Cut 0.125 and it'll be a whole different ball game. The Alu might actually go up in temp(!) but the copper will come down significantly. |
Hmmm, in a basic maze design there's a pretty good chance it'll be the other way 'round.
It all depends on the relative ratio of the material's thermal conductivity vs the rate of thermal convection.
For many waterblock designs, the higher a material's thermal conductivity then thicker you want the base-plate to be.
