You can drop the tube of Arctic Silver. That AC Freezer 64 Pro CPU cooler has excellent MX-2 thermal compound pre-applied to the bottom of the heat sink.
It's easier to install the aftermarket CPU cooler at the initial build than to un-install the stock cooler, clean the CPU and then install an aftermarket CPU cooler later, possibly having to take the motherboard out of the case.
