To be more helpful, your fan doesnt have a fuse cos it isn't electric. If its overheating (assuming gauge and fan is working properly) you have a problem with something else like water pump or thermostat or maybe something more expensive like blocked radiator or cracked haed
 
Viscous fan should roar on startup and then quieten down after 30 seconds or so depending on temperature. After it quietens down you should be able to stop it with a rolled up newspaper. When it gets hot it should start to roar again as it locks up and it will shred your newspaper.

Coolant leak. Check drivers side carpet by transmission tunnel for dampness. If so check heater o-rings in pipes where they go through bulkhead. Check all rad hoses. Check the radiator itself. Check little pipe from rad to expansion tank is free and cap is screwed down properly on expansion tank. In rare instances the head is cracked.
