Normally they turn off when idle but recently they won't turn on at all, even under load. Any ideas? I have set the fans speed to 100% in EVGA precision, as Gigabyte's own software is complete garbage, and the software allows me to do that but still says fan RPM is 0. What do?
If it is a new GPU, don't worry about fiddling with it. Send it back and get a warranty replacement/repair.
Trying to fiddle with anything will just void warranties. The seller is responsible if it is a new GPU and changing the fan curve directly does nothing.
