NCT6775F, fan readings can be divided by a programmable divider (1, 2, 4, 8,

16, 32, 64 or 128) to give the readings more range or accuracy; the other chips

do not have a fan speed divider. The driver sets the most suitable fan divisor

Voltage sensors (also known as IN sensors) report their values in millivolts.
