----------------
-pwm[1-5] - this file stores PWM duty cycle or DC value (fan speed) in range:
+pwm[1-7] - this file stores PWM duty cycle or DC value (fan speed) in range:
0 (lowest speed) to 255 (full)
-pwm[1-5]_enable - this file controls mode of fan/temperature control:
+pwm[1-7]_enable - this file controls mode of fan/temperature control:
* 0 Fan control disabled (fans set to maximum speed)
* 1 Manual mode, write to pwm[0-5] any value 0-255
* 2 "Thermal Cruise" mode
* 4 "Smart Fan III" mode (NCT6775F only)
* 5 "Smart Fan IV" mode
-pwm[1-5]_mode - controls if output is PWM or DC level
+pwm[1-7]_mode - controls if output is PWM or DC level
* 0 DC output
* 1 PWM output
Common fan control attributes
-----------------------------
-pwm[1-5]_temp_sel Temperature source. Value is temperature sensor index.
+pwm[1-7]_temp_sel Temperature source. Value is temperature sensor index.
For example, select '1' for temp1_input.
-pwm[1-5]_weight_temp_sel
+pwm[1-7]_weight_temp_sel
Secondary temperature source. Value is temperature
sensor index. For example, select '1' for temp1_input.
Set to 0 to disable secondary temperature control.
If secondary temperature functionality is enabled, it is controlled with the
following attributes.
-pwm[1-5]_weight_duty_step
+pwm[1-7]_weight_duty_step
Duty step size.
-pwm[1-5]_weight_temp_step
+pwm[1-7]_weight_temp_step
Temperature step size. With each step over
temp_step_base, the value of weight_duty_step is added
to the current pwm value.
-pwm[1-5]_weight_temp_step_base
+pwm[1-7]_weight_temp_step_base
Temperature at which secondary temperature control kicks
in.
-pwm[1-5]_weight_temp_step_tol
+pwm[1-7]_weight_temp_step_tol
Temperature step tolerance.
Thermal Cruise mode (2)
If the temperature is in the range defined by:
-pwm[1-5]_target_temp Target temperature, unit millidegree Celsius
+pwm[1-7]_target_temp Target temperature, unit millidegree Celsius
(range 0 - 127000)
-pwm[1-5]_temp_tolerance
+pwm[1-7]_temp_tolerance
Target temperature tolerance, unit millidegree Celsius
there are no changes to fan speed. Once the temperature leaves the interval, fan
temperature is lower than desired), using the following limits and time
intervals.
-pwm[1-5]_start fan pwm start value (range 1 - 255), to start fan
+pwm[1-7]_start fan pwm start value (range 1 - 255), to start fan
when the temperature is above defined range.
-pwm[1-5]_floor lowest fan pwm (range 0 - 255) if temperature is below
+pwm[1-7]_floor lowest fan pwm (range 0 - 255) if temperature is below
the defined range. If set to 0, the fan is expected to
stop if the temperature is below the defined range.
-pwm[1-5]_step_up_time milliseconds before fan speed is increased
-pwm[1-5]_step_down_time milliseconds before fan speed is decreased
-pwm[1-5]_stop_time how many milliseconds must elapse to switch
+pwm[1-7]_step_up_time milliseconds before fan speed is increased
+pwm[1-7]_step_down_time milliseconds before fan speed is decreased
+pwm[1-7]_stop_time how many milliseconds must elapse to switch
corresponding fan off (when the temperature was below
defined range).
This modes tries to keep the fan speed constant.
-fan[1-5]_target Target fan speed
-fan[1-5]_tolerance
+fan[1-7]_target Target fan speed
+fan[1-7]_tolerance
Target speed tolerance
higher fan speeds with increasing temperature. The last data point reflects
critical temperature mode, in which the fans should run at full speed.
-pwm[1-5]_auto_point[1-7]_pwm
+pwm[1-7]_auto_point[1-7]_pwm
pwm value to be set if temperature reaches matching
temperature range.
-pwm[1-5]_auto_point[1-7]_temp
+pwm[1-7]_auto_point[1-7]_temp
Temperature over which the matching pwm is enabled.
-pwm[1-5]_temp_tolerance
+pwm[1-7]_temp_tolerance
Temperature tolerance, unit millidegree Celsius
-pwm[1-5]_crit_temp_tolerance
+pwm[1-7]_crit_temp_tolerance
Temperature tolerance for critical temperature,
unit millidegree Celsius
-pwm[1-5]_step_up_time milliseconds before fan speed is increased
-pwm[1-5]_step_down_time milliseconds before fan speed is decreased
+pwm[1-7]_step_up_time milliseconds before fan speed is increased
