Okay just found a generic article that talks about a thermal element on the front of viscous fans that opens and closes valves internally to the fan in response to temperature

Is it theoretically possible to over heat an engine when the vehicle is at standstill or little air is coming in through the rad? Surely no or little air would affect the fan?

Or does it work on the ‘ambient’ engine bay air temperature?

So based on that, theoretically is it possible to over heat and engine of the vehicle is stationary and no air (or little air) is coming through the road?

at idle the unlocked turning fan is enough to keep it cool ,maybe not in serious hot conditions

The fan will suck air through the rad anyway, they always spin, the hotter it gets the more it locks up.
