What is the startup voltage on this fan? My PSU demands about 5v where it starts out slow then if it ever gets to 12v lookout.

Accepted Answer

The question isn't clear, as you asked it. A motherboard will alter a "run speed" signal to your fans to keep your PC cool with the least amount of noise (run speed signal is ideally not at 12V) but your PSU can give the same voltage to everyone if it has the Amps to do it. 
You should assume that all fans start at MAX speed/voltage at the moment of Boot Up & then vary as temperature allows.
