142 Both PWM (pulse-width modulation) and DC fan speed control methods are
144 motherboard, so the driver assumes that the BIOS set the method
149 vica versa. So the temperature zone trip points 1-4 (or 1-2) go from high temp
154 voltage) mode, where 0-100% duty cycle (0-100% of 12V) is specified. And RPM
156 gets specified as 0-100% of the fan#_full_speed file.
158 Since both modes work in a 0-100% (mapped to 0-255) scale, there isn't a
160 important difference is that in RPM mode the 0-100% controls the fan speed
161 between 0-100% of fan#_full_speed. It is assumed that if the BIOS programs
162 RPM mode, it will also set fan#_full_speed properly, if it does not then
163 fan control will not work properly, unless you set a sane fan#_full_speed
166 Switching between these modes requires re-initializing a whole bunch of
167 registers, so the mode which the BIOS has set is kept. The mode is
