Does it have to run while listening/watching, or can it be turned on and then back off, or during some other times?
Noise then wouldn't be as integral an issue.
Insulating the housing the fan would reside in would attenuate the sound... like a whisper box for a projector or what ever they call that added box surrounding the PJ.
Speaking of which, with the lamp turned up to full brightness I can hear the PJ runing... until I turn up the sound of the whatever... Flick, CD, etc. Then of course, the noise is not a consideration.
Adding to the insulation of the fan housing, or even setting it into a duct work which turns by 90 degrees should also diminish the noted or audible sound of the motor itself. Further lengthening the ducting, and thereby removing the fan still farther away will surely decrease the noise it makes.
Go with a large register as you can too. that will help.
Good luck.
