FSTLMD (FAN_STALL Mode). Selects the fan conditions causing the detection of a fan failure, which sets both
the FANn_STALL status bit in the Status Register 2 (see Section 8.5.24 on page 165), and the FANn_STS bit
in the HM Sensor Status Register 2 (see Section 8.4.9 on page 148) to 1.
0: Either a fan stalled condition or a low speed condition, whichever occurs first (default)
1: A fan stalled condition only
