To a first approximation, if the fan is going (and using energy) because the CPU is running hot under load (using energy), doesn’t that give you a hint about battery efficiency?

Two laptop model with the same CPU can have big differences in thermal design, which impacts a lot the fan noise but battery efficiency only in a marginal way.

  Sounds like you’ve just supported the point about fan noise being a good approximation for battery efficiency.
