    The output is bogus, the fans are not turning. On #47 there above, I
    think the temperatures might be inaccurate, too. Since they'll go up
    and down as much as 8 degrees in a few seconds.

    I can set the fan speed manually. e.g.:

    echo 3500 > /sys/class/hwmon/hwmon0/device/fan1_output

    That helps some.
