advantages but also some shortcomings
Watercooling quite efficient. Placed externally at the back of the case, my Ryzen 5 3600 goes up to 77° maximum with all cores running at full speed for 45 minutes (compiling and encoding large 4K video files). Radiator with very good dissipation. There could be more performance but this is a small heatsink model so it's not bad.
I like the closed circuit assembly without the need to add liquid. But on the other hand, the blocks are not removable.
The socket fan is a good idea.
It comes with just the right amount of thermal paste.
The pipes are very rigid. So anticipate if mounted inside the case.
Radiator fan: when mounted externally, it is not quiet, even at idle regulated by the motherboard. This is really THE big flaw.
It is not at all bright: probably an error in the LDLC description.
Conclusion: good value for money.
