I have a Gigabyte GTX 1070 G1, and if my case is vertical (fans parallel to the floor), I have the grinding noise when the fans start spinning. When I'm not gaming they "spike", starting and stopping every minute or so, it depends on the temperature, if I'm watching videos etc. Every single time they start, I hear that noise. I'm using the latest BIOS 86.04.50.00.7A.Some people told me, that if you turn the PC Case upside down, the grinding sound is disappears. Is it so?
However, if the case is horizontal (fans perpendicular to the floor), there is no noise. I want to have it vertical, so my "fix" is disabling 3d active fan. Sometimes the card seems to ignore this option and stops/starts the fan anyway, so I use manual settings instead. This way I can keep them spinning all the time. My PSU makes more noise, so I guess it's ok. It may be a problem if you have a fanless PSU and want total silence, not sure. The problem is every time I reboot, the fan curve is blank, the grinding comes back, and I have to deselect and select the option again. So I just suspend the computer, and that's how I get rid of the noise.
I watched a youtube video where a guy explained that same thing. I pushed the wires as much as I could, as the instructions say, but it didn't work. I don't think this is the problem my card has. I mean, they don't touch the fans, and if for some reason they do (because of vibrations when they start spinning or something), it's not a problem I have been able to fix. I just can't push them more, they are fine.Also, many people told me that the grinding sound appear when the fan touches the wire. This is true?
My card has an extremely loud coil whine when I'm gaming. I can't hear it with my headphones on, but it is unfortunate, because I really wanted a card without this problem. My previous gpu had it too, it's a common problem, I tried with 3 different PSUs and there was no improvement.
Also, every time I start gigabyte xtreme gaming tool, it executes nvflash.exe that complains about firmware image filename not having a valid extension. Not sure why that happens but I wish it didn't, it's only a console window flashing, but it beeps, it's annoying. I would like to know if I'm the only one with this problem.
The gpu has nice temperatures and performance, but these things are unfortunate and I wish I could return it and get another brand. I wish the reviews I read had warned me about them. The problem is other brands may have other problems, like fan noise that is permanent instead of only happening when starting, etc. Anyway, it's too late, and I've learned to ignore this things and enjoy the 90+ fps I usually get.
