Russ..it's a 3 pin connector to the MB. 3 holes in the connector go onto 3 pins on the MB. I can send you an actual picture from a website of my fans..

I can at least tell you if the plug is generic or not. MCMelectronics.com, jameco.com, jdrmicrodevices.com and many others sell retail and have individual parts like fans, in many sizes - shapes, etc. You mainly need to be concerned that it's 12vdc and the more cfm it's rated for the more air it pulls. The higher db it has the noiser it will be to you.
