I think if I remember correctly from my 190D, the main fan was engaged at 100C & cut off once the temp lowered to around 90C-95C. High speed aux was set to trigger at 110C. Perhaps you have a bad or incorrect temp switch installed?

As installed on a 601 I've never been really happy with them as they don't turn on until the engine is quite hot. I've thought about sneaking a lower temp sensor (there are 3, one for the gauge, one for the fan clutch, one for the aux fan) to see if I could get it to lock up sooner.
