Maybe its finally time to change out fans...

Testament to how much better the aluminum case fans are: These have both had broken blades and been off-balance for almost 6 months. They make a terrible humming noise when running, but they still spin smooth! Those are some solid bearings.

The only reason I'm retiring them is because the last few fan blades on the left one finally broke off. It doesn't really blow air without fan blades

The one on the right still blows decent air though! So maybe I'll just be cheap and replace only the left one...!

Throw some screen mesh over them is a cheap upgrade.

When are they going aluminum bladed fans or am I going to have to machine my own

I've been meaning to do this to my fans. Little blades of grass love making their way into the fans, even with the factory fan grilles on. Maybe I'll finally get around to it one of these weekends

You'd think it would be a no brainer

That wouldn’t fit the planned obsolescence business model..

Just remove the other four blades and that thing'll be running quiet and smooth. Simple as.
