Do you undervolt/overclock your Nano? I have Fury's and would like to drop my power draw. What's your settings?
nothing!
off the box on Windows 10 (Pro)
install 15.12 drivers
set power limit 50%
i don't play with volts or OC of the Nanos i get electricity pretty cheap like 0,05 per kW (normal consumer pay like 0,23 per kW)
