MacPro Fan PinOut

1 post in this topic

Recommended Posts

Hello, I'm doing a MacPro case mod project.  And I want to connect MacPro fans to motherboard or power supply, but I'm having problem connecting it. I can't find which pin goes where. Maybe someone knows how to connect it right ?


If I try connect first pin(GND) to ground and second pin (VCC) to +12V nothing happens.


If I try connect first pin(GND) to ground and second pin (VCC) to +12V  nothing happens and fourth pin (VM) to +5V 
My guess is:
GND = Ground
VCC  = +12 (but I'm not 100% sure)
O / P = Sense /Tacho (but I'm not 100% sure)
VM = PWM (but I'm not 100% sure)
I take some pics and mane diagram for more understanding if i helps.
Maybe someone know how make this thing work ?
