# fan control-script<br />
#<br />
# based upon ibm-acpi 0.11 (experimental=1 !)<br />
#<br />
# eliminates anoying "fan always on" in battery mode<br />
# works with hysteresis (DELTA) so that always-turn-on/turn-off is avoided<br />
# fan acivates at MAXTEMP and cools down CPU, GPU etc. to MAXTEMP-DELTA than the fan is turned off<br />
# furthermore detects if AC is on and gives back fan control to default behaviour than<br />
#<br />
# one can change MAXTEMP and DELTA to individual values<br />
# but take care of your THINKPAD don`t melt it!<br />
#<br />
# have fun!<br />
