Nope
The ECU has to see 206+ before it triggers the fans at low speed.
If you have a OBDII scanner that shows engine coolant temp.
Hook it up and just let the car idle while you watch coolant temp.
When it reaches 206 the low speed should kick in.
Then you can compare your dash temp. gauge with what the ECU is seeing.
May give you a better idea of when your fans should kick in while driving and just seeing your dash temp gauge.
