I wrote a little script that runs as a daemon and controls the fan in the EeePC.

To run is all you need to do is add to /etc/rc.d/rc.local:

Lots of eee "fans" will be happy with this, thanks, Dougal. Smile

Thanks Dougal. It's important to mention that the "eee" kernel module must be installed and loaded. This module is provided by the eee-fan-CPU-0.2-k2.6.25.16.pet, available here -

I updated that post to link to this post.

Dougal · Do I need to install eee-fan-CPU-0.2-k2.6.25.16.pet as well?

[quote="Dougal"]
Hardinfo will not give you that info because the eee uses its own "uniq" interface for those things... hence the need for various specialized tools for everything.

@Dougal: Thanks for your work. using gtkdialog for configtool was a good idea. I adopted your package to run script as daemon on arch linux. Just had to add a line in eee-fan-ctrl.sh to trap SIGTERM when sending the kill command and to do an clean shutdown and set fan to autocontrol. I also wrote a script to start as daemon, placed in /etc/rc.d/ .
Maybe you're interrested in the changes I made, so I put the packagesource as attachment.

Yes, it's the line saying:

may be it's possible to share your experience on how one must use this eee-fan control

i do manually turn off the fan at start and wait untill the temp gets about 51-54 degrees and only then turn it on ( 20%)
the temperature stays at about 50-52 degrees.
also i use cpu scaling with cpufrequtils( took from slackware)

I've updated the dotpet with some minor changes (and the "clean" exit).

I've also added a "verbose logging" option, that makes it log the temperature every time it is checked, so you can plot the cooling rate for different fan speeds... it could help decide on the best settings.

I've also included in the config gui mention of something I keep forgetting: the daemon will not accept temperatures below 30 degrees or above 80 degrees from the configuration.
The reasoning behind this is:
- If you set the lower limit too low, the fan will probably never stop (since you just can't bring the temp that low...)
- If you set the high limit too high, you might damage the processor...
Note that I just made up those limits, so if someone wants to google and find the critical temperatures for the processors used in the eee I can adjust it appropriately...
(These limits are now set at the end of the config file, so you can change them manually.)

just to share my experience with a eeepc 901 unit:

Fan control works a treat - it is set to run at 40%. However, when my power plug is connected up to the laptop, temperature climbs up to 60degC +/- 3degC. The bottom gets much warmer then say the Ubuntu 8.04 install that i was running.
My fsb is set to a 'powersave' setting (i hope) at '75 50 0'.
regular cat /proc/eee/fsb does confirm that the setting is set at these values.

Anyway, will try a few things out to see if can sort out this problem -else, puppy 4.1.1 NOP with XFCE is proving to be snappy, faster bootup and generally just as fun as the heavier distros.

Many thanks to BK and team incl. Dougal for getting these netbooks to almost full functionality!
