And then set the pwm1 value to - control the fan. - - Each temperature channel can control all the 8 PWM outputs (by setting the - corresponding bit in tempX_fan_map), you can set the temperature channel - mode using temp[1-6]_pwm_enable, 2 is Thermal Cruise mode and 3 - is the SmartFanII mode. Temperature channels will try to speed up or - slow down all controlled fans, this means one fan can receive different - PWM value requests from different temperature channels, but the chip - will always pick the safest (max) PWM value for each fan. - - In Thermal Cruise mode, the chip attempts to keep the temperature at a - predefined value, within a tolerance margin.
