The editing was laborious, you really be patient with these flexible mountings, they are too flexible to fit in the holes of the fan.
It should be known as a brute force that it fits ...
-1 For these fasteners.
Then the fan is not inaudible, without adapter, it made more noise than the Intel processor fan 2500k to 1200 rev / min, but breakdown was.
With low noise adapter provides, it is almost inaudible: we hear more against the intel fan but allocates as much as a shadow ... be quiet for as much noise.
So I did not find useful to try the ultra low noise adapter provides.
Finally, a good fan, with a full bundle, which can adapt to the desires and changes of a user.
