You can find it here (nct6775.ko for unraid-5.0.5): http://lime-technology.com/forum/index.php?topic=32057.8
Thanks. Turns out to have been a dead end for me. Not sure what I need. sensors-detect gives me coretemp and then an unknown chip trying family VIA/Winbond/Nuvoton/Fintek. From some other searches I had seen about Nuvoton I thought this might help me but unfortunately not.
I know there are others using the ASUS H87-I motherboard here, so if anyone gets this working let me know.
Seems you need asus_atk0110.ko. Try to do modprobe asus_atk0110.ko and see if that helps.
