   # divider with both resistors equal to 34K, yielding a voltage one half of the power supply.

Thanks for sharing this! I created my own config with the help of this and A-Tuning.

@petersulyok That's awesome! Each config is a little different, but I can say it's sure nice to have enough functional sensors to know what's going on.

Thank you for the configuration file, my motherboard is ASrock H310CM ATX/AC, can you help me create the configuration file?
