What I used was basically a 60x25mm dual ball bearing fan at 4500rpm. Branded
under the name "Cool-it Dude!" by computernerd.com (basically some fans that I
got a couple years ago with an over clocked Celeron)
I used a couple zip ties to suspend the fan just above the card and processor
in the Demarc aluminum enclosure. At 70' of POE, and an 18Vdc pwr supply, it
works just fine off J3.
