should be adjusted to max speed when the CPU gets too hot.

For example, if the “lo-limit” was set at 35ºC, “PWM start” at 30%, “PWM gradient” at 1.56%, and “hi-limit”

at 65ºC, then the fan will initially be at 30% duty cycle. At each degree of temperature increase, the fan

will increase 1.56% duty cycle. Therefore at 36ºC, the fan will operate at 31.56%, at 37%, it will be at

33.12%, and so on. At 65ºC, the fan will jump to 100%, and decrease when the temperature lowers.
