There is a fan drive circuit in these that will control the fan speed depending upon the load on the amp. It sounds like this citcuit is defective, This unit should be sent in for service. Crown units are not the easiest to repair and I would not suggest it be attempted without prior experience. This should not be an expensive repair.
