thermal Grizzly Kryonaut paste.
P.S.2: For some inexplicable reason, monitoring with HW Monitor is not recommended.
Prefer Ryzen Master.

First time with an AIO. I wanted to combine my case, Be Quiet Pure Base 500 Window, with the fans it has, with an AIO from the same company. Initially, I cooled a Ryzen 5 3600. With the stock cooler, I had temperatures of 50-60 degrees Celsius at idle and 85-89 degrees Celsius while gaming. I had changed the thermal paste, but there was no improvement. I decided to try my luck with an AIO. With the AIO, I had temperatures of 34-40 degrees Celsius at idle and the processor didn't exceed 51 degrees Celsius during a stress test for half an hour. We're talking about a crazy temperature difference.

I installed the AIO at the front with the tubes on top. Its installation was incredibly easy. The build quality is excellent. Plus, it includes 100ml of cooling liquid for refilling the cooler. I also used the thermal paste included in the package. As for the noise, I couldn't hear anything significant. It was within normal limits in a quiet room. The system could be heard when you got close and listened carefully.

I don't know if I should add anything extra. Since I saw almost a 40-degree decrease in the processor's temperature, it's obviously an excellent choice for me.

The white LED on the cooler looks beautiful in a simple, monochromatic build. It's not RGB. That's all. 10!

UPDATE: 26/4/2021. The AIO continues to perform well. The PC is on, specifically from 11 in the morning until 2 in the evening. Sometimes browsing, sometimes gaming. Warzone, Cold War for 6 hours straight. And the processor stays at 54-57 degrees Celsius. It doesn't back down, guys! If you really want RGB, go for the new AIO released by the company. Personally, the Pure Loop is much more beautiful than the new one. If there's any difference between the two, it's the fans. Pure Wings 2 are beautiful and capable fans, and the Silent Wings 3 High Speed in the new AIO are even better than the two. If you don't like the aesthetics of the new one, go for the Pure Loop and spend some extra money on the Silent Wings 3. For me, Pure Loop AIO is a fearless choice!
