I used Arctic Silver for years. Good stuff, but 2 major downsides that made me switch ti mx-4: first is cure time, it takes a month for Silver to cure and reach it's final stable temps. Second was that (in my experience), it tended to dry out quickly. Like 3-5 years. Mx-4, I've never needed to reapply, and the few times I've checked, it's still slick and strong.
