Do I still need thermal compound?

I bought a 2nd cpu and a heatsink direct from dell. The heatsink has a greenish sticker in the center. it doesn't seem to have a layer I can peel off so I'm wondering if this is supposed to be thermal tape and if I'm safe to leave it and not peal it off and use fluid compound instead. This is my first time installing a cpu/heatsink.

    It should be the thermal pad but usually there is a plastic pad or something covering it on the heat sink so if it had something in the packing material that fell off or you took off then it is for sure. Does a corner feel tacky at all? If you don't trust it you can clean it off but you will need to get some compound if you do. It sounds like it is the pad so you are most likely good to go.

    Robbie,
    I've seen heatsinks for Dell notebooks (C-Latitudes, 8xxx Inspirons) which had a soft metal contact surface instead of using thermal compound.
    The metal was somhow like lead or tin, but a lot softer, you could scratch it with your finger nails even if you used no force at all.
    The surface looked  stripy and the stripes (dark/light) had a slightly different height.
    New parts WERE covered by a green transparent peel off plastic.
    Since plastic is not a good thermal conductor, I'd peel that egg before eating it...

    Well, my friend had some AS5 left over so I scrubbed the heat sink and used the compound instead.
