I don't know how much of a "cooking" effect there would be (nor do I
care), considering that this temperature is no warmer than a hot summer
day in many places. Also, the warm fat begins to cool instantly when
added to the dried meat. Indeed, if you wanted to hasten this, I
suppose you could refrigerate the dried meat first. One reason why it
tastes like candle wax is that candle wax is, in fact, mainly stearic
acid. Same for crayons, a traditional grade-school treat. You can buy
bulk stearic acid from chemical supply companies. It's very cheap. It
comes in granules or flakes.

The more liquid a fat is, the more unsaturated it is. Kidney fat is
hard at room temp because it's so saturated. The more unsaturated a fat
is, the more prone to oxidation spoilage it is. For the native
Americans, the whole point of pemmican was that it was a food that could
be made in bulk and stored for the winter or for long overland travel in
the warm seasons, without fear of spoiling. If you use more muscle fat,
it might be a good idea to keep the pemmican refrigerated until you eat it.
As others have pointed out, muscle fat is a symptom of obesity. You
wouldn't find much of it in wild animals. Subcutaneous fat, kidney fat,
hump fat, are a different story.
A reason why cold-water fish are so high in PUFA is that if they
weren't, the cold water temperatures would cause their bodies to harden.
