So i recently replaced the alternator, water pump, and fan clutch (200 miles ago) due to a whining noise after replacing these items the whining ceased. However just the other day the whining came up again and I'm sure it is the fan clutch. I was wondering if there is a problem causing it to go bad or how they go bad in the first place? I drive my car hard but the fan clutch is also brand new so not sure what to do

Are you sure its the fan clutch that is whining, could it be anything else? I don't believe I've personally ever heard a fan clutch whine. When they break they tend to just lock up and you're fan will always be on. (and the car will sound like a jet driving down the road).

Maybe belt pulley bearing .
