# 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
|
|
# can do anything stupid, e.g. turn off your fan when your CPU reaches 70°C.

|
|
# That's why this program is called THINKfan: You gotta think for yourself.

|
|
# ====================================================
|
|
#
|
|
# 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:
|
|
# sensor /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.
|
|
|
|
# Syntax:
|
|
# (LEVEL, LOW, HIGH)
|
|
# LEVEL is the fan level to use (0-7 with thinkpad_acpi)
|
|
# LOW is the temperature at which to step down to the previous level
|
|
# HIGH is the temperature at which to step up to the next level
|
|
# All numbers are integers.
