Radiator fan On Temprature

[miategra]

Guys Hi,

For the past 2 years because of the pandemic and my hard working time I was able to do just 700kms with my bike.
Last week a had a visit to dealer for yearly servicing.
After service I realized something; please correct me if I'm wrong. Where or at what temperature does your radiator fan kicks in?
As I remember it was on when the radiator temp reaches 103~104 degrees celcius right?
After the annual service now my bike (Gen1) powers up the radiator fan at 100 degrees celcius. I think BMW had updated the oem ecu sw. Can you correct me? Because I'm not sure if I'm remembering right.

Gen 1 or 2? I assume Gen 2, Gen 1s came on at right around there, but if it comes on earlier that's better, i always found 103 a little high, if anything should be even lower.

The dealer I use said only get concerned if the temperature hits 110⁰C.
My fan comes on at 103 and goes off at 97. (Gen 1)
