Sorry for the late reply...I just noticed this.
The sound difference was noticeable, but not huge, although I had just bench tested it. I'd say maybe 20% louder right up against the plastic.
There was also another big reason I wanted to raise the fans...in the orientation I wanted, sucking heat up and out of the mask, there's no "guard" on the underside and having the spinning hub of the fan close to the plastic might cause it to jam.
