- !/bin/sh
- fan control-script
- based upon ibm-acpi 0.11 (experimental=1 !)
- eliminates anoying "fan always on" in battery mode
- works with hysteresis (DELTA) so that always-turn-on/turn-off is avoided
- fan acivates at MAXTEMP and cools down CPU, GPU etc. to MAXTEMP-DELTA than the fan is turned off
- furthermore detects if AC is on and gives back fan control to default behaviour than
- one can change MAXTEMP and DELTA to individual values
- but take care of your THINKPAD don`t melt it!
- have fun!
- mk 05.05.05
MAXTEMP=51 DELTA=4
SWITCHTEMP=$MAXTEMP
- make sure the script doesn't leave the fan off on error
trap "echo enable > /proc/acpi/ibm/fan" EXIT
