Even though I have a half tube of AS Ceramique left, I just ordered a tube of Nanotherm PCM+ from IThinkPC for my new Zalman CNPS7000AlCu. Even if temps are within 1-2C, Nanotherm being slightly cooler, the piece of mind that I know my application was perfect is worth it. Maybe the density throws me off compared to thermal pastes in the past, but I always feel like my Ceramique application isn't quite up to par for some reason. I'll be sure to post results of both the PCM+ and the HSF when I receive them.
