I have a full sized ATX case with several fans, including one on the door/removable side. This fan makes the "door" rattle or vibrate loudly when the fan runs at full speed, such as at startup. I can stop the rattle temporarily by placing my hand on the "door", or pushing an object next to it.
Do you have any suggestions for a permanent solution?
Note: The "door" in question is a slide out panel with two twist screws at the back to hold it in.
