Being designed to cool a graphics card it's actually a very quiet and powerful fan.nice work, interesting fan.
I used this one: http://www.thingiverse.com/thing:128526
uses a standard 40mm x 10mm fan

I recently bought my first 3D printer via Craigslist--a Solidoodle 2 Pro. It's a cute little printer but the Devil is in the details and many stock features essentially need upgrading or workarounds. In this instance, my stock Solidoodle 2 X-axis motor was so hot to the touch that it startled me--it had neither a heat sink nor fan. The Y and Z axis motors wick away heat because they're bolted directly to enclosures metal frame.
My first fix was to super glue a box fan onto a generic part printed from Thingiverse. The fan was about twice the sizeof the motor. I wanted something smaller. I had an old ATI graphics card laying around with a 12V Sunon 125010VX-A ATI graphics card fan and having just completed the Instructables 3D printing course with Fusion 360 decided to apply my newly learned skills to designing a part around the fan and the motor.
Print this thing and screw in the fan with logo side facing out (see photos). Press fit onto NEMA 14 motor to provide constant cooling for the Solidoodle 2 Pro X-axis motor. I soldered headers onto my stock Sanguinololu board for 12V and GND. It might also be possible to splice into the extruder fan wire to provide power. The motor now is cool to the touch even during 10+ hour prints.
