Why do you think this is SO complicated? Heatsink design is trucky yes, but the basic understanding of heat transfer is simple.

Because, I've done some designs in the past and most of them didn't pass mil specs due to the little gravity effects and other heat related problems. And if it is simple then why there is no simple heatsink for CPU, but we see all kind of crazy designs flying around while copper and aluminum are still have the same properties with air included.
I didn't said that it is less efficient, I said it is complicated and has its limits due to its better efficiency in limited range of applications or temperatures.
