So close to perfection!
I have to say first of all that when I choose a cooling system, the noise level is the parameter I look at with as much interest as the cooling performance.
So after a lot of research I found this Arctic Liquid Freezer II which seems to meet all my expectations both on performance and noise. The tests are unanimous and for a very competitive price!
I chose the 360mm since it's an I7 10700k to be cooled.
The installation is very simple, but be careful to have a case that can accommodate it (on a Fractal define it passes without problem). The tutorial is well done even if we would have liked a paper version (but I'm quibbling).
From a performance point of view, it's all good after testing via 3D Mark and Cinebench, the arctic does very well.
But from a noise point of view... So : The pump and the fans are very quiet, no problem, I was even very surprised!
But the worry on my side comes from the small fan intended to cool the VRM. However, the tests described it as inaudible but it was not the case for me.
Maybe I am too sensitive to high pitched noises but I was constantly bothered by the acceleration and deceleration of the fan producing the slight high pitched noises. Be careful, it is still contained but for me it is unbearable.
Too bad then, I send it back and come back with my good old Noctua u12a
