Also I wanted to decouple my fan from the case and have decided for this. The installation of the rubber plug is very easy, simply place the screw through the screw holes Pull the fan and the housing. The fans are thus decoupled from the housing and wonderful one notices it that it has become a little quieter now and the vibration has subsided. The quality is not bad either, the small rubber plug can neatly pull without this tear. The advantage is also that are to change the fan speed or can be mounted differently as with screws. I will always use the decoupling from now.
Change 09:01:15: I had to edit my review today, since the plugs were very soft and sticky, thus the fan no longer held and the stopper slipped out again. It looks as if the plugs dissolve. It probably involves a material error. Have now tried a different brand, let's see how they are.
