Need IBM server fan 7pin pinout

[USRoyce]

I purchased 4 IBM 80mm server fans (IBM Eseries Server Fan 80mm 06P6250 01R0587) and need to know what pins to connect to 12v power supply, there are 7 pins. I am not using in PC, I am using to cool powerful Peltiers and need the airflow these fans offer. Each fan has 2 counter rotating fans inside.
Any help would be great. I have searched the internet for hours and cannot find.

Find out what model server these fit in, then you may be able to find something on IBM's support site for that server model. There should be a maintenance manual somewhere.

Typically its the black and Yellow wire.
Black is the -, while yellow is the 12V.

The blue is the PWM sense... and the Orange is a 5V.

If its a counter rotating fan.. i would need to see a better picture as those require 2 fan header ports if i recall correctly.
