The savings is both in reduction of electrical load and minimal savings in weight due to deletion of one fan.

My P307 has A/C (the condenser is right in front of the radiator) and only 1 fan. The fan kicks in when the coolant temperature reaches 98C. If A/C is active, then the fan keeps coolant temperature below 82C, which is a bummer if you are trying to keep the engine running hot for FE.
Ideal would be if the A/C condenser and radiator were independent (not in front of each other, but side-by-side and walled off), with their own openable grille blocks and fans. But then you have the weight penalty and the circle closes.
