on my series 60, the two speed hydraulic fan kicks into high speed (sounds like a jet turbine) at 205 degrees, then it will usually quite quickly move down to the low 190's or less.
i have done some pretty spectacular grades with mine and never overheated. the ddec will protect itself. so 205 is not high at all.
the challenge on the forum is what size of grades are we talking about. i live where to get out of az you have to climb to sometimes well over 7000 feet. many folks in the east think a tough grade is climbing from sea level to 800 feet....ha
