Fan running all the time at high speeds (high speed)

marote · 2011-08-16 21:16:13

Hello fellowones,
Im new on this of Arching and i just installed a fresh version of Arch in my laptop (from the Archboot version) and im having some problems with the fan of my notebook, increasing temperatures.

I think perhaps the problem resides in the open drivers of the ATI video card, because i had some temperature problem with them when i was tasting others distro (Ubuntu; xUbuntu), but the thing is i can not install the privative drivers from ATI. But then i saw the same problem (the fan running at hig speeds, but lower temperatures) when i boot the system withouth the open drivers with runlevel3.

So i think i could need some help with this problemita.

Thanks!

hi
laptop model?

Hi Marote,
first, welcome to the forums!

Considering your problem, similar topics were discussed quite often. Just search the forums for them and come back - or better yet, open a new thread - if there are any specific questions left.

anything else, at your services

bernarcher:
i already searched and tried the things posted there with outstanding failures, i am still trying and reading posts (and wiki) about installing privative ATI graphic drivers. But i thought that creating a post with my personal issues could be more adecuate than ask them in others posts.

Marote,

Opensource ati drivers include powersaving capabilities which can be controled by "echoing" different values into specific "sysfs" files. It's described in the Wiki at this location:
https://wiki.archlinux.org/index.php/Ati#Powersaving

Furthermore, if your laptop is new... they tend to have two graphic chipsets. If that's your case and both are ATI chipsets, you can manually turn one off, so that both are not active at the same time. Though not specific to your laptop, the steps detailed in this page are valid for you:
https://wiki.archlinux.org/index.php/Ac … e_Graphics

Anyway, if you use ATI Catalyst drivers, you can do all these tasks from it's GUI tool (indeed, opensource drivers way do NOT work when using Catalyst). The easiest way to use Catalyst is activating its repo. Take a look at this page:
https://wiki.archlinux.org/index.php/Un … positories

Hope it helps!

Thanks mikioma.
I will try all of them.
I also notice that without any graphic card driver (booting from runlevel3), the system behaves the same way, fan running all the time and high temperatures. Why could it be?

Thanks!

Marote,

That's a question I've asked myself saveral times I think the reason is that the graphic card boots up in a "default" state... and my guess is that such "default" state is something like "full performance, full fan, drain the battery as fast as you can", or something like that regardless the runlevel you're at and up until someone instructs the graphic driver to switch to another power state.

When using opensource driver, you can do this whether you're on X or not; it's just a matter of setting specific values into sys files that are available as long as sysfs is. I don't know about catalyst, though.

All in all... that's my guess...

Arch Linux
