Just so we are on the same page, you are talking about removing the black disc, right? Black disk being the heat spreader held against the CPU die by a square plastic piece around the whole CPU package. Then the big metal plate under the keyboard is the heatsink.
On the underside of the black disc I forget what Apple used most commonly, and I would check mine but I am quite certain I squirted some thermal compound under the heatspreaders of my daughtercards after cleaning them out however many years ago. Normally I would want to refer to the disk as an IHS(integrated heat spreader, like what I removed from my i7 4770k!
) but it is not exactly integrated, just more slapped on IMO.
Oh, and my mentioning the TL iMac was incorrect, I forgot about it's rectangular heatsink that butts up directly against the die and is held down by a clip to whatever that daughtercard cage thingy is.
