When VT1 temperature exceeds this boundary, FAN1 segment 2 speed
count register (index A5h x 16 or index A6h depending on the
FAN1_MODE[2] register) will be loaded into FAN1 expected count registers
(index 74h,75h).
When VT1 temperature is below this boundary - hysteresis, FAN1 segment
3 speed count registers (index A6h x16 or index A7h depending on the
FAN1_MODE[2] register) will be loaded into FAN1 expected count
registers(index 74h,75h).
Return 0 when read.
