Not that simple, how much air flows through and how much cooling occurs depends not only on the intake size but the expansion ratio behind, the blockage effect from the radiators, the relative pressure difference at the intake to the exit, etc.
Large expansion ratio and bigger radiators means you're getting more flow and cooling even with a small intake, you can shrink radiators and sidepods but that causes more blockage which generally means you can't shrink your intakes much even with tighter, hotter running package - that's why even when we see teams bring new, tighter sidepods the intake area doesn't change much from the initial setup on the car.
A heat pocket by the turbo when the car is on slow laps/in laps/pitlane might even be fixed by tighter sidepods because you'd have relatively more/faster airflow up there, which is why it's not really a worry unless it's still doing it once they have the new package on.
