Cheers

Completely normal for a standard two-speed switch on an Escort. For emission's purposes, the fans try and hold the engine as close to 100°C as possible in traffic. The first (slow speed) comes on at around 93° and the second (high speed) at around 99°.
Fit the Sierra switch or Stu's - both of which are single stage, and it will come on full speed at around 93° and should hold the temp at that in normal use.
Due to the high pressure the cooling system works at (even more so if you have an alloy tank and increased pressure cap), and providing you have a 50/50 mix of antifreeze, the fluid won't boil until well into the mid 120s°C, so 100-110°C on track is nothing to worry about
