My understanding is that some tiny portion, like 1-2%, is actually used in a meaningful way to do calculations to do what you want, but that could incorrect. Or it may be that that tiny portion still inevitably turns to heat, just indirectly somehow. I'm not sure, though, you could be right.
All of the energy that does calculations gets turned into heat. The only energy that doesn't get directly turned into heat is the mechanical energy produced by the fans (which ends up turning into heat), and the electromagnetic radiation (which also ends up turning into heat).
If the calculations didn't convert energy into heat, a computer would essentially use no power. You can think of a computer like a really complex wire. The power consumption you see is actually the heat loss of that wire. The less heat you lose, the more efficient the wire is.
How did you go from 10% to 1-2%? Please don’t use such precise figures when the source is clearly your ass.
