The problem is the way Apple designed it - the “wings” on the heatsink act as springs and they apply a pull-up pressure on those stands constantly, eventually rip them off the board. You can use super glue to re-attach it, but bend the wing down slightly until there is no gap between the hole and the stand like it was before to eliminate that pull-up pressure. As long as all four screws are tightened down, the heatsink would make perfect contact. I just did mine.

There is no stud. That crap is just glued onto the board.
