That is presumably the broken fan, if it was the left side one, when in proper position.
Three screws, one connector and some (atleast in this picture I got from Reddit of the same model) QR code that might tell you which part that is.
Before you give up, might as well figure out what the QR code is, if it doesn't tell you what it is or you can't find online the separate part, then might as well give up.
No sense in buying the whole kit, when just one part is broken.
If it's the other fan, that looks trickier to change. that one black wire just running over one of the screw spots... Who the fuck designed that?
