A thermal conducting material with higher thermal conductivity for a given low viscosity is shown. Carbon fibers are added to the thermal grease to promote thermal conductivity. The carbon fibers are also not highly electrically conductive, reducing the danger of short circuiting due to misapplication...http://www.google.com.au/patents/US6651736?utm_source=gb-gplus-sharePatent US6651736 - Short carbon fiber enhanced thermal grease
