I just installed a Noctua NH-C12P SE14 fan to my pc and i actually forgot to put the vibration pads underneath it, are those pads really necessary? I can't hear or feel any vibration in my pc. Reason i'm asking is because i have a mini-itx case and it was a bitch so install and i don't want to take it apart and put it back together if the pads aren't necessary.

Yeah, the pads look and feels like silicone or something, 4 rectangles.
