Fan switch , what temp should it open?

[ADRIANFARINA]

mine is faulty , bought a new one.
it operates the fan only on the 3/4 of the temp gauge for about 5-6 seconds and turns off.
what is the temp range it should be?
on the temp gauge , is 3/4 ok?
thanks

The fans turn on at 195*. Generally, they should be turning on before the temp gauge reaches the halfway point.

195*F should be 90*C

it opens way far after halfway.. :/
