I've recently bought an ASRock FM2A75 Pro4 motherboard, except I haven't found the time to assemble the parts yet. So I was checking the board out, when I noticed that there seems to be glue residue along the edges where the back-plate makes contact with the motherboard. It has been a good while since I've last assembled an AMD system (in fact, this is my first FM2 assembly, even though I know that the system is the same since AM2) and the last few used the stock cooler, so I didn't even notice this sort of thing. Now I'm reluctant to use my SD963 in this board...until the warranty period isn't over anyway. And even then. I don't want those SMDs on the back of the board to jump off... My question is, is it glue, or some sort of replacement for dampening foam? EDIT: Upon further inspection and better analysis, it seems to be a plastic-based residue that is there to make sure the metal back-plate doesn't come in contact with the board, avoiding shorts...meh. Got scared for a second there. Still, is it sticky (meaning I have to twitch it a bit to take it off), or does it lack adherence?
