For automatic fan speed control (not limited to this chip), how much
can automatic control be configured?

Some configuration options I do think about:
- temperature thresholds
  (e.g. to choose balance between cool and silent)
- link between temperature input and controlled fan

Are such features provided by the chips (chips of direct interest to me
are IT8712F, nforce420, [W83697HG])

Depending on what chips are capable of, how much of it does lm_sensors
implement and how is it expected to be used?
