Got my EVGA GTX 1070 FTW today. Card runs great, but the fan motors seem to be defective. At idle, the fans try to engage. They do fully engage at the temp target, but sometimes only one fans spins up while the other lags behind. I contacted EVGA support, and it needs to be replaced.
Edit: I uploaded a video. If you have an EVGA card, I'd check to see if your fans are doing the same.
Edit2: EVGA support says this is normal, and a replacement would do the same thing. Anybody else with an EVGA card experiencing fan behavior like mine?
Same here that's normal. They don't spin until certain temp. They can be twitchy once they do would be fine. You could just create a custom fan curve to have them work all the time if you want.
