Could be that you just have some dust built up on the heatsinks, which causes the computer to run hotter, which in turns causes the fans to kick up. Pop open the sides and see if it's dusty. Anyway, no a loud fan does not mean you need to replace it, if you manually adjust the fans on an iMac it will sound like a jet.
