Energy stored in the bp is irrelevant, once the rig achieves a balance point (my mistake).

A restriction, wether it's part of the barb or not, will achieve better cooling, because it creates a highly turbulent flow, which is great for improving the heat transfer to the water, as long as the accelerated coolant is located in a critical area.

As I remember, G_F, you and I went over this, some time back, but in your particular case, removing the nozzle gave you better performance. So again, the fin design is critical, because there may be some instances (Cathar for example) where an impingement may yield better results.

The transfer rate of copper does not change but the cunduction path is shortened by the thinner baseplate.
..................
Energy stored in the baseplate is what determines the heat of the die, if it balances out at a lower temp in the baseplate then the die will be cooler.

Agreed

That was in a different block and the tradeoff was in the negative direction for that design, higher overall flow was more beneficial.
A restriction is built into the base of my EQ design which increases the velocity at the center of the bp.
