I remember replacing the HD on an imac before. It did the same thing fans will spin  at fast speed.

From what I remember the cable for the sensor plugged in from the logic board to the hard drive.

To remedy the issue, I shorted the two cables for the sensor (connect them together)

After that then it worked perfectly.
