Nate, it's the 3/8 EV foam on each side. It's a little too thick, so I had to carve out a section so it would fit against the NB heatsink cooler.
@John, yea I know. Now you...you're out of control my friend, LOL. No, really, I wish I was doing what you are doing. It shouldn't be too hard to get off, as there is a layer of eraser below the foam, and a number of coats of plasti-dip below that. No sticky side of the foam is touching any raw component.
ok, almost there. time to test condensation one more time. I was going to fire it up on the 780i board, but it won't fit at all, and I don't want to mod it for the 780i, since I'll never use it on that board anyway. -23.4C now...almost time to turn the pump on.
