Arctic Silver 5 High-Density Polysynthetic Silver Thermal Compound, 12 grams Tube. Thermal compound is necessary to create a reliable transfer of heat from your computer's processor to its heatsink to keep your CPU from overheating. Arctic Silver 5 thermal compound does this with three unique shapes and sizes of pure silver particles to maximize particle-to-particle contact area and thermal transfer. It's optimized for use between modern high-power CPUs and high-performance heatsinks or water-cooling solutions. This 12-gram tube contains enough compound to cover at least 50 small CPU cores, or 20 large CPU cores, or 7 to 15 heat plates.
