Check the viscous fan hub isn't "frozen" and spinning the fan at full speed at all times. These viscous couplers have a number of different failure modes... mine had a bearing failure but they sometime don't spin or sometime always spin. The coupling should be temp dependent and not spin (much) when the engine is cold.
