Thanks I just figured it out. On one side of the backplate there is insulating tape on the FEET. On the other side of the backplay there is insulating tape on the BODY of the surface.
Its hard to explain without a picture, but in other words there is insulating tape on BOTH sides of the backplate, so depending on what mobo socket you use, insulating tape will touch.
I feel pretty stupid for posting, but what happened is I install the backplate, then read the note, then look at see tape on the wrong side.
I will leave this post up for anyone else who has a tendancy to overthink things =x
