ok, if you want to put in a cheap switch or cheaper jumper to tell it to read for ground that would be best.

for the intial testing I will just leave it sensor wired without the sensor so it stays on full time just to try and burn out the fan.

Once I verify the fan is good to go with your controller, I will test out the controler alone for drivablility.
If you mail a sensor with it, I will test out both logic circuits. with a ground and with a temp sensor.
