Apple processor card and thermal paste

Hi

I'm planning to upgrade the processor in my QuickSilver over Easter (single 800 MHz, no L3 cache). In order to avoid any third party firmware patches needed to recognise the processor type and any software patches needed for the correct speed to be reported etc, I've ordered a processor card pulled from another QuickSilver (dual 1 GHz, 2MB L3 cache). However, this means I have to reattach the heatsink that's supplied with the 'new' card.

Is thermal paste between the processors and heatsink necessary? Assuming some was used before, am I right in thinking I just clean off the old and apply some new? If so, do I apply it to the 'core' only (the dark blue centre bit with the numbers on)? Arctic Silver seem to sell a two part cleaning kit and thermal compound, is this recommended?

I guess I'm mainly just looking for some confirmation that I'm going about it the right way and whether there's anything to avoid.

Many thanks in advance...

If the heat sink has a thermal pad on it (instead of paste residue), you should carefully remove it (use a plastic putty knife to prevent gouging the aluminum). Then, clean the surface with alcohol, prior to installing it on the processor. The instructions will advise against applying too much compound. It's important to apply just enough, because it will spread, as the heat sink is clamped down over it.
