Mine has a 3 pin header near C22, but the fan only takes two of the three pins. It has a 1998 date on the bottom.
Maybe you could get out the multimeter and see if one of those pinless vias labeled "R5" goes to +5 and the other to ground?
Ok, so got a better measurement of continuity:
Left pad of R5: Pin 3 of VR1, be 5 volts
Right Pad of R5 : A23 or A24
Upper Solder Pad: Pin 1 of VR1, Ground of VR1 used for adjusting Voltage
Lower Solder Pad: Ground
So it'd have to be a pigtail I solder in. Not sure if I really want to do that TBH, I'll have to mull over it.
