I can't really comment on that. No idea how accurate the sensors are. Some of the sensors (eg the CPU sensor if measured through PECI) are extremely inaccurate at low temperatures. > - hysteresis values, i.e. pwm3_auto_point1_temp_hyst, behave strange.

The hysteresis should show a constant difference to the matching temperature, and is displayed as absolute temperature. For example, assume pwm3_auto_point1_temp_hyst is set to 20000 and pwm3_auto_point1_temp is set to 60000. If you change pwm3_auto_point1_temp to 30000, pwm3_auto_point1_temp_hyst should change to -10000.

It is only used if pwmX_stop_output_enable is set, otherwise the output drops to 0. Can you try this ?
