The first ceramic-based, polysynthetic thermal compound for use between modern high-power CPUs and high performance heatsinks or water-cooling solutions. Arctic Alumina is sold in 1.75 gram tubes. This is enough compound to cover at least 25 to 35 small CPU cores, or 9 to 15 large CPU cores, or 4 to 8 heat plates. At a layer 0.003" thick, it will cover approximately 24 square inches. Although lighter per tube than Arctic Silver II due to its use of ceramics rather than silver, each tube of Arctic Alumina actually contains slightly more compound by volume than a tube of Arctic Silver II and will cover MORE area.
