I can imagine some residue left from whatever process was used to manufacture heatsink/waterblock interfering with performance.

Bill recomends cleaning between test runs using xylene.

Otherwise, this fellow appears to have used a good thermal paste, and we (here) all know how much of an impact the TIM joint has.

Copper will also "absorb" things. One of the problems with casting copper blocks as they can leak. I belive TIM will absorb into the copper a little. But will that turn into a clear liquid and then smoke? Easy experiement if someone has a heatsink laying about. I think I got some somewhere will look into it a bit later.
