Had the wife e-mail a picture and it doesn't really show what I wanted. This is 4, 40mm (I think), 3000RPM DC
computer fans. Still not sure how they will last but Nanotuners sell the exact one for their upgrade kits and they've done great so far. I know the cords look bad but I'm not running it under the hood until I decide how many fans I need (certainly not 4....LOL). Like I said, I have (2) 100w heaters set to 78.5-79 and these buggers still drop me to around 77 even when room temp is above 78.
You can't see the fans unless you open the feeding hatch (which I leave open). And the fans take up way less room than the camera angle depicts. I still feed, net, and even re-arrange with the monster tweezers with the fans in-place. The fans are zip-tied to a plastic bracket that is then velcroed to the hood so I can remove easily (although I used industrial velcro and about need a screwdriver to pru it apart)
