It should give some but, it's not quite spn freely. So it's not locked at the clutch. Are you sure its on all the time. IT will spin with some slip normally and kick in with a lot more roar noise when engaged. When you first start it cold it kicks in and make that loud fan noise then slowly gets quiet as it not fully engaged until it warm to the right temp.
In other words it should be spinning some all the time but, not locked in all the time.
