So that's what one looks like without roof glop from edge to rim!
The road noise is significant on mine, however a cover eliminates the majority of it, and the actual noise level isn't so much a problem as the proximity to the driver. I would think in the rear it wouldn't be noticeable at all.
Camping World sells a foam plug for the fan opening. It is mostly for cold weather insulation, but it should also reduce the noise.

I tried the foam pillows but they didn't fit the Fantastic Fan for beans. I haven't found it necessary to put a shade on it even when I'm on night shift and sleeping during the day. I also crack the vent just to keep moisture levels down and air coming in "just in case".
saabman---I haven't noticed any increased noise level while driving on the interstate, most likely because it is located in the rear.
