1) The last NVIDIA driver indeed made the situation better, now at idle fans doesn't spin max %. But after some time idk exactly why but fans issue is happening again. Over time it got worse and worse. First fans started spinning on the lowest "consumption" and then they run 1000+ RPM almost all the time.
2) Tweak or afterburner doesn't work correctly at all. I guess it's related to problems with BIOS. On the screenshot, for example, if I set middle fan to 30% it indeed does so - fan stops (Why tho? I think that's also incorrect especially if you consider next sentence but THAT is still better than what's happening to side fans). But below 30 for some reason it runs at 53%. And above 30% relevantly to the slider.
The most interesting part: side fans slider doesn't work. It completely ignores any % and works on its own. At idle GPU-Z shows that Fan 1 works at 53% 0 RPM and Fan 2 is 53% and 1000-1100 RPM. Fans registration smh only works correctly for middle fan. Tweaks gather wrong stats on left-right fans and cannot operate them.
I guess Asus fked up somewhere with the right/left fans indicators sampling.
I'd suggest don't use Tweak or Afterburner at all because if you do so fans will run full capacity all the time. Only Nvidia driver reinstallation can make it better.
ASUS NEED to address this issue asap. GPU is hardly usable when all I hear while doing NOTHING are Fans running full speed somewhere for no reason. And the last BIOS update was almost 2 months ago. Like wth?I also heard some people doesn't have noise issues from the start. Idk if that information is true. And I also don't know if the problem is lies only withing my GPU. I hope ASUS will make an answer if this a known bios issue or this exact GPU defect.
P.S. Text contains some mistakes and explanation problems, engrish is hard.
