If you want to make up your own new definition of cooling drag, perhaps you should write an SAE paper or textbook that does so?
Me? I am happy to rely on how the real experts define cooling drag.

The engineer works with whatever is available to stitch the embroidery together.
There's clearly a chain of custody, and each element will have it's own efficiency. Textbook or no, engineers follow the trail, from beginning to end.
If you'll keep re-reading Dr. Wolf, it may dawn on you. He clearly spelled out all the non-aerodynamic caveats responsible for the 911's low drag cooling. The low drag was impossible without these non-aerodynamic technologies.
