The IT8716F, IT8718F and later IT8712F revisions have support for

The IT8716F and IT8718F, and late IT8712F and IT8705F also have optional
16-bit tachometer counters for fans 1 to 3. This is better (no more fan
clock divider mess) but not compatible with the older chips and

+of the above chips is detected.
The IT8726F is just bit enhanced IT8716F with additional hardware
for AMD power sequencing. Therefore the chip will appear as IT8716F
The IT87xx only updates its values each 1.5 seconds; reading it more often
will do no harm, but will return 'old' values.
