I have an old HP proliant ml150 g6 that I am going to use for handbrake encoding. It was originally a single quad core cpu. I bought two second hand 5540 xeons, when I installed them the server now requires another system fan to be installed, I have plenty of pwm fans and would like to use one of these rather than buying a $30 fan.
However when I plugged the pwm fan into the fan header the fan does not work. I'm thinking that it is the wiring but I'm not familiar enough with wiring to figure it out and I don't want to burn anything out. Connector on the motherboard

Solution
They should be:

Black = ground
Orange = open-collector tachometer
Red = +12 VDC
Yellow = open-collector, low-pass/high-fail, trip-point (speed) and locked rotor alarm
Blue = ground
Green = pulse-width modulated speed control

Ah, thank you! Using what you said and a pwm wire diagram I was able to get them to work properly.

I´ve an fan from an HP Server with 6 Pin connection (Nidec Beta V Series TA600DC) .
Witch wired must be connected for simply works on an 12 V power supply ?
Black (-) and Red (+) connect with 12Volt DC but Fan not works.

Wow I had forgotten about this thread. I don't remember off the top of my head but I will look into it when I get home.
