I did a "test" during my vacation trip and it appears that the 1cm wide slits in my grille block are still good for something at highway speeds (~95 km/h): On the way out I had the lower grille block closed (upper grille and IC unblocked) and saw coolant temperatures around 91-92°C with outdoor temp ~21°C. On the return trip it was much hotter (32°C), but the engine was cooler (81-82°C) with the lower grille unblocked.
More details about the test here.

BTW My grille block now has more openings than on the old picture in the first post.
