Start PWM Value
When CPU temperature arrives to the set value, the CPU fan will work
under Smart Fan Function mode. The range is from 0~127, with an
interval of 1.
Slope PWM
Choices: 1 PWM Value/℃ (def a ult ), 2 P W M Va l ue/℃ , 4 PWM Value/℃ , 8
PWM Value/℃ , 16 PWM Value/℃ , 32 PWM Value/℃ , 64PWM Value/℃ .
S1: CPU temperature is 60℃, and PWM v alue is 1 PWM/℃.
S2: CPU temperature is 60℃, and PWM v alue is 2 PWM/℃.
S3: CPU temperature is 60℃, and PWM v alue is 3 PWM/℃.
Increasing the v alue of slope PWM will raise the speed of CPU f an.
As in above diagram, when the CPU temperature reaches 60℃, the CPU
f an speed f or 3 PWM/℃ is higher than 1 PWM/℃ (S1<S2<S3).
