99.9% PURE SILVER
The Arctic Silver 5 uses three unique shapes and sizes of pure silver particles to maximize particle-to-particle contact area and thermal transfer.
HIGH DENSITY
The Arctic Silver 5 contains over 88% thermally conductive filler by weight. The thermally-enhanced ceramic particles including micronized silver, sub-micron zinc oxide, aluminum oxide and boron nitride particles improve the compound's performance and long-term stability.
