Suited me 1

- Fully meets speed changes,
- At 760tpm it is virtually inaudible.
- Comes with, in addition to conventional screws, kinds of rubber rods that can replace and which absorb vibrations that the case then would charge to amplify. But I confess not know whether it really brings something.
- Sleek, although this point is purely secondary (my ventilos are hidden in the case, even though it has a transparent wall.

Against:

- In "normal" speed, ie 1200tpm, it is NOT quiet, far from it.

=> Remember to indicate in the bios that supports variable fan speeds, or it will turn permanently 1200tpm; and there, indeed, it is very far from silent.
