base thickness
Here is a graph of thermal resistance in copper as a function of thickness.
There has been some question of how thick the base of a waterblock should be between the core and the water.
We have to remember that some of what a waterblock does is spread out the heat of the core so that we have more surface area to work with. If the bottom of the wb is thin the advantage of using copper as a heat spreader is diminished.
I can't remember exactly where I got these results, but it was at a university site with a java tool.
Just some food for thought!
