OK I think this is more what you want.

Code:

#!/bin/bash

MAXSPD=80
MINSPD=20

if [ $# -lt 2 ];
then
echo "Usage: setfantemp.sh "
exit 1
fi

DEVICE=$1
SETTEMP=$2

export DISPLAY=:0.${DEVICE}

while true;
do
CURTEMP=`aticonfig --adapter=${DEVICE} --odgt | grep Temp | sed 's/.* \([0-9]*[0-9][0-9]\)\..*/\1/'`
CURSPD=`aticonfig --pplib-cmd "get fanspeed 0" | grep Result | sed 's/.* \([0-9]*[0-9][0-9]\)\%.*/\1/'`

echo -n "Set temp: ${SETTEMP}C Current temp: ${CURTEMP}C Current speed: ${CURSPD}% - "

if [ "${CURTEMP}" -ne "${SETTEMP}" ]; then
if [ "${CURTEMP}" -lt "${SETTEMP}" ]; then
NEWSPD=$((${CURSPD} - 1))
if [ "${NEWSPD}" -lt "${MINSPD}" ]; then
echo "MIN speed limit"
else
echo "Decreasing speed to ${NEWSPD}"
aticonfig --pplib-cmd "set fanspeed 0 ${NEWSPD}"
fi
else
NEWSPD=$((${CURSPD} + 1))
if [ "${NEWSPD}" -gt "${MAXSPD}" ]; then
echo "MAX speed limit"
else
echo "Increasing speed to ${NEWSPD}"
aticonfig --pplib-cmd "set fanspeed 0 ${NEWSPD}"
fi
fi
else
echo "Stable"
fi
sleep 10
done

Save to setfantemp.sh. To run:

Code:

# ./setfantemp.sh 0 55 &

That will set your target temperature for card 0 to 55C. The script will adjust the fan speed to hit that target.

Max fan speed and min fan speed are hard coded in the script to be 80% and 20% respectively. You can raise the max speed if your card isn't getting cooled to your target temp.

I didn't test yet, but seems good for my porpose... I will test later today, but I have one question.

this line is correct?

Code:

CURSPD=`aticonfig --pplib-cmd "get fanspeed 0" | grep Result | sed 's/.* \([0-9]*[0-9][0-9]\)\%.*/\1/'`

the get fanspeed 0 part... is 0 for device?
if yes, I will just change it to 1 over device 2, correct?
