Thinking about changing to Fan 1 on at 200 F off at 196 F. Fan 2 on at 206 F off at 202 F.

I live in the mid west summer temps can run in the 100 F to 0 F in winter.

Any body got any input on what is the best temps to set Fans at.

Your new settings are pretty close to where mine are set and even on a 100 degree day in traffic my temp is steady at 200 degrees. Both fans run the majority of the time but it's not a bad thing to have more air circulating through the engine bay.
