Reinforcing electrical ceiling box

We are replacing a light in a bedroom upstairs with a small ceiling fan. While reading the directions it suggested that we reinforce the fan ceiling box. So we looked up how to do that and decided to proceed. I spent about 30 very long min in the attic while my wife taped the area in room so I could find the box through the insulation. The box is not accessible as it is in an area too narrow to get to. We decided as the box was exceptionally strong and would not move even after I pulled on it to proceed with the instillation. We did however give the box one more long screw for safe measure. The fan is working fine and is holding. Is it always necessary to reinforce a box? Should I be worried?

The box is probably not fan rated. If it has thin mounting ears using 8-32 screws it is not fan rated. It is not so much a weight problem as a a fixed load vs dynamic load of a fan. You can get retrofit kits that mount from below.
