Hello,
Today i got my EVGA 1080Ti SC2 Hybrid and i can't figure out how do i control the speed of a cooler on radiator...
I did instal latest drivers (tryed from Nvidia and from EVGA page, nothing changed. 
X1 Precision shows 0RPM and unable to control speed. Other software such as AIDA can't see speed either. 
Maybe i am missing something? Fan have 3pin connector as i see so it should be controlled and sent RPM info. 
Please help. I have bought this card to make my PC quieter and cooler, but looks like i am too cool now but load as hell....
Thanks in advance.
PC Specs Just in case.

    There is no fan control  for the radiator fan. It only has two wire control, +12v no PWM.  Like the rest of us with Pascal hybrids, if you're desiring rad fan control it's a bit complicated and requires using 3rd party programs to control a fan header on your motherboard based on the GPU temp. Or like me, you can replace your fan with say a couple of Scythe AP-13's in push/pull and run them at 90% and never hear a thing and have excellent temps and no need for fan control.

    Thanks for the reply.
    So am i understanding right? That there is VRM Fan that controls via PWM (it should be so) but the Fan on the rad is DC and have no control at all? That is really strange... 
    I found some info that there is another (empty PWM) on the board, so if ill buy PWM fan and redo the connector will i be able to control it?
    If so, that is really a strange way to save some money by EVGA.

    That is correct. You can control the speed of the PWM fan but you cannot control the speed of the fan on the radiator.  Honestly, why go to all that trouble? You can run push/pull fans in silence and get better cooling and save a few watts for the GPU to use. GPU Boost takes into account the power draw of the fans when calculating GPU load.
