Premium Zinc Oxide based thermal compound for optimal thermal performance. Install new, or replace existing, thermal compound on your CPU and GPU to improve heat transfer and lower temperatures. Ultra-low thermal impedance lowers CPU temperatures vs common thermal paste. CORSAIR TM30's low-viscosity allows it to easily fill microscopic abrasions and channels for peak thermal transfer. Once installed, CORSAIR TM30's high-stability liquid compound lasts for years with no drying, cracking or change in consistency. Non-conductive, non-toxic and contains zero volatile compounds.
