if I use a leopard 4074 2000kv + 3s + correct gearing only will have 22-25k rpm .... and I will have the same top speed and lower temperatures than the 4065 2700+3s ....... the difference is will have more spent of energy and +70gr.....

yes what you listed is impt to keep components cool and to obtain desired speed. RPM does play into the efficiency of the setup. Correct gearing/motor choice will lead to a cooler running setup as well.

If you can obtain a cool running setup with a lower RPM, then you get the most run time out of your system... which is what I strive for in all my rigs.
