106 There are 4 to 5 fan rotation speed sensors, 8 to 15 analog voltage sensors,
111 source for each of the temperature sensors is provided in tempX_label.
129 Voltage sensors (also known as IN sensors) report their values in millivolts.
138 The mode works for fan1-fan5.

143 pwm[1-7]
144     - this file stores PWM duty cycle or DC value (fan speed) in range:
148 pwm[1-7]_enable
149     - this file controls mode of fan/temperature control:
152 	* 1 Manual mode, write to pwm[0-5] any value 0-255
155 	* 4 "Smart Fan III" mode (NCT6775F only)
156 	* 5 "Smart Fan IV" mode
158 pwm[1-7]_mode
159     - controls if output is PWM or DC level
