If it's broken, it depends on what happened internally. They can either
seize internally (making it harder to turn or locked up) or break internally
where it will be very easy to spin. I have an '01 Dakota sitting in my
stall with a broken (internally) clutch fan. I can spin it with one finger
and the engine IS at operating temp. Customer complaint: running hot and
A/C not cooling properly.

Whether it's fully "engaged" or not, it WILL be harder to spin when the
engine is at operating temps than when it's cold. No ifs, ands, or buts,
about it. Been there done that. On my old '99 R/T I had, anytime you were
driving in traffic with the A/C on, the clutch fan would always engage and
you could hear it roar pretty good. But like I also said, there is a way to
"test" it even when cold by checking how far it spins.

No offence Brian, but the fan clutch should not be "engaged" at "normal"
operating temps. It should always move relatively easily (although not
necessarily what you might call a "spin") until the radiator temp it senses
is high enough to basically lock it up to where there is little to no easy
turning of it by hand. I'd have to look in my FSM to tell you exactly
what temp that might be but in all my years of experience my fan has only
"engaged" (I could hear the roar clearly) when sitting at a traffic light in
95 degree temps with the AC on.
Just my .02.
