[SOLVED] Fan not running (Acer Aspire One 722)

Hi all,

I have #! Waldorf installed on my Acer Aspire One 722 netbook. I've upgraded the RAM to 4 GB and put in a 128 GB SSD, and it runs nice and speedy. Trouble is it gets very hot, and I never hear the fan run, so I'm guessing something is messed up with the fan controls.
I'm pretty clueless as to where to start with this, and would appreciate some pointers. Thanks!

Re: [SOLVED] Fan not running (Acer Aspire One 722)

I'd install lm-sensors, then run sensors and see if the fan is actually on. If it isn't, or if you want more control over the fan anyway, I'd then install thinkfan and set up thinkfan.conf. The default safe thinkfan.conf settings are fine in my experience. You'll have to change acpi settings to experimental/user/acpi controlled or whatnot in /etc/modprobe.d/thinkfan.conf

Thanks a lot dura! I'll try those packages and see what it does.

How do I set up thinkfan.conf and change the acpi settings?

What happens if you run sudo thinkpad ? I think thinkfan might make a thinkfan.conf for you, and you might not need to alter acpi settings as you're not using thinkpad_acpi. Some Google foo will help you. Maybe hwmon will be needed.....not sure......

Thanks; I googled around, but the couple tutorials I found are written specifically for thinkpads (and using thinkpad_acpi, which my netbook obviously doesn't have). There doesn't seem to be a whole lot of documentation for the package.
Thankfully however I just ran "thinkfan", and so far I believe it has made a difference- temps are hovering a good 5-10 degrees C lower than before and the fans are definitely kicking in, so I believe this issue may be solved.
Thanks for your help and patience.

Re: [SOLVED] Fan not running (Acer Aspire One 722)

The fglrx driver that has been linked to might the root cause of your problems. Not sure. You might want to have a look into it though as it may be graphics which are making your temperatures rise.

And by the way, I think you can make thinkfan start at boot by putting it in rc.local before 'exit 0'.

Well, I'm not using fglrx- I had to with Statler to get full resolution but with Waldorf radeon works fine (better than fglrx, in fact).

Re: [SOLVED] Fan not running (Acer Aspire One 722)

I think that might be the point; switching to fglrx might reduce heat, but I wouldn't know...

Re: [SOLVED] Fan not running (Acer Aspire One 722)

Hm. I'm willing to risk a little heat in order to not use fglrx- I had extremely poor performance, plus it's nonfree. I'll see.
