Yes the paste should be OK.

You need to ensure that both surfaces are spotless and try avoid scratching them, then apply a thin smear to one surface only.

Why use heat sink paste?
If you look at the surfaces under a microscope it will look a bit like the moons surface - all cratered, obviously where these uneven surfaces are there will be no metal to metal contact, there will just be an empty void.

What thermal paste does is to fill these craters in, the heat will then flow through the paste particles rather than across an empty hole.

It can be said that using no paste at all is far, far better than piling it on as though we were greasing a gear box.... the secret is just to use a smear, use too much and we make the heat transfer worse.

I used the moon for want of an easy explanation - obviously the surfaces isn't that bad, but you can see what we are trying to do.
