This guy sandblasted his homebrew GPU cooler to clean it up, "...and further provides a micro-porous surface for enhanced heat transfer."
My experience with sandblasting is that the pressure would be enough to tear the hell out of the fins, and to do at a low enough pressure the blaster nozzle would have to be too big to work well. Beadblasting would give a similar finish, and could be done at a fairly low pressure. Would beadblasting the fins improve this great heatsink?
