I'm saying so because I'm afraid heat is being forced to spread laterally and not both uniformely laterally and upwards throughout the pins. Keep in mind that you could also lower your baseplate when making higher fins/pyramids which would further increase performance. The only way to know for sure is to experiment or simulate using a simulation program.
There really is no other pin height for 2 reasons. One the tooling and 2 the base will be to thin and collapse under mounting pressure. Can't make the base thicker because the heat will spread out to far. It is as perfect as it is going to get. Once again I set my goals of what materials and tooling to be used before I started and they will not be changed. That however, doesn't mean this is the only block I am working on and could very well just be one of a few. Price/Performance is all I will say for now.
