Arctic Silver 5 High-Density Polysynthetic Silver Thermal Compound AS5-3.5G

Arctic Silver 5 is optimized for use between modern high-power CPUs and high performance heatsinks or water cooling solutions. Arctic Silver 5 uses three unique shapes and sizes of pure silver particles to maximize particle-to-particle contact area and thermal transfer. Arctic Silver 5 also contains micronized zinc oxide, aluminum oxide and boron nitride in addition to the silver. These thermally-enhanced ceramic particles improve the compound’s performance and long-term stability. Arctic Silver 5 does not contain any silicone. The suspension fluid is a proprietary mixture of advanced polysynthetic oils that work together to provide three distinctive functional phases. As it comes from the tube, Arctic Silver 5’s consistency is engineered for easy application. During the CPU’s initial use, the compound thins out to enhance the filling of the microscopic valleys and ensure the best physical contact between the heatsink and the CPU core. Then the compound thickens slightly over the next 50 to 200 hours of use to its final consistency designed for long-term stability. Contains 99.9% pure silver: 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: Arctic Silver 5 contains over 88% thermally Conductive filler by weight. In addition to micronized silver, Arctic Silver 5 also contains sub-micron zinc oxide, aluminum oxide and boron nitride particles. These thermally-enhanced ceramic particles improve the compound’s performance and long-term stability. Controlled Triple-Phase Viscosity: Arctic Silver 5 does not contain any silicone. The suspension fluid is a proprietary mixture of advanced polysynthetic oils that work together to provide three distinctive functional phases. As it comes from the tube, Arctic Silver 5’s consistency is engineered for easy application. During the CPU’s initial use, the compound thins out to enhance the filling of the microscopic valleys and ensure the best physical contact between the heatsink and the CPU core. Then the compound thickens slightly over the next 50 to 200 hours of use to its final consistency designed for long-term stability. (This should not be confused with conventional phase change pads that are pre-attached to many heatsinks. Those pads melt each time they get hot then re-solidify when they cool.) Absolute Stability: Arctic Silver 5 will not separate, run, migrate, or bleed. Thermal Conductance: >350,000W/m2 °C (0.001 inch layer) Thermal Resistance: <0.0045°C-in2/Watt (0.001 inch layer) Average Particle Size: <0.49 microns <0.000020 inch Extended Temperature Limits: Peak ?50°C to >180°C Long-Term ?50°C to 130°C Performance: 3 to 12 degrees centigrade lower CPU full load core temperatures than standard thermal compounds or thermal pads when measured with a calibrated thermal diode imbedded in the CPU core. Coverage Area: This 3.5 gram tube contains enough compound to cover at least 15 to 25 small CPU cores, or 6 to 10 large CPU cores, or 2 to 5 heat plates. At a layer 0.003″ thick, the 3.5 gram tube will cover approximately 16 square inches.
