If you know the address of the chip, use a 'force' +parameter; this will put it into a more well-behaved state first. + +The driver implements three temperature sensors, seven fan rotation speed +sensors, nine voltage sensors, and two automatic fan regulation +strategies called: Smart Fan I (Thermal Cruise mode) and Smart Fan II. +Automatic fan control mode is possible only for fan1-fan3. Fan4-fan7 can run +synchronized with selected fan (fan1-fan3). This functionality and manual PWM +control for fan4-fan7 is not yet implemented. + +Temperatures are measured in degrees Celsius and measurement resolution is 1 +degC for temp1 and 0.5 degC for temp2 and temp3. An alarm is triggered when +the temperature gets higher than the Overtemperature Shutdown value; it stays +on until the temperature falls below the Hysteresis value. + +Fan rotation speeds are reported in RPM (rotations per minute). An alarm is +triggered if the rotation speed has dropped below a programmable limit. Fan +readings can be divided by a programmable divider (1, 2, 4, 8, 16, 32, 64 or +128) to give the readings more range or accuracy. + +Voltage sensors (also known as IN sensors) report their values in millivolts. +An alarm is triggered if the voltage has crossed a programmable minimum +or maximum limit. + +Alarms are provided as output from "realtime status register".

At first a wanted temperature and interval must be set. This is done +via thermal_cruise# file. The tolerance# file serves to create T +- tolerance +interval. The fan speed will be lowered as long as the current temperature +remains below the thermal_cruise# +- tolerance# value. Once the temperature +exceeds the high limit (T+tolerance), the fan will be turned on with a +specific speed set by pwm# and automatically controlled its PWM duty cycle +with the temperature varying. Three conditions may occur: + +(1) If the temperature still exceeds the high limit, PWM duty +cycle will increase slowly. + +(2) If the temperature goes below the high limit, but still above the low +limit (T-tolerance), the fan speed will be fixed at the current speed because +the temperature is in the target range. + +(3) If the temperature goes below the low limit, PWM duty cycle will decrease +slowly to 0 or a preset stop value until the temperature exceeds the low +limit.
