Arctic Ceramique is a high-density, ceramic-based thermal compound specifically designed for modern high-power CPUs and high-performance heatsinks or water-cooling solutions. Ceramique does not contain any silicone. The suspension fluid is a proprietary mixture of advanced polysynthetic oils that provide superior performance and long-term stability. Ceramique uses a high-density layered composite of five unique shapes of thermally conductive aluminum oxide, boron nitride and zinc oxide sub-micron particles to maximize particle-to-particle contact area and thermal transfer. This exclusive combination provides performance exceeding most metal based compounds. During the system's initial use, the heat from the CPU lowers the viscosity of the compound to enhance the filling of the microscopic valleys and ensure a minimum bond line between the heatsink and the CPU core. Then the compound thickens slightly over the next 100 to 300 hours of use to its final consistency designed for long-term stability. Ceramique is engineered to not separate, run, migrate, or bleed. Ceramique can easily be cleaned from CPUs and heatsinks with isopropyl alcohol or ArctiClean 1 Thermal Material Remover followed by ArctiClean 2 Thermal Surface Purifierany acetone and a bit of careful rubbing. For Heatsink cleaning you can use the ArctiClean 1 Thermal Material Remover followed by ArctiClean 2 Thermal Surface Purifierany or use xylene based products (Goof Off, some carburetor cleaners and many brake cleaners), mineral spirits or high-purity isopropyl alcohol. This is a 22g tube.
