I know my paste on the first time using slightly more than a pea size amount went over the edges a tiny bit but personally id rather have that than not have total coverage, which seems to have made a BIG difference in my temps.

Makes sense
The IHS is a heat spreader by definition. Heat flows from hot to cold, so a full contact is best especially for the direct contact heat pipes. If you put a thermocouple on the edge of an IHS you will find a good amount of heat so heat is being transferred to the edges. The material is not all that thick and probably starting to encroach on a point of diminishing returns but every degree counts.
