So I went ahead and bought this fan and finally got it mounted in my helmet. Its pretty neat and quiet and light weight too. I dont feel any added weight in my helmet or feel the fan and battery pack against my head since the padding is slightly thicker than those parts. I might get somemore tubing to tie across the top vens of my goggles and poke holes along it so I can get even air in both eyes. What I like about this version of their fan system is that the fan itself is a cyclone styled fan, so I am able to mount the intake against one of the vent holes in my PT-alpha helmet to draw in cooler air from outside of my helmet. Just hope a bug or dirt gets into it and blown into my eyes, lol.
If anybody is interested, you can find the NVG mount both old fan system and new cyclone fan system at http://tabcbelts.homestead.com/Actio...NEMICHAEL.html
