The important thermal resistance is not likely to be the adhesive (its path length, the thickness of the glue, is short), but rather the package of the IC. While 'loaded' adhesives have better conductivity (we've used copper powder/epoxy mixes here, for our cryostat work), the plain ol' gunk from the tube is entirely adequate. John Whitmore
