If for some reason Afterburner doesn't let you control the fan speed, you could try Speedfan.http://www.almico.com/speedfan.php
I downloaded this but it asked for the vendor for the cand in a drop down menue, and Nvidia isn't listed. so it wouldn't let me do it. all the other EOMs were there, gigabite, MSI, ASUS, etc...But no NVidia
Hi Vinkman,All those EOM's make Nvidia GTX 1080Ti's so I would think that MSI's Afterburner software would work w\ your 1080Ti as well.Did you order your 1080Ti direct from Nvidia?This is a new feature that MSI has coded into their Afterburner software recently.....as of Afterburner 4.3.0 I haven't seen the software ask in a dropdown menu the specific vid card vendor of a specific vid card model........assuming that this would be the same for AMD cards as well........I'm actually using MSI Afterburner software w\ my Sapphire AMD Radeon R9 Fury X vid card as MSI also makes AMD Radeon vid cards so their software is both Nvidia & AMD compatible.........Hope you get it sorted out.........
