At what temperature does the fan turn on?

The fan starts when gauge exceed the half، and stop on the half.

But before months ago, the gauge lower the half, and never reached the half.

By the way, on the road while I drive it, the temperature gauge is lower the half.

Dash board temperature gauges aren't really gauges any more they indicate what the instrument panel computer wants you to see. After a about 3 miles or less even in cold weather it should go on to "N" and stay there only when stopped in heavy traffic should it rise to just above "N" and the fan start on slow speed.

Only way to check if everything is working normally is to connect an OBD scantool that reads live data and graph the temperature in normal driving
