In my honest opinion, if your intention is to flash your VBIOS so that you can enable your GPU to hit 0% fan speed, you need to be informed on a few things. First of all, this is super easy to do, although if you're somehow clumsy enough, you can end up bricking your card, so make sure you're not retarded before attempting this. Second of all, if you flash your VBIOS with any other GTX 1070 open-air cards VBIOS (The only ones that hit 0%), then you'll have another issue. Your 100% fan speed will no longer be 4000+ RPM, most open air cards run at ~2000 RPM max, so be sure about this. Third of all, if you're doing this for any overclocking reason, its not worth it. I too own a Founder's Edition GTX 1070, and I got really really lucky with it, I can do +150 on the core and +800 on the memory, stably, all day everyday and its been running like this since I bought it last September. It's good enough to achieve its maximum potential (-ish, on air anyway) without being damaged, although it may require that 100% (4000 RPM) fan speed to keep you under 65c, so do be wary that you won't be able to do any crazy overclocks afterwards (You'll climb over 80 degrees).
