Occam's razor

Possible neither "volume of flow" nor turbulence should be maximised to get the best performance from "available head"
Using Kryotherm for designing a thereotical wb with a 50x50mm baseplate for an "available head" of 30KPa(10.04 ft water) the best designs I came up with were laminar flow.
For example for 90 fins this would be my choice from one Turbulent and two Laminar ::

Note that the K/W( =C/W) is for cooling a 50x50mm heat source.
