Worked like a charm.

I added a header just in case the fan dies, i can replace it easily. I enabled RH & Slic3r for fan support, finally I created my own fan mount and bolted it to the side where the extra extruder fan mounted I used those pins to drive the E3D. I get terrific prints!

If everything looks good i'd say its a bad fan. Try and hook up an extra fan or use a multimeter on the connections to check for power. That is the easiest way to tell if its the fan or connections.

I picked up an innova and couldnt be happier. Works for simple things and home reapiars.
