Question Best way to test engine fan clutch

Hello! Since I've never heard the engine fan spool up, even with the coolant going up to 100°, I think that my fan clutch's dead. However, on spinning the fan clutch with the engine shut down, it feels like there's resistance, so I'm not sure that it is in fact dead.

Is there a sure-fire way to test the clutch? Also, how loud is the fan on these cars when it is engaged? The fan on my truck will drown out the engine when it's spinning at speed, and I've always assumed that it would be the same on the car...

Thanks in advance!
