This register controls the FAN2 duty movement when temperature
under (highest boundary – hysteresis).
0: The FAN2 duty will decreases with the slope selected by
FAN2_RATE_SEL register.

1: The FAN2 duty will directly jumps to the value of SEC2SPEED2
register.
This bit only activates in duty mode.
This registers companying with FAN2_TEMP_SEL_DIG select the
temperature source for controlling FAN2. The following value is
comprised by {FAN2_TEMP_SEL_DIG, FAN2_TEMP_SEL}
000: fan2 follows PECI temperature (CR7Eh)
001: fan2 follows temperature 1 (CR72h).
010: fan2 follows temperature 2 (CR74h).

10
011: fan2 follows temperature 3 (CR76h).
100: fan2 follows IBEX/TSI CPU temperature (CR7Ah)
101: fan2 follows IBEX PCH temperature (CR7Bh).
110: fan2 follows IBEX MCH temperature (CR7Ch).
111: fan2 follows IBEX maximum temperature (CR7Dh).
Otherwise: reserved.

Address Attribute Default Value
Description
FAN3 count reading (MSB). At the moment of reading this register,
the LSB will be latched. This will prevent from data updating when
reading. To read the fan count correctly, read MSB first and followed
read the LSB.
