Not quite. The maximum hysteresis is 24kph, so if the fan turns on at 30kph it would turn off at 54kph max. To get it to turn off at 90kph it would have to turn on at 66kph.I now even can set to fan to start at 30 km/h and by another setting to stop at 90 km/h, super !
If you need performance beyond what my circuit provides, without more complexity, then a microcontroller-based approach might be better.
