100C shouldn't be a problem. The system is pressurised to 1 Bar so it should stand about 120C before boiling.

The fan comes on at different speeds and you are correct, you cant feel it and can only hear it on max.

My w202 c230k hovers around 85 - 90 ish, but in traffic with a/c on it has got to about 105 . Not a problem.

Water Temp

I had similar worries, previous thread indicated the fans are viscous, not on/off type which I was used to and you have same worries.
I fitted new Stat because temp was always sub 80, temp now runs 85-90 all time, with Caravan on back lives nearer 95-100 but seems perfectly happy.
