I read one of your responses recently regarding heat dissipation and the best materials for doing this. I was wondering if you could respond regarding the use of a ceramic water block as opposed to copper or aluminum for dissipation of heat when used in a closed water pump system with the aim of removing as much heat from the surface of a cpu as possible. Will a ceramic water jacket/block work more or as effectively as copper?

All other features of the design being equal, copper and aluminum are much better conductors of heat than ceramic. Some ceramics are pretty good heat sinks - beryllia, for example, but in general a copper/water or aluminum/water jacket will be more effective than ceramic/water. The heat needs to be conducted to the water for the water to be able to carry it away.

Chances are, however, that the designs of the various devices will differ in more than one aspect. Without knowing all of the design differences, it's impossible to predict their performance. So, you will just have to read the specifications of the devices.
