Recently I ordered a new side panel for my XPS, to see if that would alleviate the buzz issue I've had with this PC since I received in early March. It seemed to work for a day, then the buzz returned. Now I've left the panel off completely, and no buzzing or noise issues, except a tiny bit when the PSU ramps up, but nothing like before with the panel on.

What I'm wondering is, if anyone has had this issue with their XPS 8930 or even 8920 or 10, as I believe they have the same quick release side panel also. If so does anyone have any pictures or examples of what might dampen this vibration between that case and the panel, example felt pads. I need to know where to place them before I start trying the dampening next for that panel. Somehow the panel has just enough play in it to take on vibration from the case. Right now without the panel on, very silent. This pretty much rules out any other issue causing it. Any examples would be very helpful for when I try to put the panel back on. Thanks.
