I’m glad you found my script useful. I have two comments. First, I’d say 63C is a bit hot for an idle eeePC. Maybe your fans were almost never spinning? 60C and below is more reasonable. Second, recal that you are calling your script from cron every hour! Maybe your intention was to call it every minute, and hence the “one” in the first column… But right now you the line is executed at every hour o’clock, plus one minute (00:01, 01:01, 02:01…). If that was actually your intention, then I’d say that controlling the fan speed every hour is a bit too sparse. You could call the script every 5 minutes like so:

0,5,10,15,25,30,35,40,45,50,55 * * * * /home/sindhu/myfan.sh

(If the script has no output, you don’t need to redirect anything to /dev/null).

sindhu@sindhu-eee:~$ crontab -l
# m h dom mon dow command
1 * * * * /home/sindhu/myfan.sh >/dev/null 2>&1

now the temp is around 60, i modded the script a bit (the temps part), maybe i should tweak it some more.
