You probably just need to replace the fan. Fans can be replaced with most any 80mm (or same size) fan available on the market. When picking fans, you can choose the amount of noise by the dB (decibel) level they produce.

Either that or there is dust on the vanes of the fan, causing them to be out of balance. Clean them if there is.

Check to see if the vanes are nicked on the leading edge; I had an old computer that one of the vanes on the case fan had gotten nicked fairly bad by something being stuck in it by a previous owner. This caused the case to shake and sound like an old car. Replacing the fan fixed the problem. [I think all the shaking caused by the nick may have not helped the situation by wearing out the bearings.]
