The 2 slopes can be obtained by setting PWM1~PWM3 and Temperature1~Temperature3 through the
registers. When the temperature changes, FAN Output will calculate the DC/PWM output based on
the current slope. For example, in the following figure, T1~T3 are the temperature set and DC/PWM1
~ DC/PWM3 are the fan output set. Assume Tx and Ty are the current temperature and DC/PWMx
and DC/PWMy are the fan outputs, then
The slope:

The temperature sensor is selected by Bank0 Index 75h, bits 3~1 & Bank1 Index 5Eh, bits
3~1.
The fan output (SYSFANOUT, CPUFANOUT0, AUXFANOUT & CPUFANOUT1) is selected
by Bank0 Index 75, bits 5~4 & Bank1 Index 5Eh, bit 5~4.
