Fan Clutch

[buddy]

Has anyone noticed the roar that comes when the fan clutch engages. It seems like my clutch fan doesn't want to disengage as rpm's increase.
At high rpm's the clutch will finally disengage and everything is fine until you stop and accelerate again. I've replaced fan clutches before, but usually on high mileage vehicles.
I have no overheating problems, temps always at 210. Manual says that's normal operating temp..I would perfer 180.

What you think? Normal for this vehicle with higher coolant temps? Clutch fan going bad?
