PS5 fan has a strange stain?

So when I opened it I didn't see the stain from me

Caused by the noise

That is firmly the stain.

It looks like a piece of a snackini

I have no idea wqr just d

It's hard to go away

Did they eat pizza while assembling? 🤣🤣🤣

That could be sealing varnish.

But that doesn't cause the noise or because I don't want to take it away it's too firm

If it is a little stronger, it can be a small weight to counter imbalance, similar to car tires.
