The quest for the highest clock speeds will never stop, and neither will the quest for the best performing thermal compound. OCModShop has taken a look at the TherMax Tech XFlux-GA, which looks to be an all around winner with price and performance.
"Thermal compound is used to fill these microscopic gaps with a material that conducts heat, but is pliable enough to fit in all the nooks-and-crannies, creating a complete physical surface that heat can pass through. Over the past few years there have been several different thermal paste technologies, each of them trying to efficiently transfer heat away from the processor. One of the best electrically conductive metals is silver followed slightly by copper."
