[SOLVED] Wobbling/loose fan blades

In the video you can see the front fan wobble and kind of loose (I can push it up with my finger, and it falls down when I let go of it). It makes horrible noise when running.

Looking at some videos on "removing fan blade" I guessed that something is wrong with the restriction ring but I'm hesitate to remove the fan blade.

Anyone experienced something like this before? Any wild guess on what could be causing the problem ?
I'm using Metalicgear Skiron 140mm fan

Bearing failure, or it has fallen out. Probably both.

Replace the fan, if under warranty, they should send you a new one.

I ended up taking the blades out, and put it back in again. Everything works fine now and I have no idea why

Just a little loose on the press fit I imagine. They can't all be perfect.

Maybe swap that one for a horizontally mounted fan so that it doesn't fall out again.
