95 The chips support up to 25 temperature monitoring sources. Up to 6 of those are
96 direct temperature sensor inputs, the others are special sources such as PECI,
97 PCH, and SMBUS. Depending on the chip type, 2 to 6 of the temperature sources
104 The temperature sensor sources on all chips are configurable. The configured
105 source for each of the temperature sensors is provided in tempX_label.
108 either 1 degC or 0.5 degC, depending on the temperature source and
109 configuration. An alarm is triggered when the temperature gets higher than
110 the high limit; it stays on until the temperature falls below the hysteresis
128 In this mode, the chip attempts to keep the measured temperature in a
129 predefined temperature range. If the temperature goes out of range, fan
132 The mode works for fan1-fan5.

137 pwm[1-7]
138 - this file stores PWM duty cycle or DC value (fan speed) in range:
142 pwm[1-7]_enable
143 - this file controls mode of fan/temperature control:
146 * 1 Manual mode, write to pwm[0-5] any value 0-255
152 pwm[1-7]_mode
153 - controls if output is PWM or DC level
159 -----------------------------
161 pwm[1-7]_temp_sel
162 Temperature source. Value is temperature sensor index.
165 pwm[1-7]_weight_temp_sel
166 Secondary temperature source. Value is temperature
168 Set to 0 to disable secondary temperature control.
170 If secondary temperature functionality is enabled, it is controlled with the
173 pwm[1-7]_weight_duty_step

191 If the temperature is in the range defined by:
193 pwm[1-7]_target_temp
194 Target temperature, unit millidegree Celsius
195 (range 0 - 127000)
197 pwm[1-7]_temp_tolerance
198 Target temperature tolerance, unit millidegree Celsius
200 There are no changes to fan speed. Once the temperature leaves the interval, fan
201 speed increases (if temperature is higher that desired) or decreases (if
202 temperature is lower than desired), using the following limits and time
205 pwm[1-7]_start
206 fan pwm start value (range 1 - 255), to start fan
207 when the temperature is above defined range.
209 pwm[1-7]_floor
210 lowest fan pwm (range 0 - 255) if temperature is below
212 stop if the temperature is below the defined range.

248 critical temperature mode, in which the fans should run at full speed.
250 pwm[1-7]_auto_point[1-7]_pwm
251 pwm value to be set if temperature reaches matching
252 temperature range.
254 pwm[1-7]_auto_point[1-7]_temp

274 connected to anything and floats, or that it is connected to some non-standard
275 temperature measurement device. As a result, the temperature reported on CPUTIN
277 temperatures, and in some cases the reported temperature declines if the actual
278 temperature increases (similar to the raw PECI temperature value - see PECI
280 boards. The CPU temperature on ASUS boards is reported from PECI 0.
