These are normally quite noisy when the thermostatic fan kicks in. Believe it or not, you can hold the fan with your hands as someone else starts the engine, assuming the clutch is not seized. I've watched people do this but I'm too chicken to try it myself.
As the engine warms up, you will feel the increasing tug of the fan trying to turn. Some vehicles make more noise when the fan starts to move more air, some make less noise as the clutch slippage decreases.
