Smart Fan
programmed by BIOS or application software. The programming method must be set fan configuration
at bank 0 index 04h,bit5-4,index 12h bit2~1 index 62h bit5~4.Before enabling Smart Fan
mode ,you have to set relative registers as table 7.4-2. In addition to the required registers, the device
has a the following registers that further configure and enable the fan speed control functionality .Then
Table 7.4-1 displayed current temperature and fan output value at Smart Fan
the table 7.4-2 used to setting at Smart Fan
