Zero Fan Mode is still available, but now only up to 55°C. Any higher and the fans start to spin with ~300rpm, then 600rpm @ 60°C and ~1000rpm @ 64°C. No problem for me, looks like a good solution (combined with the thermal pads).
Seeing the same here on my 1070 FTW. Running Heaven as "realistic" stress test, setting in the mid-60s with a fan speed of ~1100rpm (~35%). Surprised how conservative the fan speed is, means noise is actually fairly acceptable (that's the one thing I was afraid of with the new BIOS).
In general, this actually seems to be a healthier fan curve for the GPU as well compared to the previous one where it kind of settled in the mid 70s for me at marginally less noise. Once the thermal pads arrive, I think the whole thing will actually be okay (barring any surprises with the VRAM thermal pad contact upon opening the card). Not ideal and the ACX 3.0 really needs a revision in the future but as for what can be done right now? This might actually be okay.
I'd still like to see an "official" fan curve, though, just as reference for custom curves.
