Arctic Silver CMQ-22G The high-density, ceramic-based thermal compound

Why would you want to spread some sort of paste on your precious processor?

Why? Because it's good for it.

Thermal compound is necessary to create a more efficient transfer of heat from your computer's processor to its heatsink. Arctic Silver CMQ-22G Ceramique Thermal Compound uses a high-density layered composite of five unique shapes of thermally conductive aluminum oxide, boron nitride and zinc oxide sub-micron particles to maximize particle-to-particle contact area and thermal transfer. Arctic Silver claims that this unique blend provides heat-transfer performance exceeding most metal-based compounds. This 2.5-gram tube will cover approximately 20 square inches, at a layer of 0.003-inches thick.
