Radiator fan is not XOC controlled. It is based on GPU temp but you cannot customize it, in fact you can't even see fan rpm.
If you check connector it has only 2 pins, ground and voltage, no pwm, no tachometer pin.
GPU just feeds higher voltage when temp raises.
yea, i just saw it now. It's finally spinning after reaching 50C+ temp. It does'nt make sense that evga added fan control on xoc but you can't even control it. They should have make it a 4 pin fan out of the box. 
i'l probably connect it back to commander pro so i can control the fan and i will also make it push and pull configuration
I have tried to control from Asus Fan Suite, BIOS or SpeedFan.
SpeedFan is probably the best as it's the only one that can read GPU temp, IF you can make it work, I couldn't, some of my MB fans just didn't show up.
Out of the rest, native control by GPU seems to be the best, no reason to reinvent the wheel, at least for me.
