Bequiet Silent Wing strange noise without dust filter

[deadrobotxd]

Hello, i recently bought a silent wing 3 to my case but it makes a vibrating sound when is the filter off, it doesnt really affect when the filter is off but i wonder if something is wrong with the fan or if it is just the case or mounting

There is the clip of how it sounds

Oh wow that sounds nuts indeed. Good showing it in the video. Did you try to attach it with the screws? It sounds normal if not attached to the case?

 

Look like its running at pretty high RPM also, maybe tone that down a bit.

Sounds like the fan isn't mounted far enough away from the case and is creating a lot of turbulence.

You could try some rubber fan spacers to see if that creates enough of a space between the case and the fan, something like this:

I had the same issue with my O11 Dynamic case where the bottom fans are mounting flush up against the case, this created a horrible noise with the fans i was using at the time, my solution was to cut a nice big rectangle out of the bottom of the case, this way the only thing impeding the airflow was the fan filter, added some spacers to get the fans a little further away from the filter and now they are basically silent.

Yep sounds normal when is not attached and same issue with screws, must be turbulence like the other guy said, and dont worry the rpm was just to show the sound more clearly  haha

Nice, gonna try getting those and hopefully it helps if not then i will go DIY too.
