FAN1_MODE[2] register) will be loaded into FAN2 expected count registers
(index 84h,85h).
When VT2 temperature is below this boundary - hysteresis, FAN2 segment
3 speed count registers (index A6h x16 or index A7h depending on the
FAN2_MODE[2] register) will be loaded into FAN2 expected count
registers(index 84h,85h).
