>Is there a way to quiet a ProFile, perhaps by replacing a fan?

The ProFile has no fan.

Usually the ProFile's "jet-engine" noise can be nearly eliminated by adjusting the static brush.

The static brush touches the bottom end of the spindle axle, and after some period of wear, can vibrate quite loudly.

If you (carefully) remove the hard disk assembly from the ProFile chassis, and remove the circuit board on the bottom, you will see the static brush. A small tweak sideways is usually all that is required to change the point of contact and stop the excessive noise.

Make sure that the brush is still making contact with the axle so that it can do its job, and do NOT "lubricate" the point of contact.

HTH, James
