I just found this on another thread.

For 2 speed motors IIRC the ECU energises SLOW speed for a larger temp span.
For example in the diesel engine:

From 100 Deg C to 111 Deg C = Slow Speed
From 112 Deg C to 119 Deg C = High Speed

I was used to the fan starting at around 97 when I had the 3 speed.

So did another test and fan kicked in at 105-106, and stopped when it dropped to 102.
I had been hitting demist at exactly 105.
So it seems to be fine, hoping I’m not speaking too soon!

As it seems a stronger fan the temperatures drops quickly, stops at 102, yet after its stopped continues to drop to 97.
