      which file must i edit to set the realm and hysteresis temperature
      values for the fans?

      ... Hi Erny, According to the man page (man i8kmon), it appears you want to create a file /etc/i8kmon or ~/.i8kmon and put the configuration lines in that. If

        Hi Erny,

        According to the man page (man i8kmon), it appears you want to create
        a file /etc/i8kmon or ~/.i8kmon and put the configuration lines in
        that. If your cpu temperature reads 85C (cat /proc/i8k), then your
        problem is not with the temperature ranges of i8kmon, though.

        Cheers,

        Kevin

        ----------

        CONFIGURATION
        The program has builtin defaults and temperature thresholds but
        users can specify their own settings in configuration files
        /etc/i8kmon and ~/.i8kmon. The daemon defines 4 states with different
        fan speeds ({0 0}, {1 0}, {1 1}, {2 2}) and for each state are
        defined the temperature thresholds which cause the switching to a
        higher or lower state. Furthermore each state can have different
        thresholds for operation on ac power or battery. For example the
        following configuration:


        set config(0) {{0 0} -1 60 -1 65}
        set config(1) {{1 0} 50 70 55 75}
        set config(2) {{1 1} 60 80 65 85}
        set config(3) {{2 2} 70 128 75 128}


        defines state 0 with both fans off, high threshold of 60 degrees (65
        on battery) and low threshold -1, which is actually never reached
        since 0 is the lowest state. When the high threshold is reached the
        program switches to state 1 (left low, right off) which has a high
        threshold of 70 degrees and a low threshold of 48 degrees. If the
        temperature drops below 48 the program will switch back to state 0,
        if it rises above 70 it will enter state 2, and so on. For better
        operation the temperature ranges should be overlapping with an
        hysteresis of at least 10 degree, i.e. 1={50 70},2={60 80} is better
        than 1={50 70},2={70 80}. It must be rembered that the low
        threshold of state 0 must be -1 and the high threshold of state 3
        must be 128.


        If your laptop has only one fan you should specify a'-' instead of
        the fan speed of the missing fan, for example:


        set config(2) {{1 -} 60 80 65 85}
