Whilst on hiday recently in France it was very hot but I dont think I have ever heard the electric fans operate.
However the temp gauge simply sat at the normal mid scale position.
Surely the fans should have cut in at some time ? Or is the rad so big they are not needed?

Never once heard mine either. Temp gauge sits smack in the middle and no signs of overheating.

If it ain’t broke springs to mind as I’ve never given it a thought.

Mine sits just below half during normal driving and rises to exactly half way under load, climbing hills etc.
Not aware of fan operating when driving but I have heard it from time to time when I stop.

I can’t give an answer to your question but on the X250 the first fan kicks in at 95, and stops at 90. Then you have the second fan which kicks in at higher temps. So they like run these warm.

In 6 years the fans on my 2003 2.8jtd have come on once....I had driven at 70mph'ish 🤐 for about 2 hours in a hurry at night and then had to sit in stationary traffic
I may or may not have proved, officer 😉, that the heki spoilers are good for 95mph 😏
Even this years heatwave didnt put them on

IMO any vehicle should be designed with adequate flow through cooling from the movement of the vehicle.
The only time I would expect a fan to start would be if the vehicle was to stop or possibly on a very long incline at slow speed.
The exception is where air con is fitted and that usually has a separate fan specifically for aircon.
