Hello! Is it possible to control the fan speed on my 8600m GS? In Rivatuner there isn't the tab for Low-Level Fan Control....Is there a PowerUser option to enable to have this control? Perhaps I have to use NVStrap driver and check "Unlock Porfessional capabilities"? Or it is impossible with 8600m GS? What is NVAPIFanCOntrol, and where is this key? Thanks
