The fan was very well packed and met my extensions. The accessory was very comprehensive. 4 simple screws "rubber brackets", a better term is not a need to get, and a low noise adapter were in the box. I can about the "rubber clamps not say much because I do not use these. Appear to be for the decoupling. The low noise adapter is excellent. Just plug and the fan only runs at 100% with 800 U / min.
In the horizontal position of the fan generates a slight indeed, but quite noticeable, humming noise. I do not know if it only one batch is concerned, or whether general bad components are present. I personally do not mind, because it's not really pushy. Wanted to mention it only because here in the recessions anyone ever mentioned the problem and it is thus not a
Individual case is.
Update
After 2 months, the hum developed into a grinding and also the change in the rubber mounts brought no improvement. I can see the fans now clearly no longer a friend for horizontal use. However, in the vertical they perform their duties as before.
