My HOB filter constantly makes an RRRRR sound that can be heard from a whole floor above any ideas for quieting?

It most likely the impeller making the noise. You might be able to quiet it down with some silicone grease applied to the magnet of the impeller. I personally used Vaseline with no ill effects, but apparently its bad for the fish or something like that.No lid, not sure, I don’t have the warranty just the filter
