This is exactly what I have in my turbodiesel: Without grille blocks it barely keeps 78°C, with both blocks it crawls up to 90°C more often. Fan turns on at 97°C and cools to 89°C, so haven't had problem with overheating. Also, at 90° I see slightly lower fuel consumption at idle, like 0.48-0.52 vs 0.52-0.54 liters per hour.
You will notice that as you drive more efficiently, the engine will not be as hot. This is because you are wasting less energy as heat and using more to move the vehicle. You should start thinking about insulating the engine bay, this will also keep the engine from cooling off too fast, so it will be warmer when you start again after shopping, for example.
