new YAML based configuration format. For this reason, several NixOS options

In addition, a new <xref linkend="opt-services.thinkfan.settings"/> option has

# ATTENTION: There is only very basic sanity checking on the configuration.
# That means you can set your temperature limits as insane as you like. You

# IBM/Lenovo Thinkpads (thinkpad_acpi, /proc/acpi/ibm)
# ====================================================
#
# IMPORTANT:
#
# To keep your HD from overheating, you have to specify a correction value for
# the sensor that has the HD's temperature. You need to do this because
# thinkfan uses only the highest temperature it can find in the system, and
# that'll most likely never be your HD, as most HDs are already out of spec
# when they reach 55 °C.
# Correction values are applied from left to right in the same order as the
# temperatures are read from the file.
#
# For example:
# tp_thermal /proc/acpi/ibm/thermal (0, 0, 10)
# will add a fixed value of 10 °C the 3rd value read from that file. Check out
# http://www.thinkwiki.org/wiki/Thermal_Sensors to find out how much you may
# want to add to certain temperatures.
