71 These chips also have fan controlling features, using either DC or PWM, in
88 Both PWM (pulse-width modulation) and DC fan speed control methods are
99 There are 2 modes to specify the speed of the fan, PWM duty cycle (or DC
101 mode where the actual RPM of the fan (as measured) is controlled and the speed
102 gets specified as 0-100% of the fan#_full_speed file.
105 whole lot of a difference when modifying fan control settings. The only
106 important difference is that in RPM mode the 0-100% controls the fan speed
107 between 0-100% of fan#_full_speed. It is assumed that if the BIOS programs
108 RPM mode, it will also set fan#_full_speed properly, if it does not then
109 fan control will not work properly, unless you set a sane fan#_full_speed
116 Three different fan control modes are supported; the mode number is written
123 fan#_full_speed by writing to the pwm# file. This mode is only
124 available on the F71858FG / F8000 if the fan channel is in RPM mode.
127 You can define a number of temperature/fan speed trip points, which % the
128 fan should run at at this temp and which temp a fan should follow using the
134 The fan speed is regulated to keep the temp the fan is mapped to between
