Enthusiast CPU Thermal Compound: Premium Zinc Oxide based thermal compound for optimal thermal performance. Cools your CPU and GPU: install new, or replace existing thermal compound on your CPU and GPU to improve heat transfer and lower temperatures. Improved CPU cooling: ultra-low thermal impedance lowers CPU temperatures vs common thermal paste. Installation Made easy: An included application stencil and spreader take the guesswork out of applying XTM50 to your CPU cooler. Filling the gap: xtm50’s low-viscosity allows it to easily fill microscopic abrasions and channels for peak thermal transfer. Long Service Life: XTM50’s high-stability liquid compound lasts for years with no drying, cracking or change in consistency. Safe For You And Your PC: Non-conductive and contains zero volatile compounds.
