Other than appearance, is there any real difference between the Blue Anodize and Black Anodize PolarFLO blocks, or for that matter, the chrome plated or gold plated top?
I never really thought that the top of the waterblock mattered much, since the primary heat exchange takes place at the waterblock base and the radiator.
If the top of the waterblock does serve a heat dissipation purpose, has PolarFLO ever considered making something like a combination heatsink and waterblock, so heat could be disapated from the waterblock itself more efficiently, in addition to having heat carried away by water? Why wouldn't a copper top be offered, if heat dissipation from the top of the block matters?
