Xigmatek PTI-G3606 Thermal Compound Extended Temperature limits: Peak: -20 to 180 Outperform to standard thermal compounds 4 to 10 degrees lower CPU full load core temperature. The high-density, specifically designed for modern high-power CPUs and high-performance heat-sinks or water-cooling solutions Silicon-based thermal grease has moderate thermal conductivity. Not electrically conductive, can't cause problems if it contacts the pins of an IC.
