Well,I researched for the holy grail of thermal mastics, and I found it.It
is called Artic Silver 5. www.articsilver.com is the site.It has a ton of
info.Search this in yahoo, and you can get actual testomonials and user
talk. It costs $6.50 +$5 shippping for 3.5 grams. The 1/4 the oz tube of
radio shack stuff I used, was $1.99,and I only needed 1/2 a tube. They say
to aply the artic silver 5 at .003 thickness.I think 1 tube will do it. It
tis said that theis will improve conductivity 3 to 12 degrees over the zinc
oxide type compounds.
