3.5 g


Three unique shapes and sizes of pure silver particles to maximize particle-to-particle contact area and thermal transfer.
Contains over 88% thermally conductive filler by weight.These thermally-enhanced ceramic particles improve the compound's performance and long-term stability
Ensure the best physical contact between the heatsink and the CPU core.
Will not separate, run, migrate, or bleed.

I heard good things about this thermal compound, and it's pretty good for the money, though it does have a lengthy break-in time.
