the engine blower fan does not have to do with the engine operating temperature.
it will be activated by the temperature in the engine compartment (big difference).
2 ways to test it:
1. the easy way. use durametric, and activate fan.
2. after a long ride (when the engine is at is pick temp), let it idle for 5-10 min (inside a garage if possible).
the fan should kick in.
beside the fan issue.
if your engine is overheating after pump+stat replacement, i recommend repeating the bleeding process.
