I would also point out that if you look carefully at the VFD manuals you will usually find a chart or formula for how much heat is generated at less than full load. It can be substantially less than at full load. If you know what the motor NP FLC is you can use that to find out how much heat gets generated at that current instead of using the worst case of full load of the VFD.
