Seems like new Nvidia driver problem, they've probably changed something. I also tested my mod with 1070, but with some older driver like 441.xx and it for sure shows temperature, fan speed and power draw. I'm not updating driver because 1070 is quite old. Nvidia won't improve their drivers for mining, all they do is add support for new games and break something along the way  So there is no point in using new drivers with older GPUs for mining.

You can try to download older driver from here: https://www.geforce.com/drivers/beta-legacy

Later I will fix the issue with newer drivers.
