HP proliant ml330 cpu fan

I have a second cpu and fan for this server, but the fan I have has a different pinout than the board. My fan (not HP)only has 3 pins on the connector and the server mainboard has 4 pins for the fan connector. The original HP cpu fan has 4 pins, but only 3 wires going to the fan motor. Two of the wires connect together and form 1 before connecting to the fan motor.
Does anyone know the pinout of the board?
With this info I could change the fan pinout so it matches the board.

Re: HP proliant ml330 cpu fan


I've hunted but IO canna find the pinouts...

You might want to try running the fan, with an adapter like....

Akasa 3-pin to 4-pin Adapter Cable (I guess they sell these in the USofA)

From a spare PSU 4 pin end..
