Place a light in line with the fan that will let you know when it is on and slowly adjust the temp setting to where it only comes on when sitting in traffic as when at speed it should not be needed. The 205-200 should be good but it you notice that the fan keeps turning on and then off then back on you might want to set the temp difference a little further away such as 206-198.

My NA 3800 v6 has a t-stat that opens at 195F and the fans are set to the following.
Ambient temp (measured in air intake) 122-119.3F
Fan 1 212-208.4F
Fan 2 221-217.4F
