Premium zinc oxide-based thermal compound for optimal thermal performance 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 in your CPUs heat spreader and coolers contact plate, for maximum thermal transfer area. CORSAIR TM30s high-stability liquid compound lasts for years with no drying, cracking or change inconsistency, so you don't have to worry about changing or re-applying thermal paste periodically. TM30 is non-conductive and contains zero volatile compounds, making it safe for both you and your PC.
