IBM thinks so. Read it, and while its not exactly what you are talking about its close. Any way the 3 biggest things that affect heatsink performance are how well the heat gets from the cpu to the heatsink (thermal paste or other), total surface area, and how well the material absorbs, conducts and gives off heat. copper is really good at absorbing and conducting heat, but not nearly good as aluminum at giving it off. Thats why we are seeing more of these hybrid Al/Cu towers now. There are other materials that are better than copper, silver for instance. Also an active heatsink is better than a passive, as the overall goal is to get the heat into the air. A fan will provide more cool air for the heat to go into, and it will get the hot air moving away form the heatsink.
