Question:
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?
Replies:
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.
