ATI Radeon VG card fan

[TOM REFF]

I am a physics teacher. I have a fan from an ATI RADEON VG card, P/N 7120035100G.
I can't find any specs for voltage, current, power, etc., for the fan.
My class has made a V vs. I graph of it to find R,
but I'd like to get the actual specs to see how close we got.
Thanks,
Tom Reff

Red wire (PC wiring convention)- should be 5v - that is nominal - actual may be 5.15v-5.2v as I recall.

ATX PSU is :
Yellow: +12V
Red: +5V
Orange: +3.3V
Black: Ground

Purple: 5V SB (standby voltage)
Green: /PS_ON (it can be shorted to ground to start PSU)
Grey: PWR_OK (status signal generated by PSU to indicate voltages are OK)
White: -5V (optional on newer ATX-2 PSUs)
Blue: -12V
