Stellen Sie die Korrelation zwischen Lüfterdrehzahl und Temperatur nach Ihren Wünschen ein.
/opt/fan-curve-control/config
# min_t is the temperature at which every temperature below it will cause
# the fan speed to be set to 0%, and everything above will be whatever the
# first speed in fcurve is (default of 25%)
# min_t2 is only used with the second fan speed and temperature arrays, so
# there is no need to change it unless you're using the second curve
min_t="25"
min_t2="25"
# How many seconds the script should wait until checking for a change in temps
sleep_time="7"
# By default it's set up so that when the temp is less than or equal to 35
# degrees, the fan speed will be set to 25%. Next, if the temp is between 36
# and 45, the fan speed should be set to 40%, etc.
# The last temperature value will be the maximum temperature before 100% fan
# speed will be set
# You can make the array as big or as small as you require, as long as they
# both end up being the same size
fcurve="25 40 55 70 85" # fan speeds
tcurve="35 45 55 65 75" # temperatures
# This value is used to determine the temperature difference needed to get
# the script to check for a new speed to apply. The default of this value
# is zero, which means the script will automatically calculate a value
# based on the temperature curves supplied below
force_check="0"
# These two arrays are for GPU's that have a secondary fan that you may wish
# to control seperately, especially if it is water-cooled.
fcurve2="15 30 45 60 75"
tcurve2="35 45 55 65 75"
# First number in array is fan 0, second number is fan 1, etc. If the number
# is 1, that indicates that the script should use the first curve for that
# fan. The same goes for the number 2.
which_curve="1 2 1 2"
# Only used for single-fan operation. If you have more than one gpu/fan but
# only want to control one of them, select which one here. Otherwise there
# is no need to change this setting.
default_fan="0"
# Similar to which_curve, but instead lets the script know which of the GPU's
# has which fan. i.e. element 0 in the array being set to 0 means that fan 0
# is assigned to GPU 0, element 1 is 0 too, meaning fan 1 is on GPU 0 as well

Ich habe drei Wege erlebt.
Da "Crontab" eine Gewohnheit hat, denke ich, dass es notwendig ist, den "Mechanismus des Stiefels" etwas genauer zu untersuchen.
Ich dachte, ich müsste rc.local berühren, ohne das Funktionsprinzip von systemd zu verstehen.
Der Autostart, den ich in diesem Artikel durchgeführt habe, scheint in der Endphase (99%) des Bootens und des vollständigen Systemstarts ausgeführt zu werden, sodass Sie sich keine Gedanken über Dienstabhängigkeiten machen müssen. Daher denke ich, dass es besser ist, "Autostart" für Anfänger zu verwenden, die versuchen, automatisch zu starten.
