If its under warranty then backup the data on it, wipe the drive, and send it in for repair.
If its out of warranty, open up the enclosure and measure the width and thickness of the fan and Make sure the fan uses a standard connector then google for a replacement. Just dont get a pwm fan and you should be good.
