As far as thermal grease goes, the Tuniq TX-2 is at the top of the list as it has an advantage over its competitors. That advantage is the way it spreads out over the processor. Some thermal compounds spread out like cold butter and get all clumped up, but the Tuniq TX-2 spreads out smooth like peanut butter and doesn't clump up at all. One small ribbon of paste will spread out evenly and easily over the processor.
