i would say that's normal behavior. you can tell it's working if you hear the characteristic roar at around 100C. do a search for stu ritter's comments on the fan clutch and a modification to lock it temporarily for summer use.
BTW, one side of the radiator is normally hotter than the other. only sure way to check for cool spots is with a non-contact IR thermometer. if you are uncomfortable with the high temps you can install a "cool harness" which makes the aux fans kick in earlier. if you really want to go nuts you can install a tropical version of the fan clutch - do a search on member bongc36. he has a c36 too over in the philippines and had problems in stop and go traffic. the tropical fan clutch worked like a charm...
