Question Rattling case fan

[Stargazer86]

The front fan in my computer seems to have developed a bit of a noise. When I start things up it'll emit a loud buzzing sound. The only "solution" I've found is to open up the front and press down ever so slightly on the middle of the fan, this moves it inwards a millimeter or so and stops the buzzing. However, once I shut down for the night the buzzing will return when I start it up again in the morning. Then I have to open up the front, press down on the middle of the fan again, and it'll stop for the rest of the day.

I've already cleaned it, so I don't think dust is making it unbalanced, and I've also removed it and then reset it back into place in case it had become loose and was wobbling. This seems to have helped a bit but hasn't entirely solved the issue. Any ideas?

Replace?
Have you checked beyond the sticker on back of it (you need to peel it of) that the securit plastic ring/metal ring havent fell off, which would be very rare

It seems like it's just shifting ever so slightly. The fan itself looks a little loose and just ever so slightly wobbly. I don't know why messing with it for a bit solves the problem for a day but then it starts up again the next morning. I guess I should just replace it?

Replace it, bearing is probably gone.
