Sounds good to me  |
Some trucks achieve a similar result by using a thermostat to control the opening of the grille slats ahead of the radiator.
At low temperatures the grill opening is small and at higher temperatures the opening change to allow more airflow.
Rolls-Royce used the same principle as far back as the 1920's for the same reason.
