does anyone have experience with pinout on server fans ? I have 2 different ones, but same brand name. I'd like to be able to power them up.
do they need a drive circuit or can they be powered up as is ?
i tried to search for a diagram, but haven't had much luck. I'm probably not using the right search terms.
but these are the 2 fans i have made by SUNON, PMD1204PPBX-A and PMD1204PJB1-A

The labels on the fans say what is needed. 12V DC for both, 1A or 1.23A max draw. For slower speed use a lower voltage, or a series resistor, or (for better efficiency) 12V PWM. For reversible variable speed, apply PWM through an "H" bridge.

Dyarker>>I know what voltages it needs, but I need a pin out.. There's several wires on these fans..

Re: server fan diagram
I finally figured it out, thru trial and lucky no error.
The PPBX-A uses Red and Brown for positive.
And Black and Grey for negative
.
The PJB1-A used only the Black for Negative and the Yellow for positive
.
I'm really amazed at how much air these things move, almost like mini leaf blowers
