In my experience, as long as ambient is below 90 F, the aux fan keeps the temperature steady at around 82 C even sitting in traffic. Above 95 F ambient, the aux fan cannot keep up in traffic and the temperature would creep up to 100 C and beyond. In those situations, I pull over, shut the engine off, pop hood, let the aux fan run to cool engine down. I will probably add a small electric puller fan before next summer.

My experience too - no fan - no problem for most of the year here in Northern Europe. The capacity of the radiator and the amount of coolant in a 300D is big enough for this.
But it all comes down to low ambient air temperatures and a block free cooling system.
